About three months back My MDP-650 started not playing discs on command and instead displaying the "OFF" error message on screen. When this occurs there is a slight straining noise like the disc is trying to start spinning but there is something physically obstructing it. So I got some time today and took the cover off and messed around with the clamps, cleaned them etc, no fix. I now find that a light push on the edge of the disc after I press play gets the disc to spin up and play as normal. When I do this it feels like there is some release of pressure and the disc spins freely. I recorded a couple of (sorry upside down) videos of the problem: Video 1: OFF errorVideo 2: light push "fix"Would anyone have an idea of what might be catching or holding the disc back initially? It seems like it should be an easy fix but I can't figure it out. There is nothing physical touching the disc except the clamp. Thank you.

Sounds like you're SOL and I'm not talking about the satellite from AKIRA. Have you looked for a service manual?? This is the problem when owning an off brand, you may think its great but when they go they go hard and you have nobody to help out

If its such an easy fix why are you asking how to fix it Nobody is posting about how to repair then that means your player is an off brand and there aren't enough people who know how to fix non popular brands of players. As for the service manual, it could help you with trouble shooting, try and find one to see if you can fix it yourself.

If you want to work on LD players, the service manual is not just your best friend, it's an indispensable guide. These machines are complex enough that even a very experienced electronics service tech can do little without extensive documentation. It's not shameful if this is not for you.

No, its not shameful at all if you don't want to deal with the service manual but there is a reason for it as you have posted publius. And from his post above its more an attitude of what will it matter to use the manual.

Here is the service manual for the MDP-650: http://manuals.lddb.com/LD_Players/Sony/MDP/There are 2 of them so select whichever. I have not inspected the two to see if there is any difference. I will leave that up to you. (I have downloaded the SM for my MDP-600 just to have it. You never know when an "off-brand" player could die.)
