I just got a Technics SL-PJ1 off of ebay for $30 that claimed it was "tested and working." However that was not the case. I temporarily replaced the main drive belt with an O-ring just to see if I could get it to work, cleaned the wormgear, and reseated the laser guide rails, however it never seems to move the laser all the way back in order to read the disc. Whenever the tray is closed with or without a disc, it moves back maybe a centimeter or so before moving back forward and trying to adjust focus.
Just to make sure the reason for this wasn't because of my temporary belt solution, I moved the laser all the way back when I went to clean the wormgear. When I powered it back on it moved all the way to the front, so there wouldn't seem to be an issue with torque. I took a closer look with a flashlight during operation and it does appear that the motor only moves the laser back a bit before reversing direction, so the "belt" isn't slipping.
I have also checked to make sure the back rest switch isn't making contact with itself and it isn't, so that rules out that possibility; and I have cleaned the laser lens, but since when has that ever worked?
Any help would be much appreciated. My biggest fear is that the laser is shot and this is now a hunk of junk.
