CLD-D503 says No Disk

I have a Pioneer CLD-503 that I have not used in a few years because all my TVs have HDMI input so I recently purchased a converter to make the work.
I was all excited to see some of my old LaserDiscs. Real quick after several different disk attempts it just keeps coming up with no disk.
I blew out the little dust that was in it and cleaned the laser lens. No luck.
I understand that the laser needs to be a specific distance from the disk to recognize it is there.

I can see that the laser comes on and tries to find the disk. Any suggestions?

Thanks to all in advance,

Wayne Torrens

Check and see if it will play a music CD. All the sync signals are processed differently for CD playback. If it won't then it will most likely be the laser assembly or maybe the powr supply.

Sorry, I should have mentioned that I have tried both already.
I can see that the laser is coming on when it is searching for the disk.
Is it that the laser can not see the disk or is there some other sensor.
I read one post where someone said the distance between the laser and the disk could be adjusted because it could be drooping over time.
Thanks for you feedback,
Wayne

You are seeing the laser move up and down so distrance between the laser and the disc is not an issue. The servo is working to move it up and down and with the newer laserdisc players the electronics handle the height and what you are experiencing is that no matter the height the laser is not getting a reflection back or the reflection is there and the electronics to read the signal are bad. The electronics is saying it cannot achieve a focus so it assumes no disc is present. To detect a disc there is no other sensor.

Thanks again for your professional knowledge of this issue. Sounds like I am SOL without an experienced service tech who has access to parts. Then again that might cost more than the unit is worth.
If I was to look for another used unit would you suggest any units that may be more reliable than others?
