    Compaq C700 No Display

    I got a Compaq C700 ( JBL81, LA-4031P ) laptop without power. Now i fixed the power problem. but no display. I checked all coils having power. But at LCD connector there was no +LCDVDD. Does anyone has solved this kind of problem in your experience ? please give any idea.

    Make sure signal ENAVDD already present, Probably Q7 was faulty.
