My LG LM-M1040 mini hifi system will no longer read discs. It has been sitting in the same place since purchase 2yrs ago and has only been used a few times. can you help


Hello,

The problem should be from the lens (laser).

The lens is weak and that's why it cannot read/load Cd's.

Get a lens cleaner and use it to clean the lens, but if the lens still does the same thing even after using the lens cleaner, then it means you would have to change the whole lens completely to a brand new one.

By so doing your player would play all Cd's with no problem at all.

Good luck.

Aiwa cxzr525 cd player. After loading under the eye cd does not spin or play. It just clicks. I tried a cd cleaner disk and that did not work. Is it the same as a lens cleaner? What else can I try? Thank...


The clicking you are hearing is an attempt to focus on the disc. The usual cleaning discs don't work well. Try to gain access to the lens and clean itusing a cotton swab and alcohol. That will remove any film that remains on the lens. If that fails to resolve the problem, the optics will need to be replaced.

Good morning, I need your help for my Aiwa NSX-SZ50 digital audio system .... It went in demo mode, what can I do to start again ???? It is possible to have another manual ??? Many thanks for your...


you can order new owners manuals online in many places. Search for Aiwa NSX-SZ50 owners manual.

I would try unplugging it, and then play a cd... it should snap out of it. if not, look through any menus you can access.

Will not read the disc


The optical lens assembly is damaged at this point. the lens has burned out and the tracking/load motor seems to be faulty as well. replace the optical lens asap.

I have an aiwa nsx 5200 mini system the cd player broke


Soooooooo many people have complained about this system not reading discs properly, yet the solution is incredibly simple. All you need to do is calibrate the lens, and you can do this without even opening the stereo! Here's how:

With the stereo all unplugged, turn it around so the back is facing you.

Now use a flashlight and, looking through the grating on the back, approximate where you think the cd lens mechanism would be. You should see 2 8-pin connector wires side by side (one red and one white) and to their right a small black circle screw type thing.

Using a screw driver, turn the screw thing about 1/10 of a revolution clockwise.

Plug in, and test with a clean cd. If nothing happened, repeat the procedure turning the screw thing in tiny increments (don't over do it.) Eventually, the cd player should recognise the cd. Keep fine tuning and testing until you've found the "sweet spot" where it recognizes and plays cds optimally.

Overall, you should NOT have to turn any more than a full revolution, and even half a revolution is pushing it. What you are really doing by turning this screw is fine tuning the "data reading point" of the laser. Too close and it will focus on the area between the cd and the lens, causing failure to recognize the disc. Too far and it will focus past the data perhaps recognizing the disc but not being able to read it. I believe the major problem with these players is that as they settle in, the area between the lens and cd changes. This would cause a gradual degrading in performance until the player finally failed to recognise any data at all (which is exactly how mine went personally.) There isnt a problem with the quality of the lens itself, therefore it is very fixable!

I have heard that all 3cd Aiwa Mini-systems share this problem so, as long as the calibration tuning screw is exposed through the grating on the back, this fix should work for any of the Aiwa mini-systems with this particular problem. If the screw isnt exposed, it is still possible to get at by opening and dismantling the player. (Unfortunately, i did not originally notice that the screw was accesible through the grating, so i went about pulling the entire system apart and wasting hours of my life. You can thank me later for saving you this tedious trouble as you're listening to cds on your newly fixed player ;-) )

If this doesn't work, or doesn't fix the problem completely, try cleaning the lens. You can do this by either by using a cd lens cleaner (looks like a cd with a brush built into it) or opening up the stereo and using a soft cloth on the lens. You may also want to try putting the screw back to its starting point and using the same procedure but turning the screw counter-clockwise. (I personally had to turn clockwise but who knows, maybe your player settled in differently.)

As for the mechanism itself, i have no idea. I did notice, however, that the lifting mechanism sometimes picks the cd up off-centered causing failure to play. You can semi-fix this by holding the stereo at an angle while it picks up the cd or placing it off-centered in the tray. Its annoying, but it works :)

YAMAHA CD PLAYER WON'T PLAY


GG  My kids had a PlayStation 2 that did this and so did my AIWA 3 CD player.  The solution for the PlayStation was to remove the cover use alcohol and clean the lens of the laser reader.  They get dust on them and simply cannot read.  The AIWA required replacement of the laser which cost almost as much as the unit and didn't last 6 months.
