iMac No Display, no 4th diagnostic led
HI,
could someone tell me where I can find pinout for espower pwb-iv49151t inverter board please ?
I need to test it as I've just receive replacement screen for my iMac and it's still dead.
symptoms :
-4th diagnostic led not on.
-when dp ribbon disconnected the fans go full blast.
-when all the cables are connected the internal screen is discovered as online by system info and starts with internal as main screen (4th led still off).
-when disconnected from inverter board screen is not discovered.
the Mac works fine with external display.
if anyone have any suggestions I'll be forever grateful.
Seb
