My dvd rom drive ejects and closes erratically. I have a v1.0 that is not modded in any way. I have swapped all parts except the motherboard to troubleshoot the issue. I have narrowed the fault to be in the motherboard. Is there a part on the motherboard that I can swap to test further? Any help would be greatly appreciated.

Is it a VAD6011 Philips? If so, the controller IC on the chip is shot, either get a new board out of another 6011 or get a new drive.

Sorry, the dvd drive is a Thomson. I swapped the drive with a known good one, and it still does it. I believe it to be on the motherboard. Since my original post I have been studying pinouts and diagrams trying to isolate the fault on the board itself. I have been trying to get detailed info on how an eject command is processed through the motherboard. (i.e. Pic pin #s, resistors, collectors, etc.)
So far, not much luck. Thank you for your assistance.

Hi,

probably a damaged trace or broken resistor on the signals on the mobo coming from the P/E board. This site should help you investigate that further:

Could well be the PIC16LC63A chip on the mobo, follow the test proceedure here to verify:
