My Sony CDP CX455 turntable will not stop spinning. I think the laser lens may be dirty. If I open the case, where will I find the lens and what does it look like?

This site is located in CA USA so we have no access to local businesses in your area, so sorry. Check the phone book or contact Best Buy they repair this stuff I am told.

if you have the old belt, take it to ace hardware and get an o-ring the same size. it will work just as well.

Pretty much the only thing you can try at home is cleaning the laser lens, if the cleaner works then remember to use it now and again.
If the CD lens cleaner does not work the take it to the nearest sony tech/dealer for repair. Multi CD systems are very complicated and need specialist attention.

Hope this helps
Thanks for using FixYa

It is clear symptoms of bad optical laser or dirty optical lens.
Please put lens cleaning CD in player, play that CD to clean dust on optical lens surface. If that helps, fine or replace optical laser block in player.
I can provide you optical lens part number, please confirm is it Sony CDP-CX153 cd player or any other model.
Thanks.

Your laser lens is probably dirty, try a laser lens cleaner if that doesn't work, unplug the unit and take the outer casing off and manually clean the laser with some alcohol and a dry cotton cloth, would also be a good time( see that you have it apart already) to lubricate the moving components with some Vaseline.
Hope this helps with your problem.

Without turning the unit upside down, look at the bottom of the player. You should see a small round hole toward the front of the unit, with a white plastic part inside with a slot. Take a screwdriver and turn this gear manually with the power off. You should be able to unload the discs by rotating this gear. Be careful not to tilt the unit, as the discs will fall out of the tray, and you'll have to open it to retrieve them.

Once you have the discs out, put in only one disc and see if the unit plays. If you get a disc error, you probably need to clean the lens on the laser. Open the unit, use a cotton swab that has been pre-wetted with glass cleaner to wipe the lens on the laser. Do this gently, don't press down hard on the lens. Use the other end of the swab to dry the lens. Try loading a disc with the top cover off and see if it spins. If it doesn't spin, try turning it by hand. If you can't turn it by hand, the gears have gotten out of alignment.

In this case, use your screwdriver again, noting which way the gear on the bottom of the unit spins when the drawer is going into the unit. Then turn the gear until it "pops" past one or two teeth, and then you should see the laser assembly rise up and meet the clamp assembly on the top of the tray. These are the most common problems with the 5 disc players that Sony made. Many times I could fix them in 30 seconds or less using this procedure.

You have to open the cabinet ..with the power off!! with tray open look at the laser it should be in the cd home position..move the laser toward away from the spindle motor or turntable.you should see a switch with a cover over it,it may be black or white or clear..the is your laser home switch..with your finger or small screw driver gentely push the switch towards you or bend it towards you.with the cover off.plug the unit up.Watch the laser as it moves away from you towards the cd spindle, it it stops and the tray moves in, and the cd mech chucks .you should see the laser turn on and see the objective lens move up and down..if it does not..and it continues with your original problem the you have to retime the tray and loading gear..try this first..

did you have any luck with swapping the channels to determine if which is bad, cd or system?
