The spindle will not spin if the optics are unable to achieve focus. ldfan wrote: As for the fish smell Cplusplus mentioned, can you confirm the inside of your player has that odor? It has been a while since I was working on it, but I think I still have it somewhere. It was definitely the bad electrolytic smell. I think I remember the spindle having issues. I later discovered some spindles have three electrolytic capacitors inside the metal housing, so I'm not sure if it was coming from there or the power supply. I'll dig it out and make a post if there is anything interesting going on.

It still won't play a disc.
Can someone tell me if the LED, next to the laser assembly should always be lit, even when you just turn the power on?
I don't see any light coming from the LED at all.
What is it supposed to do?
Thanks,
Maxx The LED next to the laser is the tilt sensor, no it should not be lit. The laser will only be lit when the lens is moving up to try to get a return signal off the disc, if the electronics does not receive a return to signal a disc has been inserted it stops there. Spinning only occurs after a disc is verified as inserted and then the unit advances to the next step to spin the disc, turn on the laser, focus on the disc, and read the table of contents. You are not getting a return from the laser so it will not try to spin as it thinks no disc is inserted. Either the laser is bad or the drive electronics are bad. If you have an oscilloscope then you can connect it to the power line for the laser so see if the electronics sends a pulse to for disc detection, you'll have to have the oscilloscope setup to trigger on a pulse detection.
