Sharp Aquos LC-46X20E repair help request.

[godofwap]

ok, my lc-46x20e started turning off and on by itself and a few days later it wouldnt boot up, i was getting the 2 x power 3 x opc error code, which as i understand is telling me that the IC2002 chip is not receiving the 10v necessary on pin 57 which in turn controls the boot up sequence, now, i've changed the power board and "sub power board" but when i try to get into service mode using the procedure outlined in the service manual for that model to do a reset, i get the same error code and it wont boot into service mode, no K appears on the screen, the replacement boards are 100% working and now i'm stuck on what to try next, any help would be very much appreciated :-)

It would help if you could supply pictures of the chassis layout.

Hi same Problem her. I changed the power supplies. Same error code. Can I pull off other components from the power supply, to check voltages?
