Tray will prolly need retimed after the belts slipped off the pulleys. Procedure is with tray brackets removed lift tray in back then push open button to let the cam gear spin around to open position. Then let tray down and try to close it with button. Reinstall brackets and may take a few attempts to get that gear in the right position!

1. Chances are real good that the laser lens has gone out or is too weak to read the disk. It's a maticelous procedure to calibrate a laser lens. It may just need to be replaced. 2. The labored mechanism is due to the belt in the disk drive being dirty or stretched out. With this the mechanism can't inject far enough for the laser assembly to come up properly far enough for a good laser alignment therefore giving you the disk read error. You can clean these drive belts with alchohol and put them back in. While it's out check the belt for cracks. If there are any replace it. Or if it seems stretched out, which you can tell when it's around the pulleys, replace it. This belt is located in the front and under side of the disk drive assembly. I've had the same problem with Xbox360 drives and the above solutions worked out quite well. But I haven't worked on one of these devices yet. 3. As a last thought. There may be a swollen capacitor on one of the circuit boards that may be causing the problem. A cap swells and shorts out. If so it will need to be replaced. I've had single swollen caps keep an entire television from working.

If you have fitted a new laser assembly, have you removed the blob of solder that protects it while fitting, it's on the board underneath across two tracks

You didn't say whether the player is connected by 2 RCA cables (analog) or by digital cable. If by RCA, does the player have a headphone jack? I had a player once with a piece of a headphone that broke off inside the jack, muting the analog outputs.

I usually just clean the belt with alchohol or get a belt from another cdrom. I have yet to find a place to buy belts.

Mine did the same thing after being out of service for several months. I fired it up, ran beautifully for 6mos. Or so, then the "no disc" message appeared. The local I took it to said buy a new one...cheaper than fixing it. Sorry.

You can them from best buyer store on line . The only problem it take two weeks or more to get them

What worked for me was taking the cover off and carefully threading a belt back onto a wheel. There are two motors at the back of the unit, one (I believe) that grabs the discs and moves them in & out of the player, and a second one that rotates the table (i.e., the round slotted thing that holds all the discs). The belt had simply slipped off the wheel that drives the latter. I did remove the back panel as well, to access it better, and inadvertently disconnected a sensor plug, which led to a second round of troubleshooting, but - in the end - I got it working!
