HP Officejet 6500 E709a Series dead faulty PSU 0957 2271
A HP Officejet 6500 E709a printer had a dead / faulty PSU. Printer would not power on and no light on the power supply.
Opened up, nothing obvious to see. A check of all the discretes showed the diode circled was short. Out of circuit it still measured dead short.
A VSB3200 was the culprit, a 300v 2A Schotcky rectifier.
(picture shows new diode fitted and dead one out)
Tested working ok !
