Philips Streamium MCi500H/05 Dead / Faulty PSU

This Philips Straemium MCi500H was dead, no power.


NOTE !: as the messages have got quite long on this post, there is a 'Load more....' at the bottom that isnt very clear, if you cannot see your post / my reply make sure to hit this button !

Update: Repair service

Although I did not set up the blog post with a view to offering a repair service, there has been a lot of interest from people to get these repaired. I have successfully repaired many units, people seem to really like these and not want to throw them away.

So if you would like me to repair your Streamium MCi500H please feel free to get in touch.

Update: 2016

I have continued to have good success repairing these and from other models, I have done them for people all over Europe ! The same supply is used in the WAC7500 and I have repaired from the WACS7500 also. Had quite a few now with significant failures on the switching circuit, probably switching MOSFET failure which then takes out multiple components.

So please get in touch if you would like yours repaired.

I also have a listing on eBay as another way of getting in touch. Just search on 'streamium repair'



It was disassembled and the power supply fuse (PCB solder mount, 4A, circled in pcb pic) had blown.

The PSU was a kingwall ps131 300 e0, good old 12nc 3141 078 50341



Further fault finding showed the following components dead.

FET on heatsink
PWM IC
diode
high power resistor
bridge rectifier

All circled in this pic



no sign of any bad capacitors.

All the discretes were tested on diode check. The PWM IC was identified faulty by measuring across its rails, it was dead short.

Components changed and all running well again.



I couldnt find much on this PSU and no way to buy a repalcement, so was good to fix the original.

  1. Great work! Can you help me? I have the MCI300/12 with a Kingwall PS131-300-D0 power supply. It is the same like you have but without some power connectors.
    My problem is after a power failure the led of the power button only flash. After i have disassebled the radio i found out, that the problem is the 9V ECO voltage. When i playing a litte bit with a capacitor i get the radio to run. Can you help me where could be the problem?

    1. Hi Lowfinger,
      I have a similar problem with my MCi500H/12 and the Kingwall PS131-300-E0 power supply.
      Is it possible to repair the unit?
      How can I contact you? I didn't find the button. I'm not familiar to use blogs ;-) .
      Kindly regards

  2. Hey,

    It's the same power bloc for the MCI500/12, but the two primary electrochimic capacitor are 200 Volts and is it compatible with the french power (220v / 240 v 50hz) ?

    Thank's and regards

    2. Firstly, Thanks for your advices
      I've had very similar problem with my MCi500H.
      Initially, the screen blinked in black and white and when I turned off and turn on power, the LED of switching on power has started blinking.
      I've checked my components:
      FET on heatsink - fault, but not exactly the same - close a diode which you circled on pic)
      PWM IC - I don't how can I check is it OK, or not.
      diode - OK
      high power resistor - damage, but I can't read the resistatnce of resistror -
      bridge rectifier - OK

      However, before damage the resistor and FET i checked the voltage. I've got 5,2V, 12V, but 30V and 9V were not avaible on the output of supply module.

      Have you detail service manual of supply part. I've found Service Manual for MCI500H, but supply module is decribed quite generally.

      Regards

    3. Hi Lowfinger,

      Having similar issues as yours. Dead unit, dead power supply and as you can see http://s17.postimg.org/9wgo4v8y7/mci500h.jpg I have the IC right to yours that did explode.
      Could you please tell me what the ref is of this IC ? There isn't to much left to tell.

      Delete
    4. Hello, no problem, IC 101 is a TL384SP, it is the same as IC100 next to it. There is a very good chance that the FET it switches is short for it to end up looking like that.

      Hope that helps.

    5. Hi,
      Thanks for the tip. I'll order the components and hope I can fix it.

    6. Hi,
      Still strugling to make this power supply work.
      I suspect it is because of ZD004 which shows up as shorted. Do you know what it's zener voltage is ?

      Delete
    7. Hi, ZD004 is for the DC supply to the ICE3B0565. Data sheet shows supply range of 8.5v to 21v. Their dev board for this chip uses an 18v one so that would be a good choice or a close value if you don't have the exact one.

      If this diode is short the ICE3B0565 could also be dead, this chip generates the 9v eco rail.

      Hope that helps.

      Delete
    8. ... I just found some old notes from measuring on a working supply. The voltage is 17.7v.

      Delete
    9. Hi,
      Great update, I'll try a 18V zener see what I can get out of it.
      Thanks.

    10. Hi Lowfinger,

      Bad news, the new components didn't do the job, I guess some other parts are dead either.
      Thanks for your help anyway.

  3. Dear Lowfinger (or any other blogger), would you be willing to repair my Streamium 500H/12? I have exactly the some components burned as you. No technician in Paris is willing to repair it, and I dont have the expertise to repair it myself. It is just such a waste to throw the thing away.

    Kind regards and many thanks,

  4. How badly do you want this fixed ! ? If you are prepared to post the PSU to England (and pay for return post) (and risk it may still not work) I would have a look !

  5. Dear Lowfinger, I would be very grateful if you could have a look! Of course I would be willing to ship the PSU to England and pay for the return post. Would it be possible to send me your address? It is probably best if you send it to s a n d e r z b o r a y AT y a h o o . c o m.

  6. Hi

    I have a MCi500H/12 and the left speaker doesn't work. From googling, I suspect one of the capacitors has blown.

    Now, after a power cut, my power light flashes on/off but i cannot get it to boot up. From reading your blog, I suspect that more parts of the board may have blown.

    I note you are in England and I was wondering whether you would be happy to look at my Streamium and tell me if it can be repaired and if so to quote for such repairs. As you can guess, it's outside of warranty and I don't really want to pay Phillips' repair costs when there is no warranty to protect

  8. Hi there - my mci500h is also suffering from the flashing screen issue. The hard disk powers up but nothing is working. It happened after a mains power reduction. The streamium looked ok but I unplugged it to be on the safe side, or so I thought. The screen was flashing when I switched it back on. I notice mikecartwright.net sell a "repair kit" for the power supply which is all capacitors. Is the flashing screen problem capacitor-related? I would imagine it is as the from what I can remember capacitors smooth the output voltage, but I don't want to waste money if it's not. What do you think? Any help gratefully received! Cheers.

    ReplyDelete
  9. Hi, I have repaired four of these now (including Sanders and Schmunkee's above) with various power related faults. Non have been caused by failed capacitors but you can never rule it out. Your PCB fuse has not gone so the fault should not be too serious.

  16. Hi, I have the MCI500H/12. I plugged it to move it and when I plugged it back in the power button turns green and on the screen the Philips logo would come up but it would stay on that. Eventually the screen would flash black and the power button red and then again the power button turns green and the Philips logo comes up and it keeps doing this and over. When I called Philips suggested repair centre they said it's a power problem and wanted a lot of money to repair, more than half for what I paid for it.

    1. Hello, everyone (and Lowfinger)

      I have exactly the same problem as you, Nicolas. The component seems to be the famous ICE3B0565 Lowfinger is talking about on august the 30th (see above).

      Mine burnt and made the c008 capacitor explode too. Can someone tell me what is the value written on it, as I can't find it anywhere ?

      Thank you for you help, and best regards,

    After repair the PSU the MCi500 does not boot up.
    The Screen shows only philips.
    The Power Button is green. No Flashing!!
    The 3V,5V,12eco,12V and 30V lines are ok.
    Can it be a Fault on the Harddisk?On Linux i have only access to Partition 4-6.
    Has anyone a image from the first and second Partition of the HDD??

    1. If the problem is limited to the contents of your HDD, i.e. not in any flash memory of the main unit then restoring the HDD from a good drive may bring it back to life.

  32. Hi folks, when my MCi500h died I bought a S/H unit, without speakers, for spare parts, before attempting any repairs.
    My original unit started hissing from the RH speaker and I found it was pushing the speaker cone out about 5mm when switched on, although there was still some sound coming from the speaker presumably because the other half of one amp was still working but DC biased.
    I changed the amp IC which made no difference.
    I had two swelled capacitors, 1000uF and 470uF, in the part of the PSU that appears to power the amps directly with a ribbon cable which connects behind the amp heat sink. Replacing the caps hasn't cured the problem, but I haven't given up yet.
    Replacing the PSU has solved the problem, so now I want to repair the old PSU.
    If anyone knows what the PSU voltages and connector pin numbers to check are I'd be very grateful.

    In return I have a spare hard disk which has the correct structure and format from the spare unit I bought, so I could image the disk partitions and structure for anyone who needs to build a new hard disk, as I use Linux. If your MCi500h hangs at the boot screen it's possible that the HD or CD drive is faulty, as this is one of the things I noticed when I was building my working machine, if the HD or CD aren't powered or on the data bus the unit doesn't boot fully.

    Hope this might help someone, as I think that a working hard disk image would be very useful, and that someone can assist me to repair my old machine's PSU.

    Great blog Lowfinger, I might be asking you to repair my PSU if I can't fix it myself. ;) :D

    1. Hi Kim, good additional info there, I fixed one with a dead CD drive, as you say it just sits on the Philips screen, a donor drive and all was good.

      The excellent site Elektrotanya has the service manual for free download but annoyingly this does not include the actual PSU (subcontracted out) it will give you all the pin outs you need though, the amp has dual +30v supplies, maybe one of these is missing ?. If you ever wanted me to take a look at the PSU just drop me your email address.

    2. Hi Kim,
      I have an MCI500 with what appears to be a faulty hard drive, I removed it from my system when it looked like the psu was beyond repair and copied off the mp3s on a windows system with an EXTfs driver. Having, somewhat unexpectedly managed to get the psu working I have reinstalled the hard drive and cdrom, but the system now hangs on 'system starting, please wait'. Is there any chance of getting hold of the image data on your spare hard disk.
      I do have some expertise in fixing the psu on these units, so some form of trade might be feasible.
      Many thanks

    3. Hi Ralph, I'll have another look at the disc, it has a huge amount of heavy/death metal on it that came with my second hand machine, so I'll have to have a a look at it to see if there's anything worth saving, so that I can give you a clean image. I suspect that the best way is to do a factory reset before imaging. There are two partitions that even gparted doesn't recognise at the beginning of the disk, so I hope that these can be imaged or that the machine firmware initialises them. Whereabouts are you, maybe I could try to image a clean disk for you and send it by post if you're in the UK. Bear in mind Xmas is nearly here though ;) Missus will be keeping me busy :D
      If this works, maybe Lowfinger would like to keep a copy too, to pass on to others with a dead HDD?

      The MCi500h firmware can be downloaded from Philips site, I wonder whether the BIOS in the machine will boot it from a CD in the drive to create a new HDD image?

    Do you know the pin nos for the 30V supplies, I presume they come from the smaller header at the top of your photo that goes into the amp board adjacent to the amp ICs?

    It'd be good to have some dialogue about this machine :)

    I have Philips MCI300/12 Streamium Wireless Music Station (Mini Hi-Fi) that repeatedly loses sound on one of the speakers.

    2. Chris, I don't know how similar the 500 and 300 are, but the 500 has separate power supplies for right and left amps, so it's possible that one of them is dying, or a bad connection in the power supply plugs, or even a problem with the headphone socket or RH amp.
      The PSUs in these units are (IMHO) a horrible weakness, the electrolytic capacitors are very poor quality, pity Philips didn't specify them better from the supplier. :(

  35. Hi Lowfinger,
    Good news - my old PSU appears to be working, 30V at pins 1&5, looks nice and smooth on the scope.
    The unit boots up and runs, all the functions appear to be working (haven't checked the USB port, which wasn't working when I bought this unit) and I get sound from both channels, into a pair of old but matched car speakers.

    Works perfect into headphones too.

    Bad news - as before - on start up there's some crackling from the speakers, and a high pitched background (like switch mode noise) hiss from the RH channel (which was the one that had the problem before) so it looks like the Amp from my old unit was the problem all along (though I had some blown electrolytic caps which probably caused the fault in the first place, after I powered down to go on holiday)
    There's approx 0.3V DC bias on the RH channel output whenever the amps are powered, and HF superimposed on the audio which is reducing the volume from the RH channel about 30%

    The amp card from my newer unit works fine in the new unit with my old power supply.

    I'm looking at the amp card, but a combination of SMD and 60 year old eyes doesn't look good :(

    If I can't find it, do you fancy a go at repairing the card if I send the whole machine? ;)

  39. Hi Lowfinger,

    I need your help!.
    My MCI500 have lost its left speaker. When opening the unit I found that the glue around the capacitors have turned brown due to leaking capacitors??? My plan is to replace the myself. Do you think this will solve my problems?

    What are the grey components behind the capacitors marked "330" ? Do you think they needs to be replaced aswell?

    Here is a link to the photo: http://www.ladda-upp.se/bilder/qknullvhfjmmtz/

    Thanx in advace!

    1. Hello Lasse,

      the black glue you can see is normal and not leaking from the capacitors, it is to reduce mechanical oscillation of those components. The capacitors (and inductors, marked 330) will be fine.

      I have seen two issues causing loss of sound. Blown amplifier chip, (NXP tda8932) I have successfully fixed several units with blown amp chips. The other is muting from the headphone jack, insert a jack in and out of the headphone connector and see if that makes any difference.

    2. Hi again and thank you for the very fast answer :)

      I have now tried to insert a jack in and out to the headphone connector whithout any succsses. I even tried to disconnected the cable from the headphone jack. This leaves me thinking that your suggestion regarding the amplifier chip is next on my troubleshooting list, but I need som additional help. Where do I find this chip in the MCI500 and do you have the possability to provide me with such an amplifier chip? (or is it some kind of "basic" part that I am supposed to find in a well-stocked store?)

      Once again - thanx a lot for your help !

      Regards/ Lasse

      Delete
    3. ...please notice that only the left channel (speaker) is out of order...

      Delete
    4. Hi Lasse,

      your welcome. The chips (there is one for each speaker) are under the black heatsink on the board you took the photo of.

      You can trace back from the speaker connector to the chip for that channel. Experience with surface mount soldering required.Obviously no guarantee it is the chip but for £6 worth a try.

      Possible to swap the two chips around if your de soldering skills are good but for the price and if you can wait I would get a new chip.

      The best place to purchase the chips is ebay. The chip in the unit is a TDA8932BT, I replaced with a TDA8932T.

      Regards,

      Delete
  40. Today when I started the unit, the left speaker was dead but after a while it started to come music through the speaker. After another 10-15 seconds it was fading away again. Any suggestions what that could be? A bad soldering somewhere or could it still be a bad amplifier chip? Troubleshooting tips wanted :)

    Merry Christmas to you !

  41. Intermittent sound from the chip makes a faulty amp chip significantly less likely. Each amp chip has its own +30v supply, measure this on connector 1109, pin 1 = 30v amp1, pin 5 = 30v amp2, 2,3 & 4 are ground. Check this voltage to each chip.Good luck and have a happy christmas !

  42. Hi Lowfinger. I've seen your impressive posts. I have absolute no clue about electronics. I'm a typical mechanical guy. I've a Philips MCI500 with the same types of problems. When connected to the power grid the power button is just bright red. When disconnected and connected rapidly from the power grid a couple of times the button starts to flash. When disconnected again it keeps flashing for about 10 seconds and fades out. Everything else, but the CD-drive which is spinning up when unit is powered, is absolutely dead I'd hate to discard it because the problem probably is a 10 pence component. What would it cost me to bother you taking a look at the PSU? Best regards Peter, from Denmark

  45. hello,
    I have a problem with a radio WACS 7500 (very close to the building MCI500 radio) I recovered: I have no sound on the speakers; I, however, well sound through the headphones when I plug the plug into the jack.

    do you know whence can the problem?

    when I dismounted, I've realized that the fan intake and subwoofer jack had been reversed (probably not via a predecessor attempted repair ....), I returned to normal without success : (:

    Is that incorrect handling could toast the power amp section (TDA 8932BT)? to something else?

    thank you for your help (I was able to repair the supply part in great part thanks to your help:-))

    best regards,

  49. Hi Lowfinger,

    I have the same problem as described many times.The problem occured after a power shortage: When the power is plugged in, the display flashes white and the power button flashes red. It can't be turned on. Harddrive sounds like they are turning.

    Besides some Brown markings around the copper readiator there are no visual detects.

    Are you willing to repair it?

    1. Thank you very much, all these components are burned then I will see if it will fix the problem but I'm not very optimistic. How can I check voltages on connectors? Have you details on pins?

      Delete
    2. Hi Julie,

      there is a manual to download here that gives voltages on connectors.

      http://elektrotanya.com/philips_mci500h.pdf/download.html

      In brief though, the molex connectors to the hdd and cd should both have 12v and 5v on them (middle two pins are ground). On the other smaller connectors if you measure every pin you should see somewhere, +5v, +12v, +9v and +30v, if they are all there things are looking good. These should all be present with no load / running it on the bench not fitted to the Streamium.

      Having repaired several with the components you list blown I would carefully check the SMPS driver chip that drives the mosfet that died, all diodes relating to that driver / mosfet. Good luck with it.

  58. Hello Lowfinger,
    I will tell something about my troubleshooting. I don't known why, but my measurements at the first step are wrong.
    All Voltages are ready exept the 9V ECO. So I measured at the PCB and there is been a mishap.
    I came out with the test prod. After that the ICE3B0565 and the ZD004 were definitely dead.
    I replaced both but it didn't work.
    I drew the complete secundary side of the 9V ECO. That takes many time and I found a harmless methode to check the function of this.
    But the problem was, I used a ZD with 18V. I measured the VCC at the ICE3B0565 = 17,64V.
    (Be careful if someone do that. I soldered 2 wires at the points without any power and after that I connect the measuring instrument and then I switch it on. So I don't must touch anything ( DC=308V!!!).
    Then I read the decription of the ICE3B0565. The VCC must be over 18V otherwise it don't starts.
    It's very importend that the voltage of the ZD004 is greater than 18V. I used for that a diode with 22V and than it works.

  64. Hello Lowfinger and everybody

    I have a streamium mci8080/12 with a ps131-300-G0 PSU. The mci is dead, only the fan is spinning.
    So I checked the connectors first. I can measure Following volages at the connectors from above to bottom:
    CON2(30V,0V,0V,30V) CON5(5V,0V,12V,0V,9V) CON1(12V,0V,0V,0V,5V,9V,2V,0V,2V).
    So every voltage level seems to be available.
    Is there a connector which should have another voltage? Thank you very much for your help!

  65. Hello Lowfinger,
    congratulations, your blog is fantastic.
    I already repaired my MCi500H once, replacing all capacitors on the PSU.
    It worked, until last week, after a power failure. Now I only get the Philips-screen (seems to be a boot-loop). The voltages 30, 12, 5 and 9V are all present. Should I retry to replace all caps?
    Have you any suggestion?

    ReplyDelete

    1. Cheers, a boot loop can be caused by a disconnected HDD, CD drive or wireless card, check they are all plugged in ok, I have come across a failed CD drive, the drive seemed fine and was plugged in ok but was in boot loop, swapped the CD drive and all ok, maybe try an old PC IDE CDROM drive if you have on to hand. It does sound like all voltages are ok.

    1. Hi Peter,

      IC101 is a TL3845P, if it is blown there is a good chance that Q002 5n60c mosfet is blown also, possibly the input bridge rectifier and fuse, check all diodes on this switching circuit and the high power resistors for open circuit too. Good luck.

  83. Hi,

    My mci500h has an intermittent speaker channel - sound occasionally coming back through the channel for 5 seconds or so and then cutting off again. Swapped speakers and it is the same port that is dropping. Working fine through the headphone jack.

    Does this sound like a PSU issue to you? I assume it's unlikely to be the amp chip as it's intermittent (but mostly not working).

    Thanks
    Chris

    ReplyDelete
  84. Hi Chris,

    the ones I have seen with speaker problems on one channel have been related to the headphone jack muting. Try inserting and removing a jack plug many times when the fault is present and see if it influences the issue at all.

    It does sound like you may have tried that to some degree.

    I have not seen the common PSU issues influence the sound, the two amplifier chips each have their own 30v supply, it is not impossible that one supply is bad but I have only seen less common issues affect both supplies.

  85. Hi all, same problem here with a MCI500H, red flashing power led. Replaced all capacitors on the PSU. That fixes the problem for me. A german online store sells replacement capacitor specially for the PSU. Search for "kingwall ps131-300"

  86. Hi Lowfinger,

    I'm another MCI500H user with faulty PSU.... :-(
    Device is almost totally dead. No screen flashing, etc. Power btn is red but it switches to green after pressing.
    Voltages are:
    CON1 (1008): 0, 0, 0, 0, 0, 9.0, 2.9, 3.1, 0
    CON2 (1009): 7.8, 0, 0, 0, 7.8
    CON3, CON4 (DVD,HDD): 0,0,0,0
    CON5: 0, 0, 0, 0, 9

    I can hear strange buzz from one of transformers (not h 50Hz buzz, its around 5Hz)

    I already replaced all electrolytic capacitors, but without luck :(

    Any ideas what I should replace next?

    Thanks in advance,

    1. Hi, input fuse, bridge and 9v eco circuit look ok but you are missing the dual 30v for the amp, 12v and 5v for the drives. So the ICE3B switching chip looks ok (the one with the brass heatsink mounted on top) but one or both of the TL3845 switching IC's has a problem, check the mosfets on the heatsink that these chips drive for shorts, the chips themselves, also all diodes associated with these IC's. Also check the high wattage resistors that are in heat shrink for open circuit.
      Good luck.

      I replaced both TL3845 and 5n60c.

  98. Hiya Lowfinger,
    I've had a defective Philips WAC 700 for months now that wouldn't boot anymore. Never found the reason for that until I got the chance to buy a used second WAC 700. That's a used device that produces an oscillating sound as soon as it's connected to the mains. After cross-changing parts of the two WAC 700 I finally think they're both having defective power units (3141 078 00211). I have opended both power units, but I haven't found anything obvious like defective capacitors or burn marks.
    Have you got the time and energy to look at those power units or can you explain how to check the units systematically, please?

  107. Hi Lowfinger!

    Are you still offering repair services for these? My friend has asked me to look at their MCi500H/05 which is dead when you try to power it up. They have actually asked if it's possible to retrieve the songs from the hard disk rather than repair the unit, but from what I found out it may be simplest to repair first and then copy if all the song information is to travel with the mp3 files. Anyway I have helped people with their PC's before but with this one I am out of my depth - if you are able to have a look please email me rewarbalert@googlemail.com Rew Francis

  108. hello all, my MCI500H is dead, know how to read the hard disk directly on PC? At Home I unable to read it. An idea? A solution? It's possible. How to recover all my music ?

    ReplyDelete
  109. Solved so if you want to recover all your music and read the mci500h on your pc you must do this:
    Install a linux distribution (ubuntu, pclos, arch ....)
    When you connect your hdd you can not acces.
    Open a terminal (my partition is hdj6)
    use this commande:
    sudo fsck /dev/sdj6
    you have this message:
    fsck from util-linux 2.27.1
    e2fsck 1.42.13 (17-May-2015)
    /dev/sdh6: recovering journal
    /dev/sdh6 contains a file system with errors, check forced.
    Pass 1: Checking inodes, blocks, and sizes
    Pass 2: Checking directory structure
    Pass 3: Checking directory connectivity
    Pass 4: Checking reference counts
    Pass 5: Checking group summary information
    /dev/sdh6: 3477/19251200 files (21.5% non-contiguous), 3457693/38483699 blocks

    then use this commande:
    sudo e2fsck -f /dev/sdj6
    use yes to rewrite.... and YES I can read my hard drive!

    1. Great, good info and glad you got sorted. The disk can also be accessed within Windows from some disk tools such as Winhex or Restorer ultimate. If you want your MCI500h repaired just drop me a line. Also if you were considering throwing it away I would be interested in it for parts !

  110. Would that window access allow me to restore the systems operating files I upgraded with the wrong system firmware some time ago and it never worked since

  111. If the 'firmware' has written to flash memory on the main board then probably not, if it has just made a mess of what is on the HDD then I have a disk image of a working system you can use. Drop me an email if you want to give it a try.

    1. I'm not sure to be honest unfortunately I think the firmware completed really frustrating as it worked fine untill I did it, the dangers of amatuer !

  112. Hello,
    i just moved my MCi500H to a new location. I had it just plugged in and turned of for a long time, but when i moved it, the stereo system wasnt turning on. So i opened it and looked at the power adapter and saw a black marker on there. seems like one or two component went to heaven.
    Is there any possibility to get it fixxed or buy a new power supply?
    I hope that you will answer me soon, because its a very nice stereo system. I would like to get it back working again.

    Thanks for everything and have a nice day,
    Heenne

  116. Hi,
    i've been repairing one of these for a friend. The unit did not power on. I managed to find a donor unit with a working PSU on ebay. The unit now powers on but the display has no text or menu options. I think the the file system may have been coruupted during the PSU failure. Would you be able to supply me with an image of a working unit that I could write to a new HDD. Some idea of cost involved would be useful as well.
    Thanks

    1. Perhaps I should also have added that the device cannot be seen on the network and cannot be connected to via the Phillips Software.
      I have also done a resetto the system, but nothing changes.

  117. Hi lowfinger
    I have an mci500h/05 that has a blank screen and is making noises and I can hear the fan, can you have a look please and what is your address so I can send it to you.
    My email is ralphb0222@gmail.com
    Thank you.

  118. Glad to hear you are further on. I would say it sounds like some dry joint or failing component on your RH amp circuit, if it is 5017 (inductor?) I would say swap it with the one fron the LH amp circut and see what happens. The D class amp chips are quite fussy, there are a lot of small SMD component that must be just right to run the amp. Failing that change the amp chip. Good luck.

    1. Thanks Low Finger !
      So, right now, I am a bit confused : as you suggested to swap Left & Right, I've just begun to swap 30v +Amp_1 with +Amp_2 (pin 1 & 5 on the 1109 connector). As a result, there's no more trouble with any of the speakers !? Maybe some component from right AMP can no more do filtering or protect correctly an random power coming from SMPS, but left AMP components can do it better ? Pretty strange, no ? Anyway, the good news is that my MCI500h is working again...

  122. Hi Lowfinger,
    I did a Firmware RESET on my MCI500H/05 and it has been able to reboot since. The standby button goes green for 20 secs when connected to power then goes red for a split of second. It does not even respond to any push on the standby button.
    Do you have any idea why that is? It was working fine before the Firmware Reset.
    Thanks
    Mamadou

      My unit seems to have the same problem, although I never tried a Firmware Reset. Please let me know if you find anything out. How did you do the reset?

    1. Hi Ian, unfortunately there is no circuit diagram available that I know of for the power supply.

    2. Incidently can you give me any pointers as to the voltages on the pcb to make it any easier to locate which area I should be looking at.

      Delete
    3. Hi Ian, the MCI500 manual on Elektrotanya can help with what voltages should be there but basically on the black cables you should have a 5v,9v,12v&30v.

  127. Thanks anyway, just have to keep working through it. Surprisingly all the electrolytics appear ok.
