Harman Kardon FL8350 CD Changer

CD Changer CHA-S604 does not read MP3 discs. Alpine CD Changer CHA-S634 reads MP3 discs only.

Welcome to Fixya

Try to use cd cleaner first to clean the lens. Its giving you a BAD CD error because the lens cannot read the disc. Do the cleaning method 2 times.

Please reply to this email for any update.

IF THESE ERROR CODES STILL KEEP APPEARING
CONTACT YOUR DEALER.

Ha! I read the directions! The discs are supposed to be upside down! Problem solved :)

cds skip irrespective of their positions as the reading lens is the same for all.
you can do the following
1)this seems to be a SERVICING problem with dust playing the spoilsport.
OR
2)buy a new disc (scratchless) , play it in all positions and com pare.

if it skips in all positions, call an electronic engineer who will replace /repair the delay circuit.

There is a rubber belt inside the loading mechanism, you should replace it by the new one. Cleaning the optical unit can be of great help also. If you need more info, please advice.

Common Problem with AIWA 3 disc machines. I have 3 in my service shop right now. For tray not rolling in on it's own, the drive rollers have to be changed, along with the Drive Belt. Also, for CD not reading, try CD lens cleaner.
