Hello

The laser could have simply become bad. But usually it is just one or the other (meaning CD or DVD). I would suggest checking the cables going into the drive and make sure they are properly seated and haven't come loose somehow.

Try cleaning it this helps most of the times, use any of the cleaning disc available in a local computer shop if that does not work then try reinstalling and everything else fails take take it to your vendor

Manually cleaning the lens
To locate the laser lens, look around the door or drawer of the DVD player and you will see a small circular disc, which is often called the turntable or disc platter. Right off the edge of the platter you should see a small clear lens. There are some manufacturers that have had problems with the lens, depending on the age of the unit. In these problem players, moving the unit to a different location, turning the unit upside down, or sometimes even without moving the unit, the lens can become detached from the laser assembly and floats around inside the unit. You can re-glue it back with a little crazy glue, BUT it must be perfectly centered, and without getting any glue on it. So, if you don’t see the plastic lens, but instead see the laser pick-up assembly, look around for the lens inside the unit and glue it back on.
To clean the lens you must use very little pressure. Take a cotton swab and barely moisten it with plain, non-scented, or oily type alcohol. In a swirling motion, very gently rub the lens until you’ve covered it entirely. Then repeat using the dry end.
If the cleaning didn’t help, don’t despair just yet. You can see if there’s a problem elsewhere in the unit by using a few simple tricks and tips.
First thing you want to see if the unit’s laser is in good working order. This method isn’t foolproof, but most of the time works admirably. When you insert a disc, see if you can look up underneath where the disc sits on the turntable. Observe the laser lens going up and down. If the lens is trying to focus, that’s good! After a few seconds of the lens trying to focus, the platter should start to spin. On almost every CD/DVD unit I've encountered, the unit won't spin unless the laser has properly focused on the surface of the disc. If the unit spins up and and then shuts down, you should check and make sure the laser pick-up assembly slider mechanism is working without any obstructions and that the small chrome rail that it slides on is slightly greased. Don’t go overboard with the grease though, as too much can cause all sorts of problems.
The slider mechanism, depending on the age of the unit and the manufacturer, consists of the small chrome rail, a drive motor, a small gear assembly, and (in some units) a small belt that drives the slider unit via the motor. This small belt causes all sorts of problems. If the belt is broken or slipping, it can cause skipping, dropouts, or simply no start up at all. Also, if the belt breaks in the middle of the disc, the drive mechanism gets hair or dirt wrapped up into the gears, or the pick-up assembly doesn’t return to the start position (called home), the unit will (99% of the time) refuse to release the disc, causing it to become stuck inside the unit. There’s a little micro or leaf type switch located at home position that sometimes gets dirty or breaks and, causing this problem also.
If the disc starts to spin slowly and doesn’t come up to speed, the spindle motor that’s attached to the turntable platter is a common problem. There could also be a problem with the spindle motor driver controller IC or the power supply regulator that supplies voltage to the driver IC. If the disc starts to spin and then spins really fast, or stops and starts to spin backwards, your problem is the laser pick-up assembly or the servo control circuit. If you continue to have problems after cleaning and checking the other things listed above, you may have a problem with the player's alignment. Of course, one of the problems you'll face checking alignments on a DVD/CD player is that you’re going to need to use an oscilloscope on most of them. If you have the proper tools and equipment, the first thing to look at is the RF pattern of the unit while its playing. It should be a sharp and clear pattern. If it's dull and smeared, then the laser could be weak.
Also, in these units are very critical alignments called the focus/tracking gains and offsets. When these alignments are off, it can often cause intermittent troubles. As the unit ages and parts change value, so do these alignments, and will need to be checked. In my time as service technician repairing DVD/CD players, 65% of the laser pick-up assembles I have tested were good and only needed a small adjustment. Today's technology makes it unfeasible for a shop to hook up a DVD/CD player, and even some recorders, to their equipment and make these adjustments because of the cost involved.

Hope this may help;

Regards,

SOURCE: dvd player keeps saying No Disc, Insert disc

When it loads the cd does it say loading before it sais no disc? if so, it may be the laser assembly, you can try cleaning it with a cotton bud dampened with alcohol like ethanol, if that doesnt work it is likely the laser assembly needs replacing, if it loads and unloads or sais no disc instantly, look at the sensor inside the drawer, (needs to be dismantled) this could be a microswitch. I would personally look at the laser and clean the lens and while you are in there, clean the wormwheel and guide that the assembly glides on, there could be dust on that or the grease may have dried and the laser cant reach the TOC, regrease them lightly, look for any belts and just replace them..Hope that helps Phil

DVD player will play store bought dvd's but will say unknown disc when I insert one from Netflix.


Is it possible that this is a Blu-Ray disc from Netflix? If so, It may not be able to be read on a standard DVD player.
Another possible reason for this is that the disc is somehow damaged and thus unreadable.
I'm afraid without seeing the disc I am unable to help you further.
Either way, might be time to complain to Netflix:

My 2 1/2 year old LG dvd/vcr recorder will play some dvds but will not play others. It says unknown disc. I was told to try a lens cleaner; I bought one and the lens cleaner says unknown disc as well. ...


Hi,

Your DVD /VCR says unknown disc because the
dvd which you have inserted is not of the supported format by player.

If you insert unsupported formats only it will say as unknown disc.This is not related with disc cleaners.

Please insert the supported formats and it will play the disc.

Thanx

When i put a disc in, the screen says NG Disc, and the tv says disc cannot play... What can I do?


Hi,

You get it as disc cannot play this is because the disc which you have inserted is in format which your DVD player doesnt supports.

So please change the format and play in your DVD player.

Thanx

"No" message appears on player front.


Try inserting a cd, almost all dvd players can play cds as well, if it displays the same message you may very well have a defective dvd player, if it plays then you may have a damaged disc. If it plays the cd try a mint condition dvd; also, I'll assume that you know better but in many cases if the dvd player is not defective users are simply loading dvds in upside down. If all this fails return your dvd player to the store or check the warrenty.

I hope this helps, good luck

DVD player error


Try cleaning the lens using a cotton swab and alcohol. Next try playing a CD. If the D plays but a DVD does not, the optics are weak and need to be replaced.
Keep us posted.

No Disc


Stumpy, I think the first step could be to find out between the DVD player and the disc which one has a problem.If the DVD Player is able to play other discs then it is possible the problem is with the disc only. If that disc can be played quite alright in other DVD players then the problem is with your DVD Player. I suggest you trial that first. I think the indication of " No disc insert disc" could be that your DVD Player is failing to load or read the disc either because the disc has some scratches or because your DVD Player lens are not powerful enough. I am, Letsthank.
