You could try a lens cleaning CD. It is a CD with tiny little brushes on the bottom of it. You listen to a guy say bla...bla...bla...We are now cleaning your player. In 45 seconds it's done. I bought mine at mendard's for less than $20 part of a 2 piece kit which had a lens cleaning CD and a CD scratch cleaner. Here's one for sale on amazon http://www.amazon.com/Memorex-CD-DVD-Player-Laser-Lens-Cleaner/dp/B00008EM7U good luck, Hack

Denon dcd 425 cd player:the tracking mechanism keeps SKIPPING but it SKIPS BACK like the counter will read @ 20 and the next thing you know it has skipped to 14 ??


Hopefully it's just a bit of dust on the lens. Or something inside the unit that is obstructing the mechanism, such as dirt.

The cd player goes into a "skipping" "playing really fast" mode occasionally. Esp. 3rd track, 1st cd. Always has.


It's having trouble reading the CDs. The thing that reads it could be dirty. But try a different cd. The CD player is getting old and if there is even a small scratch it will be hard to read it. A new CD player would be the way to go

Cd player plays for 30 sec than skips to another track or to the end track


This indicates a laser pickup assembly problem, overtime the laser becomes weaker until it cannot track the disc properly causing it to skip, one possible solution is to purchase a cd cleaning kit and follow the instructions and attempt a recovery, if this fails it is cheaper to replace the bookshelf system than have it repaired.

Every CD skips. Seems to skip very badly at the beginning of each track and then about a third of the way through it will play normally. I have put the CD's in the correct way and have cleaned the dust...


The dust has probably got on the lens, which needs to be cleaned too. You can try a lens cleaning disc. But if that doesn't work I would use some Servisol Video 40 on it.

CD SKIPS


  OK.  I think I can help.  There are two very simple solutions to a skipping CD player.  You have tried one already, that is, clean the laser-reading eye.  Lets assume you did that correctly and that is not the problem.         So, to continue, the machine must be opened. Equipment required: Jewellers screwdrivers, small number one screwdrivers, cottonswabs or Q-tips, Petroleum jelly, 100% isopropyl alchohol is ok but if you can use Denatured alchohol that is the best.        Using a set of fine jewelers screwdrivers or just a small #1 Regular or Philips screwdriver to remove the top cover of the CD player.  Don't force anything and place the screws in a cup so they are not lost or misplaced. I work in a plastic cafeteria tray to contain any dropped screws    The problem here usually occurs in trusty old CD players that have always worked fine and the problem (skipping) starts out small and gradually progresses to always skipping.  The problem and solution are mechanical in nature.    First locate the laser eye and check it physically for any optical obstructions (dust, dust-bunnies, lint, feathers, hair, lumber, etc.)    When you are sure the laser-eye is clean find two parallel small (usually 1/8" or about 3mm wide by about 3 to 6 inches long ) chrome metal bars that the laser eye rides back and forth on.  The eye assembly has a small contact-lens looking clear plastic lens mounted on a plastic carriage that moves from the center of the disc toward the outside as it tracks the disc.  It will have a small ribbon wire harness that can expand and retract with the travel of the laser-eye carriage.  Now look at the two-parallel shiny metal bars the carriage should slide on. The lubricant on these bars lets the eye assembly move smoothly without vibration (or skips) over the length of the two steel bars and your CD plays perfectly when they are clean and lubricated.  This skipping problem can occur if something sticky is spilled into the unit. Soda or beer dries out and if it gets on these steel bars the laser-eye assembly can vibrate and chatter as it tries to track over the CD's info causing skips.      So the solution involves carefully testing the unit with the lid off to see what is going on inside when the unit plays (or attempts to play) a CD.  If the obstruction to the path of the eye assembly is severe, the tiny drive gears can be damaged, broken, or stripped and the eye will not move smoothly without new parts (Factory Authorized Service Personnel are recommended in that case)   Use the Denatured Alchohol and swabs to completely clean and dry the steel track rods that the laser - eye slide on, take care to clean any built up old grease (manufacturer lubricant) that may build up on the holes on the sides of the Laser-eye assembly where the steel track rods go through it.  After cleaning the rods use a new swab to apply a TINY amount of petrolatum evenly to each rod.  I cannot stress enough how important it is to use as little lubricant as possible ONLY on the rods and NOWHERE ELSE!  It is very easy to get the petrolatum somewhere you don't want it.  Be Careful!  One mistake here could cost you the entire unit!  after application, physically slide the eye assembly over the bars to smooth out the petrolatum lubricant evenly. (in the event the eye-assembly doesn't manually slide, don't force anything and go to the next step). make sure you did not get any petrolatum where you did not want it, if you did clean it with cotton and good old, denatured alcohol and put a CD in and before playing it, advance the tracks from track 1 to the highest numbered track and back several times to smooth the lube more.  Play the CD and replace the lid and screws in the order you removed them.      Good Luck!

I have Onkyo cd player DX7500 and when I play the cd skip constantly.


Try opening up the unit and cleaning the lens using a cotton swab and alcohol. The skipping is caused by the loss of the tracking information from the disc or the motor getting stuck. While the unit is open, clean the silver rail that the optics assembly rides on using a dry cotton swab. That should resolve the problem assuming that the optics are not starting to fail. These units can be adjusted a bit as well, but that requires an alignment CD as well as some test gear. Let us know how you make out.

Static and skipping


You might need to have it professionally cleaned / diagnosed. The problem might not be a dirty reader, but a misaligned tray. Many trays, over time, become misaligned. Some more than others. Depends on your use and abuse of the unit. The issues generally happen towards the end of the tracks.

Cd track skidding


This can be the first sign that the optics are starting to fail. It can also indicate dirty optics. Try opening up the unit and cleaning the lens using a cotton swab and alcohol. Also, with a dry cotton swab, clean off the "sled rails". These are the shiny rods that the optic assembly rides on. Sometimes the grease on these rails can collect dirt and cause the movement of the optics assembly to be erratic. Let us know how you make out.
