If possible, I need this to work because it plays DivX files.

Any suggestions? Should I try to clean the head?

One longshot possibility, on those, there are one or two electrolytics in
the power supply that are very common to go bad.

Normally the failure causes the unit not to turn on or shut itself off
after it's on and loading the disc (current draw from the tray motor).

If the unit never had them replaced, it's a cheap and easy fix.

It might help. Google for like "dvp642 capacitor".
