Eject issue - tray won't open, eject not respond

[sidocious]

Hi Friends,

I'm here to ask your help again.

My friend ask me to repair his xbox. When I opened it I seen the following.

Xbox 1.6 with an MSI DVD/DVD RW drive. The dvd drive was soldered to the eject button's board. I do not know this type of DVD MOD cause I always use LG 8163B drive.

So the plan was the following. Soldering in an Aladdin XT modchip and change this unknown DVD mod to other --> LG 8163B (it was tested in some other xboxes and worked well) and change the HDD to a bigger one.

Okay, chip soldered in, works well. DVD drive changed to 8163B, and here is my problem, the eject button won't work. I can open the DVD tray only with the eject button of the 8163B. I not tested the eject button before the changes.

I checked the traces on the motherborad with multimeter, everythings fine. I checked the Poweron/Eject board, there is no problem with it.

So, if someone has any idea what I have to try to fix it, that would be great.

Thank you in advance.

Can you post some pictures of the mod for the MSI DVD drive?

Verify with a multimeter that the eject signal connected from the Xbox to the LG 8163B drive is actually changing state when the front panel button is pressed.

MSI DVD is not important, but your idea was the key of the solution.

The guy who made that "MSI" mod, pulled out the eject pin from the power on/eject board's (pin4) and put it back to the empty pin (pin10). So I rebuild it and than now works well.

BIG Thank you again!
