These lens cleaning discs are nothing but smal brushes that may on occassion brush off any loose dust on the lens. If you can open up the unit, try cleaning the lens carefully using a cotton swab and alcohol. That MAY resolve the problem. If not, I think that the optics have failed and may need to be replaced.

Keep us posted.

Tray #1 won't read cd most of the time

Insert a lens cleanig disc into the device and play it at least three times. If the fault is due to any dirt or dust accumulated on lasser pickup lens, thei will rectify the problem. If this does not help you, the laser pickup lens unit of your device should be replaced with same type and number. The lens cleaning disc can be bought from most of the electronic sparepart shops at your town, and won't cost more. OK.

Selective playing of DVD's on Sharp DVD Recorder

Given that the machine will read disks it has written itself but not play regular discs, I suspect the lens assembly is slightly out of alignment and needs adjusting. This is not normally something you can do at home unless you have the correct test gear. It will need to go to a repair shop. One thing you can try before that is to clean the lens. Buy a quality (Scotch 3M, Philips ) cleaning disc and try it. Could be it's only a speck of dust on the lens.....

Row Jukebox 100B CD stops playing half way into a song. system error light is flashing on. I cleaned the lens, didn't help

It sounds like your laser lens may have or be in the process of kicking the bucket.
What you CAN do is adjust the POT on your lens...a fairly simple process if you can get at the lens assembly. Not so simple if you have to take everything apart to get to it.
Google "laser pot adjustment" and read up on how to do it.
If you aren't tech-savvy you may want to consider purchasing a new device or drive for your device.

CD does not play. I ran a cleaning disc, still does not play

Cleaning discs aren't 100% effective. It's possible the pickup lens is still dirty and not able to read the CD. The best way to clean the lens is by gently swabbing with a cleaning solution designed for cleaning them, but it's not always easy to get clear access to the lens.

The laser may just be too weak now to work reliably. Their power does drop with aging and use. The pickup is replaceable, but part cost and labor may make it just as economical to buy a new player. (I fix these things, and I just bought a new player myself. It was only $20 more than a new pickup would have cost for my old Sony. A seller on eBay had a great deal on new 5-disc Onkyos.)

Also, is this playing any CDs at all? Some older players don't work well, if at all, with burned discs. If you're having trouble playing home-made discs but commercial ones play, this may be why. (It's also a symptom of pickup failure, though, so that may still be the trouble.)

Cd's are skipping. cleaned discs and still skipping. tried cd's in different player and they work fine.

3M makes a CD lens cleaner that is a playable CD with micro brushes sticking out of the surface of the CD.
You can find them at office supply stores, K-mart, etc. I don't remember where I bought mine, but it works great for a CD-recorder that I use in a high dust environment.

Here's a link
to one that I just found by googling "3m cd lens cleaner"

I've never dealt with that vendor before, but it has a picture of the product so you can see what I'm talking about.

If this helps, please be sure to hit the "thumbs-up" for me!

I put a disk in the recording drive, and it says insert disk. Don't know what the problem is. Can you help me?

That happens very often when the laser reader is dirty or damaged. You could try a laser lens cleaner cd (available in any RadioShack) and if it fails, you need to take it to service for cleaning, although it's not really difficult to do it yourself, you can damage the lens permanently.

Lost link to my chat session

I am the person you had the chat session with. I have no idea why the chat ended. I can help you thru this posting if you wish to continue.

I had mentioned in the chat that you needed to take the top off the unit, and you said you did that but did not know what to do next.

You need to locate the CD mech, the part that picks up the disc and spins it, and then plays it. That part has a clamp on it, it should be in the back middle of the unit. It has a part inside of it that is called the laser pick up. That laser pick up has a lens on it. You need to clean that lens. The lens on it is small and round and looks like a piece of glass. Use a Q-tip and and put a small amount of windex or rubbing alcohol on the Q-tip, just enough to make it moist. Then just use that to clean the lens of the pick up by putting the Q-tip on the lens and moving in a circular motion until you see that the lens is clean. It should never take more than about 5 or 6 circular swipes on the small lens to clean it. Then after you have done that, wait just a couple of minutes and try to play a disc again. If the disc start to play you are done and cann put the top back on again. If it does not play, let me know what it does and I may be able to help you further. But in most cases, if cleaning the lens doesn't help, then you need it serviced by a technician. There are no other secret fixes that make them work besides cleaning the lens, that the user can do. Any further service it may need will require some electronic troubleshooting skills and the proper tools to do that.

Won't play discs. Instead conitnuously rotates showing 20 segments per disc, no matter what.

Yanaha has had lots of bad laser pickups the past several years. It has to focus before it will spin. Sometimes they will focus and spin but still not read the disc. mybe you can try to clean the lens... CD lens cleaning discs: Every CD, stereo equipment, department, discount, store - and even sidewalk venders - carries CD lens cleaning discs. Are they of any value? Can they cause damage? I generally don't consider CD lens cleaning discs to be of much value for preventive maintenance since they may just move the crud around. However, for pure non-greasy dust (no tobacco smoke and no cooking grease), they may not hurt and could even do a good enough job to put off a proper cleaning for a while longer. However, it's also possible they will ruin the lens. Consider that the worst thing to do to a precision optical surface is to wipe it with a dry cloth as this is likely to scratch the surface as it rubs the dust over it. To the lens, a speck of dust is like a boulder. Once the lens is scratched, replacement of the entire optical pickup is the only remedy. And, since there are absolutely no sorts of standards for these things, it is possible for a really poorly designed cleaning disc to damage the lens even if the dust itself is non-abrasive. In addition, if the cleaning disc doesn't look like a CD to the optical pickup or disc-in sensor, the lens it may not even spin. So, the drawer closes, the drawer opens, and NOTHING has been accomplished! (But at least no damage will be done.) As if this isn't enough, NEVER put one into a high-X CDROM (DVD player or DVDROM drive). The high speed rotation may cause the cleaning disc and/or player/drive to self destruct. And, don't try a cleaning disc on an automotive CD player that sucks in the disk - it will get stuck.
