CD players says "NO DISC"

[menschenstimme]

When I load a CD into my player is says 'NO DISC'. Is this more likely to be the laser (which I can see doing its normal flash of light when the disc loads) or might it be the circuit board that drives the transport?

It's time to get a new player!

Thank you for your suggestion, but that was not my question. This is a very special player and I prefer to repair it if possible. I have a spare laser for it. I just have this strange feeling that it is not the laser, but rather the circuit board that is part of the transport assembly.

It is my hope that someone will comment in this regard.

Thanks again!

First, put in the spare laser that you have. If that doesn't work, then send it out for repair.

Blow some canned air in there to make sure its not just stray debris in the laser path. Also try multiple CDs and jiggle them around to make sure they're properly seated. Could also mean the tray isn't positioning properly (assuming its one that slides in and out. For me no disk is usually means that the tray or the disk isn't quite in position; a couple taps and jiggles usually works.

Many thanks to all !

I cleaned the old laser and then gave up and installed the new laser. I cannot believe that I did not destroy the entire transport in the process! LOL! At first the "new" transport did not want to read the disc - the motor would not spin - then it spun wildly - it was crazy. After several tries, it settled down and is now playing the CD. I am almost afraid to turn it off and on again. The entire experience was a female canine! LOL!!

Thanks again!

Well - I regret to say that things have gone awry. The new laser is still working fine, but the motor started not starting unless I manually prodded the top of the disc clamp to get it going. Once going, it would play nonstop as long as I wished. However, once stopped, whether still warmed up or stone cold, the motor would not start again without a push of the finger on the disc clamp.

So, I lubricated the motor and now it is totally dead. So, what I would really like now is to have some speculations from the group mind regarding the following question:

I had to take the transport partially apart to lubricate the motor. I think that I simply destroyed the motor by lubricating it. It will not even twitch. However, statistically speaking, how likely is it that I caused an electrical problem of some sort that is causing the player's control circuitry to not send power to the motor? I think this unlikely, but I would appreciate hearing from those with more experience than I have.

This is all emperical for me - I have no testing equipment to check current flow to the motor, etc.

Thank you for the courtesy of your patience and understanding!

You might get a kick out of this as I ran into same problem couple of years ago:

Well, I did indeed find this part of your thread very amusing:

WTF???
