Hi you could try cleaning the laser lense with dust free cloth but soft one if this dont work try cleaning your cd you can run it under cold water tap and then dry with soft cloth make sure their is no scratches on disk surface if this still dont solve problem then you find the laser itself needs replacing.
But the problem with this is replacing the laser and getting it calibrated will cost more than a new stereo thats why knowbody repairs these kind of problems let me know if you need further assistance

Have jwin cd player with am/fm radio cd player don't work


The problem is in the Laser Pickup Assembly, the only solution is to clean the laser lens gently with a Q-Tip and rubbing alcohol, if this fails there is no other option but to replace the whole assembly "not cost effective" or buy a new player.

CD Player does not turn


Hello,

how long have you been using this player and when did this begin?

Remove the disc and try another. If the player refuses to eject the disc, remove it from the wall and fix it back and fix it back again. Then turn the player on.

If the player still gets stuck on "loading" mode for other disc, then it means the laser is weak.

The lens is weak such that it cannot load data on discs. Its spinning, trying to load, but can't because of the weak laser.

Get a lens cleaner, use it to clean the lens. If that doesn't solve the problem, get a screw driver, open the player's cover so that you can gain access to the lens, use a cotton board to clean the surface of the lens. This should clean dust or dirt that might be on the lens.

If non of the above solves the problem, then know that you need to replace the laser to a brand new one.

To replace the lens, remove the bad laser, use it as a sample to get exactly the same type and do the replacement. Note that replacing a laser (lens) needs a professional touch, so if you cannot replace the laser, get it to a repairman to fix it for you.

Once this us done, your player will play all discs again.

Regards.

I have a Sony" Personal Audio System" /boombox.


Hi, this is a pretty common problem with C.D. players, the laser has lost a bit of its intensity. This possibly can be fixed by adjusting a very small " semi-variable resistor " this should be located on the laser assembly or on the ribbon cable just before the laser. It may be a colored plastic dial with an arrow on the top, or a metal looking screw type looking adjustment ( probably has a bit of enamel to lock in place-this breaks free easily). It may even be labeled " bias ". Use a small phillips jewelers type screwdriver for the plastic kind and a slotted jewelers for the metal. move the adjuster in very small increments one way then or the other if need be. Make note of the original position in case you need to adjust different semi-variable resistors. also its even possible to have a dirty lens, use a jewelers loupe or equivalent to check. a very light touch with a Q-tip dipped in rubbing alcohol should do the trick. use opposite end to dry, be sure to not apply excessive pressure-the lenses suspension is extremely delicate. I hope this was useful-let me know if so or even if not so I may try again. Thanks for asking FixYa-good luck, Prodzilla

I have a sony CFD-S01 which will play commercial cd's but when a cd-r is inserted it either won't recognize the disk or it jumps constantly after appros 10 sec, any ideas?


The CFD-S01 is designed for use with CD-R and CD-RW discs. With that in mind a few things come to mind. Are the CD-R discs you are using music or data discs? There is a difference and some CD players do not get along with data discs and won't play them well if at all. Also the burn rate used can have an effect - too fast and it won't play well. If a disc doesn't play at all it might not be finalized. A disc must be finalized on the recorder it was burned on before it is playable on any other machine.

Car CD player ER message, then reject ???


when you get an err message it means that the eye of the cd cannot read the disk. when was the last time you put in a cd cleaner? one that you put into any cd player. you can get one at your local big lots or radio shack or best buy. you need not spend a lot of money for one. or you can try to use a cuetip dipped in alcohol and clean the eye only. dry with another cuetip or soft cloth and see if that solves the problem.

My CFD-Z501 won't play a disc. I get the message "no disc"


Try to use CD/DVD clening disk ($6 in Walmart). Or simply use cotton swab (Q-TIP) and 40 % ethyl alcohol (vodka) or 50-70% isopropyl alcohol (NO ACETONE), depending on your budget.
Also check if discs are inserted correctly and not damaged/durty etc. Also check your discs. Some CD-players dont accept burned CDs (copyed). I believe Sony is not the case, just a suggestion.
If cleaning wont help lens might be damaged.
Good Luck
