SOURCE: cd skips

If the unit continues to skip after cleanig the lens using a cotton swab and alcohol, the optics are failing and need to be replaced. These units use Sony optics (KSS-213C I think) and are readily available for $25 or so. Any service shop should be able to replace this for under $100 total.

I had a rca system similar to this little different. It's a problem you'll find in any cd player after awhile. You'll need to replace the laser. It's quite easy google for some instructions to replace a cd laser. Look around for a laser that can read cd's and cd r and cd rw and you'll be ok. The disassembling might be a bit tuff but it's worth it. I had to replace my hifi laser and after i did sound was incredible again no skipping. Make sure when opening your system you power it on and unplug it to make sure all charge is gone wait 30 minutes or so before you go and operate.

Hi ..I have Pionner PD-M701 CD Chanager .the player works so fine and recognize all cds in the trays but the issue is in the reading .

hi Sam.
you could try this.
Clean the CD if it skips or the player can't read it. Use a clean lint-free cotton cloth and make sure the CD is not scratched. Use a lens-cleaning CD in the player. If you can access the lens without opening the case, clean it with a cotton swab and lens cleaner.
Why does a CD player skip? They don't scratch as easily as vinyl LPs, but I've damaged half a dozen CDs over the years. If a CD is skipping, first give it good clean using a CD wipe or mild soap and water. Dry carefully with a lint-free cloth in a straight line from the centre to the edge. Rubbing in circles can cause more damage.

Cds won't play

OK, your discription of your problem is rather vague.

Do they try to play but skip or make god awful noises? Or do you have no audio at all?

If they are skipping check to make sure there are no smudges on the underside of the CD. If so clean them with a soft cloth,

Sometimes severe scratches can cas the same problem. You can buff out some scratched using tooth paste or you can by a scratch remover that they sell in stores (it is a gadget that will clean and buff out some scratches available in many stores).

If you have any of the label missing then this is a worse issue. It is actually the top of a CD that you need to be most careful about scratching because if you remove the laquer that protects the silver layer of the CD it will remove part of the silver with it along with any audio or data that is on it. There is no repair for this.

If you have ruled out a damaged or dirty CD then be sure you are not trying to play a CD that has data files intended for computers on a player that cannot open them. The best way to do this is to check the CD on a computer and open the drive folder and view the contents of the disk. Files such as MP3, WAV, WMA and others will not play on a standard CD player. If the files are CDA that is a standard audio CD formatting. So next see if the disk plays on the computer.

If the CD plays on a computer then return to the CD player and attemp playing again. Make sure that the player recognizes the CD being in the tray. Also, verify, if you can that the CD is spinning within the player when you play. If the CD is not spinning or the player does not recognize rge disk try a disk you know to be undamaged.

If you still have problems then you will have to have your player repaired or replace it.

Technics SC -HD 501 CD jumping and skipping

If this happens on all CDs then most like the drive is bad or lens is dirty You can try cleaning out the heads using a cleaner disc. If you have a way to get to the lens you can try cleaning it manually. But most likely. It's one of the following dirty lens, bad motor, bad speed control.

Its time to replace the optical unit ( lens ) of the CD player. Brace yourself the unit on some of those old players can cost more than a new DVD player.

It's possible the laser assembly got damaged or dirty.. Inside the back cover of your users manual is a procedure to protect against that. Trying to clean the laser yourself would possibly lead to more damage as they are protected from view even when the units outer cover are off. I no longer actively repair electronics, but I can tell you a repair costs more after a customer attempt at correction than the original failure. Lasers are finely positioned mechanisms. I would suggest professional service.

yes here is a simple easy way to get them to stop skipping, stick them in the freezer portion of your fridge, only if the cds have scratches on them, even the smallest scratch can cause a perfectly working cd player to make the cd skip, stick the cd in the freezer for about 15 or 20 mins and pull it out and play it, i have used this method for a lot of my video games as well and have never had to buy any "cd player cleaner cds" i hope this helps
