No Monitor Output on LCD or DVI
I am attempting to fix a coworker's macbook. It looks like he may have dropped it on the left corner (below the z key). I am unable to get any video from the lcd or dvi output.
This is what I have done so far:
Verified that the hard drive is ok by booting from another mac.
Gone through the disassembly process to check all connections to the display.
Taken the display apart to check that the small boards inside were still intact.
I am still getting what sounds like a proper boot, the normal mac startup noise and some disk reading sounds.
The way I have been checking the DVI is by leaving it plugged in during startup, then closing the lid (external power source, keyboard, and mouse plugged in as well). The mouse is powered by both of the usb ports so I assume those are still working correctly.
Any ideas for further diagnosis?
