Question about Sony CDP-C505 5-Disc CD Changer

1 Answer

Put in clean commercial disc and get error msg "no disc" period!

This is a SONY model CDP-491 single disc player purchased in June 1961. It was working fine these 20 years - enjoyed - not abused. Played a disc fine a week ago, tried to play the next day and got the
error message "no disc", and same message since. Doesn't play. Read & tried the on-line suggestions with no luck.

I am an OLD audiofil - designed and built equipment since I was 15 years, a radio amateur, TV teacher and engineer, etc. am now 89!

Please give me a clue...

Dr. OM,

Lets give it a try. The purchasedate will be 1991 (HI).
I'll suppose you allready cleaned the laserunit.
You can try to clean the laserslides, sometimes they are sticky and dry. Then the laser is not fast and precise enough to read the index of your CD.
Clean them with some alcohol on cottontips.
When they are really clean, use just a little teflonoil to make sure the laserunit slides very smoothly.

Regards,
73's Gerard

The sony model #CDP-c910 skips discs continually and does not stop to play a disc. Am interested in repairing this set or purchasing a new identical set if it is still available. The size is...


Try changing the (only) belt the player has with a brand new one. Go to www.partstore.com. I believe it costs more than $10. Clean the pulleys with isoprophyll alcohol using a cotton swab after removing the old belt.
After you remove the top cover, take a careful look how the belt is placed. Don't unscrew anything. The belt can be removed and replaced without removing any screw. A paper clip will help if you don't have the right belt removal & replacement tool. A commercial CD lens cleaner (I use Scotch brand) will greatly help. Just insert it in your magazine and run for a few seconds to a minute. This is not a sure fire solution but most of the problems in this model is attributed to an loose/overstretched old belt and a dirty laser lens. I hope this helps & good luck!

Cds dont load and tracks will skip during song play


It is clear symptoms of bad optical laser or dirty optical lens.
Please put lens cleaning CD in player, play that CD to clean dust on optical lens surface. If that helps, fine or replace optical laser block in player.
I can provide you optical lens part number, please confirm is it Sony CDP-CX153 cd player or any other model.
Thanks.

Rotary table on Sony CDP-CX225 200 disc changer will not rotate


I think CD Mechanism needs service and might required belts replacement.
You need to get service manual of your CDX-C225 model to do this job as manual contains all technical info about mechanism etc.
