Sony CX355 skipping Fix

I have a Sony 300 disc changer that started randomly skipping tracks after it was 8 or 9 years old.
I tried cleaning it, no change.
I opened it up and found an adjustment screw on the reading lens carriage.
Note: It is very hard to see
It rotates approx 1 turn from stop to stop. It was centered from the factory.
I rotated it counterclockwise 1/2 turn, and it got worse.
I rotated it clockwise 1/2 turn, and it is fixed. It hasn't skipped a beat since.

Cd skips at beginning of cds

the data on compact disks usually starts on the outside of the disks and spirals to the center. My guess is that the laser unit that reads the data is malfunctioning. It moves on a rail from the outside of the disk to the center. About all you can do if try to clean the laser unit or lens assembly. If you can get to the laser lens, blow it off with canned air. If you can not get directly inside, open the CD drawer and shoot the canned air into the machine through the drawer openings. I suggest that you open the CD drawer with the open button then unplug the machine. At that point the drawer should be open and you will have some access to blow off the CD reader.
good luck cleaning the CD reader!

After insert disc-won't play-reads no disc


Does it apply to all disk's if so change the lens it might be worn out
Your problem is in all cd players not only Sony .
Try cleaning the lens with lens cleaner or a cotton wool touching the lens gently slightly it might have dirt and interfering with sensing,reading.
2, check if the lens is being moved to its position center begining so it can start to read by the motor .

good luck

CD player does not rotate

Hi there.

There could be a couple of reasons. I doubt very much that it is due to the lens. First thought is that it is probably the locking mechanism. If you look at the cd loading mechanism, there is a small plate with a locking tab that moves into place to hold the carousel still when the unit is loading a cd. This plate slides along the bottom of the unit between the cd loader and the carousel.

Secondly, it could be that the carousel is jammed on the rotating platter that it moves on. A couple of screws and it should come out - be carefull not to bend anything!

Thirdly, check the stepper motor that turns it - but I doubt this is the problem either as you said you couldn't turn it by hand either. You will need to remove the carousel to do this.

Good Luck !

Occasionally doesn't cue up

I have had this problem as well and found out a couple of things in the process. The offending deck sometimes just does not find the proper cue marks on the disc. I have unplugged the interconnect cable and plugged it back it, this resets the unit and this appears to work for a few times.

However, I also opened the bottom unit and cleaned the laster lenses, we are in a dusty climate and the dust builds up no mater what you do to control it.

If you choose to clean the lenses, you will notice there is a gear near the openings of the laser. Turn off your unit and rotate the gear so the laser shows in the opening. Clean the lens, I used a little Windex and a cue tip. Rotate the gear so the lens is in the position it was before you moved it for cleaning.

These units do not have an "adjustment" per se. This can be caused by a bad sensor or a dirty sensor. The tray have slots in the bottom that are sensed to determine position. A loose belt, bad sensor or noisy power supply that causes noise on the sensor line all can cause this. DO NOT dis-assemble the tray assemble as the loading timing of these is not the most intuitive and is difficult to return to the correct position without a complete rebuild. This should not be an expensive repair. The sensor for this will be around $5. Add in the local labor rate for the complete repair cost.

I have done 100s of these over the years. Have the lens cleaned while the unit is open as well.

CD player skips on early tracks

The lens assembly in a CD player glides along on a two rail track, kinda like a railroad track except tubular. The lens carriage is moved over this track by a small motor driving a worm gear. (Think long, tubular and spiral). If the rail tracks or the worm gear dry up or have dust accumulating on them, this could be the cause. Normally they have a light gear oil or lithium grease on them to keep them lubricated.

CD Player problem

Most DVD players that would not play a disc even with a known good disc inside signifies that the llaser eye/lens is not reading the disc. This could probably be attributed to:
1. dirty, damaged, inverted, blank, un-finalized burned CDs or DVDs;
2. defective, weak, dirty/dusty burned-out laser eye/lens;
3. dirty, dried up lubrication of the slider shafting (where the laser eye's carriage moves) or some other components; and/or
4. dirty, dried up lubrication, defective spindle motor.

A few things you can try:
1. Use a CD cleaner (readily available from most computer shops);
2. use a can of compressed air and blow through the inside of the loaded disc area;
3. gently tap on the top cover where you estimate the reading/laser eye/lens would be;
4. gently press on the tray door once the disc is loaded;
5. relube, clean as necessary

Should this not be corrective, perhaps your best bet would be to seek the services of a qualified professional such as those in a Service Center. Alternately, your friendly neighborhood electronic shop should do just fine.

Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kindest regards.
