Question about Pioneer DEX-P9 CD Player
When i play a cd for a while the unit must be getting warm and begins skipping on track.
Any ideas what the problem is? i heard its a common and fixable fault?
read somewhere it could be the disc clamping assembly?
Looking for a fix
Try going to the Pioneer website and find the DEH-p3900mp page. Click on the documents tab and click on owner's manual.

SOURCE: cD skipping with the bass
Has it always done this, or is this a new problem? If this is a new problem you may need the unit serviced. It may need the lens cleaned, or laser replaced. If the laser is getting weaker it can do that. They also have these small oil filled dampers used like shock absorbers. If one of those is torn and has leaked a little oil out it will skip much easier. They also use springs to support the cd mech, if a spring has streched out or come loose, that can also make it skip on big bass hits.
You can always try putting some foam or something around the radio to help keep those heavy bass hits from vibrating the radio. But then the radio may get too hot.
Make sure the radio is very secure in the dash.
If this problem has been going on since you installed the radio, you have an installation problem. The radio is a little loose and prone to move around a little.

SOURCE: cdj 800 keeps skipping
Does it keep skipping, or does it keep looping? 2 very different things. If it's skipping, it will sound like it's scratched, and will only skip on some CDs, and not others - unless your tray is messed up.

Sounds like the laser lens is dirty or out of focus. You can take it apart and try cleaning the lens with a soft cloth and see it that works. If the focus is out of adjustment, that takes alot of patience and time. Never look directly at the laser with the case open. On the bottom or side of the laser lens, there are two small box looking gadgets about 1/4" square with tiny screw type adjusters in the center of them. These are potentiometers, they can develop dirty or burned spots over a period of time. Turning them slightly can give you better performance. If I remember right, one of the pots is for width and the other for height of the laser focus. You can identify them by the small ribbon cables that run to them. Try a very small turn on one and try playing the dvd. Mark with a marker a straight line across the pot and board to know where you started, believe me it helps. This can take quite a while and may or may not work. I find this to be the biggest fault with most dvd and cd players. I have fixed many this way. By the way, I use a jewelers screwdriver. They have small plastic ones for these, but they are hard to come by. Good luck.
