There's a chance the Laser that reads the disk has gone bad. Most lower end players are not worth repairing, as it would exceed the cost of buying a new one

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,
VOTIT

Press case lid where it attaches to player. If this makes unit react you have a defective lid switch. You can probably put some weight over it to hold lid down and it will operate. Otherwise switch must be repaired

SOURCE: my phillips 5.1 dvd player not playing dvd disc, only playing vcd

the laser lens on the optical pickup is dirty or scratched. to clean: buy a disk cleaner and use it per instructions. if it doesn't help, you can do it manually. remove the top, remove the top off of the disk assembly (you may have to remove the whole assembly first) until you see the lens. be careful with the cables and wires. use a lint-free swab (not a q-tip and not your finger), gently wipe off the lens. replace the covers and test. if it still doesn't work, it may be scratched or damaged. in which case, it needs to be replaced.

My CD player keeps displaying no disk and wont play the cleaner disc, is something dirty or broken?


Hello
If it does not play the cleaner disc, just inspect whether the disc inserted in spins inside it. You can check this by open the upper cover of the player, and inserting a disc into it. If inserted disc spins inside, and the player won't read it, the fault is with its laser pickup unit, and it should be replaced with same type and number.
If the disc dos not spins, the fault is with the sled motor [the motor that spins the inserted disc], has damaged, and should be replaced. OK.

I have a Sony Psyc CD Walkman D-Ej010 and I will have a cd in there at it will play for a few minutes and then stop and say no-disc. What could be the problem?


There may be a couple of reasons why a NO DISC , DISC ERROR or INSERT DISC error may appear in the display of your CD player. Try doing the following steps to troubleshoot why the error is displayed:
  • For disc players with a HOLD switch, make sure to move the switch to the OFF position.
  • Verify that the disc being used is supported by the CD player. NOTE: CD players do not support VCD or DVD discs. In addition, some CD players do not support CD-R or CD-RW discs that are created by a CD burner. For information regarding disc compatibility with your player, refer to the operating instructions supplied with the product
  • Ensure a disc has been inserted into the player. Make sure that the disc is inserted correctly, with the playback side of the disc facing down on the disc tray.
  • If the disc still does not play, attempt to play a different, commercially-produced disc.
  • NOTE: If more than one of the commercially-produced discs do not play, verify whether the discs are extended-length discs. Some players are not able to play discs where the recording exceeds the standard 74 minutes. If the recording of the disc is longer than 74 minutes, it is possible that some of the specifications of that disc were compromised and therefore, the CD player will not recognize that disc.
  • If the disc is dirty with fingerprints or smudges, or if the disc is scratched or broken, the CD player may not recognize the disc.Clean the disc using a soft, dry cloth.
  • Properly reinsert the disc into the player.
  • Attempt to play the disc again.
  • Only press the PLAY button once. If the PLAY button is pressed more than once, the disc may stop playing.
  • If the disc is still not recognized, remove the disc and leave the CD player powered on for approximately one hour to resolve the possibility of moisture condensation inside the player.
  • Please use a Lens Cleaning disc and check if that helps.

If the issue persists, please click hear to locate the repair facility near your area.

Thanks for understanding. Please let me know if you require any clarifications.
