The ribbon cables are both fine. i think the problem is in the mechanism with the sprockets. Luckily i have a spare boombox So i first try a new mechanism.

OK, I've never seen this problem before. Can you try one more thing? Gently move the laser sled to the far end of its travel, then put on a CD and press the TOC switch. If the motors are OK, the sled should move back to the inside of the CD and hunt around a bit as it reads the TOC.

Very odd problem!

I think thats Ok.

I just checked mine there now and it does the same thing. Then the laser "rests" a little bit out from the start. When I then press play, it jumps back a little, then more slowly moves to the inside of the CD and start to play.

By any chance have you separated the controller board from the mechanism? I ask because the other thing that could be wrong is if the sled is hitting the stop switch at the wrong place. People who separated the board from mechanism had to add a pin to the sled so that it still contacted the switch. If that was out of alignment that could cause the problem.

The image below might help maybe in tracing the fault?

Yes, i have separated the controller board from the mechanism.
The pin from the sled was moveable because the glue was dried out and i fixed this. I have moved the controller board many times for making the right contact to the switch, but without succes...

I have 3 new mechanism from ebay with the sled fixed to the mechanism. So that problem is solved. Im waiting for the longer ribbon cable for the mechanism.

So we should be able to use drivers to interface to other displays. Great. Is that an LCD display?
