i just spent quite a few hours trying almost everything i could find out to check why this panel wasnt working.
MB was detecting a fault and going into fault mode.
i could se the AVDD go high for a second then drop to off.
check all CAPs and diodes on bottom buffer boards.
in the end i gave up and removed the panel, only to find burnt tracks on the cof tab..
i learnt a lot in the process, but wont go doing all those checks first next time.
so word of advice... if your panel is suspect, save youself a few hours and check the tabs first.!
