MP I have used one of those lens cleaning CD's that you speak of. I personally find that using a cotton or foam swab works better for lens cleaning. Compact discs have better sound quality that mp4's do because of audio compression. Thank you for commenting.

DVD player repair was interesting, and Mark, your lens adjustment lesson has made it even more interesting. Your player has only two motors because there is no CD tray to be motor-pushed out and pulled in. This eliminates th frequent problems caused by a worn out driving belt that links the CD tray to its operating mechanism. As someone clearly points out, most of the lens closely attached components, in whatever form, were considered a 'no go zone'. Some adjustment screws had a paint marking. Though lens cleaning could be done by playing a specially designed CD disc that had tiny bristles on it at a particular place for cleaning the lens. The CD played no more than two minutes as sweet music on it went on. DVD players remain dear in the hearts of many. I still cant help but marvel at this great technological masterpiece that is becoming a rarity too soon. Flash discs may have arrived so early to compete for space with DVDs in the digital data storage devices. Memory sticks flashed discs out. is what I see.

Parasuraman you do have to be carful not to over due it while adjusting the current. You can use a marker or something similar to mark where you started from. Or you can measure the pots with an ohm meter so you know what the values are of the pots. Then give the pot a quarter of a turn then try to see if it plays the disc. If it does not give it another quarter of a turn. In these compact disc players and CD players there is only one pot that controls the laser diode. I know DVD players have two pots one for reading DVDs and one for audio CDs. Here is a link to a video that might help. https://www.youtube.com/watch?v=DHpnVLR8TDs

It has worked for me many times. I have fixed many DVD players and CD players using this method. Thanks for commenting Albert.

Cleaning the lens only once did fix the not playing dvd discs at someone's house who smoked a lot of cigarettes.
The tip to increase the laser current by giving the potentiometer a small turn did not help to fix my Amiga CD32 game console. And neither did help to fix the same issue in dvd players where the red laser became a larger red dot. My brother had the same dvd player and both stopped working after only about 6 months. Replacing the laser head (Sony manufactured lasers if I am correct) by a new laser head in the CD-32 is easy and they are very cheap on Aliexpress. But they come with a special ESD protective solder jumper that needs to be removed first before using the laser head. And for about 15 euro these CD-32 consoles are as new again afterwards.

Vow! I have never ever tried adjusting the pots on the lens like this before! I was under the impression that the setting should never be disturbed. Many thanks for sharing this as it gives me strength to make an attempt. I just want to know which pot has to be adjusted. Normally there are two on it. Is one for voltage? Kindly guide me!
