David if you cover the led and the motion stops that tells you that the led is working. I would be looking at the end sensors being bad first. Probably the supply side but I would replace them both.

If I press the "ON/OFF" button the TV goes off, the motion stops, but then the tray starts to move back and forth again, when it moves forward the TV powers up. If I place my finger over the cassette sensor, this motion stops and I'm able to turn the TV "ON" and "OFF" but as soon as I remove my finger the whole thing starts to act up again. I'm thinking maybe the sensor LED is not working and I'm in the process of taking this unit apart. If anyone has seen this problem before or if anyone has a schematic to share I would greatly appreciate the help.
