HI,

see if the player tries to read the disc. Load a disc and listen.
Does the player make squealing noises or is it totally quiet? Squealing noises may indicate that the player is trying to synchronize with the disc but can't due to an obstruction on the lens or in the laser path inside the pickup or a defect in the pickup. This can also be caused by an intermittent signal problem due to a faulty ribbon cable.

Totally silent means that the photo sensor is not getting any usable input from the laser at all, meaning that the pickup is "blind" for lack of a better word.
This can be caused by an obstruction of the beam by foreign matter on the lens or inside the pickup all the way to a marginal or failed laser diode and/or photosensor array. This can also be caused by a bad ribbon cable with one or more severed traces.

You could try to clean the optics. This is the most common malfunction as far as i know in all disc players. It would involve taking the cover off and finding a way to expose the lense, and then cleaning it with a very gentle brush. some players have a cover for the lense that swings to the side during playing, this greatly reduces the chance of dust accumulating, but its still worth the try.

If you actually see dust on the lense, then its just that simple. clean, close, play.


It may also be worth your while to check on the small shafting that guides the carriage of the laser pickup. Dirt, grome, dust and solidified lubricant can cause stoppage of the carriage and the laser eye then fails to read the next track. Please refer to the image i have attached.

Its time to replace the optical unit ( lens ) of the CD player. Brace yourself the unit on some of those old players can cost more than a new DVD player.

I have a kenwood MIDI M-45 /MIDI M-757 audio system. The CD player won't play. The disc loads but error comes up NO DISC, can you help????


The cd unit is not reading the disc, the laser pickup may be dirty, or the pladder motor that cd sits on may be defective. If you can get at the laser pickup lens, clean it with rubbing alcohol with a Q-Tip very carefully in circular motion and allow several minutes to dry.

Rcd159a boom box PLL digital radio- plays all the old mp3 cd's with a write speed 16x & under but any newly burnt one with the high speed disks fail


That's not unusual. Slower burning speed results in a deeper burn which is easier for some players to read. Unlike commercial discs which are highly reflective, burned CDs don't bounce as much light back to the laser in the pickup. Too fast a writing speed when burning can make some discs unreadable. This is why some older players can't read burned CDs at all; they were never sensitive enough to begin with. It's always a good idea to keep the write speed low (16x or so) when making CDs that will be played back in a regular CD player or boom box.

This problem is more likely to occur as the CD pickup ages and the laser weakens. If higher-speed burned discs used to play and now are having problems, it's probably time to replace the boombox (or the pickup assembly if you're ambitious). If the higher-speed discs never played, the player just can't deal with them and you'll need to keep the write speed down when burning CDs.

I have an Aiwa stereo cd player that only plays certain cd's but not the new ones, it is model cs-na222


Some Aiwa players will not play burned, non-closed or expanded limit cds (CD of 700MB or overburned to 750MB).

When you say new cds do you mean purchased pressed cds or ones you created?

This is a typical problem when the laser " eye" gets dust on it, unplug the unit and you can try to remove cover and spray the optical pickup "eye' with canned compressed air or other type of optical cleaner found at say like radio shacks, I have solved many disc reading errors with this method

Hellow Sir: I bought Aiwa XR-MS3, now the piece has a problem. It can recognisze some CDs, and some CD it can't recognize. thank you very much Yong


First you need to clean the disc's that it will not play. If a disc has a fingerprint or scratch on it in the area of the disc that is at the inner-most part of the disc where data is at, most CD players will not play the disc at all. Some will, but most will not. That area is the part of the disc that is called the TOC, it stands for "table of contents" and if that part can not be read, the disc can not be played. It has all the information there about everything that is on the disc. If the player can't read it, then the player has no way to find anything on the disc.

Try using windex and a soft cloth, like a bath towel or something soft that won't scratch the disc. This method works better than anything else you can buy for cleaning disc's and it is much cheaper.

If cleaning the disc's doesn't help you should try cleaning the laser pick-up lens. many retail outlets like Best Buy sell a disc that you can put in the unit and run it for about 20 to 30 seconds and it will clean the lens. It doesn't work great, but it will clean it a little. If you are able to see the laser pick-up and get to it with a Q-tip, you could try cleaning it with the Q-tip. Put a very small amount of windex or even isoprophl alcohol on the Q-tip and then very lightly rub it on the laser lens. Don't use a lot, just enough to get the Q-tip moist, and that will clean the lens better than anything else. It is the way professional technicians clean them. I have been repairing audio equipment for over 18 years and have lots of experience with these type of units.

If cleaning the lens doesn't help, you have a weak laser pick-up that would need to be replaced. If it is under warranty, take it in to an authorized Aiwa service center along with your receipt and they will fix it for free. This unit should have a 1 year warranty and as long as you have a proof of purchase they will fix it. You do not need to have registered your purchase when you bought it, many people think that it is required, but it is not. All you need is the receipt, which if you no longer have can sometimes be given to you by the retail outlet you bought it from. Many retail outlets have that information stored in the computer systems. Or you could check your credit card statements, if you used a credit card, and that is often accepted as proof of purchase. I have even seen some people who have contacted the manufacturer thru the customer service number and get a letter from them authorizing a one-time repair under warranty. You know that old saying, "The squeeky wheel get the grease". Sometimes it helps to call and complain, or just explain that you lost your receipt. If the unit is one that has been in stores being sold within the last year, many times they will allow for a free repair.

I hope this helps you with your problem, and if so a rating of "FixYa!" would be appropiate and very much appreciated, after all, it is the only reward we get for offering people like yourself free support for your problems.

Thanks, and let me know if I can be of any further help.

It is the laser, If the cd mech is in the top of this one you may just need to clean the lens manually. Cleaning discs are not all that reliable. You can do this by taking the top off and looking at the area where the disc gets clamped to play. The laser has the small glass lens. That is the part you need to clean. Take a Q-tip and wet it very lightly with some windex or some alcohol. Make it so that the Q-tip is just barely wet. Then just lightly rub the lens without pushing on it hard at all. Just nice and easy over the glass lens. Then dyr it off with the dry end just like you did with the wet end. That's it. close it back up again and turn it on and see if it plays. If it still does not play you need a new laser. No other fix for it.

Same problem here...I determined that if you unplug the receiver for a few hours, it will work again for a week or so.  Someone else on this website said that it had something to do with the power relay switch:
