All of the ebay adverts for screens advised to remove the faulty screen first to get the part number. There are several types and a visual check is the only way to be sure.
There is a good video on youtube.
Unclip the front panel and undo the two screws
So here was the screen out. Part number identified in oval,007/111 in this case. (The screen is upside shown upside down from when it is plugged in) Two circles show screws to remove screen.
A new front panel was also fitted, this is very simple and will make the phone look like new !
Replacement screen was fine.
