I have a 2 in 1 VHS/DVD player. It is a GO VIDEO DV1130. When I press the eject button, nothing happens. The tray doesn't budge. I currently have a DVD in the machine as we speak. The DVD itself works perfectly. I can play, pause, FF/RW.....etc. The only thing it will not let me do is eject the DVD. The last time this incident happened, I tried a little trick, which ended up working perfectly. However, the same attempt didn't work this time around.

Sounds like you've got a problem with either the Drive Motor, Drive Controller or Drive Belt.

It could be an easy fix but it depends on the where the fault is.

Does it make any noise or effort to open the tray?

If yes then its the Drive Belt thats either slipping or broken.

If you remove the top cover and then the cover off the DVD you'll see the drive belt at the front. If it's still in one piece then you can just remove it and get one a few mm smaller.
