Put cd's in and it can't seem to find them. Searches and doesn't play anything. Have had the laser focus lens cleaned, focused & aligned, and the carriage assembly cleaned and checked. Problem persists.

Hello Patricia,
is the cd player dirty? many years of dust can tarnish the player laser lens and the disc reading will be hard or impossible, for to do it you need to open the player, then remove the disc upper holder if present and clean the lens with a cotton swabs or a simply cloth with alcool. then let it dry for some minutes. Blow before with compressed air will be a good thing if the dust is plentiful.
if you can get to the laser eye take a paper towel or tissue paper soak in rubbing achole and clean the eye if you cant reach it or it is hidden in the mechinism get a disc cleaner and run that in the system it sounds like the laser eye is dirty i do it to my cd player all the time when it can't read the disc
it sounds like the tracking coil on the laser opu has been damaged during cleaning,,,the lens is suported on two axis . the focus coil moves the len in and out .this is ok because it plays for a bit. then the tracking coil moves the lens to track the disc in sync with the sled movement of the assembley .this is were it is going wrong .. you could look closly at the tracking coil support etc and see if anything obvious .but if not will require new laser op...
Ok, it sound to me that the laser lens which actually reads the cd's has some dirt particles on it.
There is a very cheap method of solving this problem. Just go to any cd shop and buy yourself a decent laser lens cleaner disc, follow the instructions and you should be set.
This is a problem with the laser assembly which requires service. The laser assembly needs to be replaced as a whole. It is not easy to replace them, but someone with patience, and a knack for mechanical things can do it.
I contacted a friend who operates a sterio shop and was convinced that fifteen years of bouncing up and down has made the laser unable to focus and read the info on the disks and the solution is to buy another one . Thanks for you're interest.
If thhis happens quite often , and does not depend on the media, then it is usually a dirty lens problem. The lens is dirty or scratched and sometimes cannot read CD TOC (table of content).
If this happens only on reocrded CDs , try changing the media used. For example if you used +R, try with -R.
If this happens on all media, then try cleaning the lens with a lens cleaner CD or blowing some canned air on the lens.
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.
Does it show the disc length or any other details? Have you carefully cleaned the lense with a q-tip and some alcohol? Can you hear the laser moving in and out of focus? If you push the laser sled out away from the centre does it move back to the middle when youi put a disc in?
If you trust yourself enough to open the case w/o breaking stuff, then open it up UNPLUGGED, locate the laser lens (small,clear,plastic) gently clean the lens with a swab of lens cleaner for glasses. Also clean the chrome runners that the laser assembly tracks on.
