NO DISK READS 'NO DISK' FOR DVD PLAYING. I HAVE TRIED MULTIPLE DVD'S. WILL NOT READ EVEN THE LASER CLEANING DISK.

Hi, if your sure it stops in the same time on any disc then i would assume there is something stopping the laser from moving forward.
If your confident opening it things may be obvious, KEEP HANDS AWAY FROM THE MAINS COMING IN.
The laser runs on two metal bars but all the gears are plastic up to the motor. The motor does'nt spin but turns in small movements as the laser reads in front, sometimes the teeth on the gears get clogged up. Let me know how you get on.

its the disk laser sensor is to sensetive that why it canot reads with an ordinary disk or a pirated disk or a disk that has a small scratch.

That is a faulty lens. The lens reads DVD and CD on different laser beam frequencies. To read the TOC initial track the lens must focus on the laser beam reflected by the disk. If the lens is opaque, scratched or dirty, sometimes it can focus on DVD but not on CDs or the opposite.
Try using a cleaner disk, if that does not work buy a replacement drive. Today you can get a dual layer DVD RW for less than $30.

Get a laser cleaning disk and let it run in the dvd player for a few minutes then try playing a dvd. Its probably playing bad because the laser is dirty

Try cleaning the lens, also the inside of the player in and around the disk tray is probably full of dirt, dust etc, carefully try cleanig all that out, you may need to disassemble a bit to get at everything

Some dvd have a multiple laser function for dvd and use a single laser for cd. common fault on not reading dvd is dirt on laser or fault on multiple laser that cannot read dvd. If cleaning doesnt help only repair tech can fix. Just check that the dvd is working in another dvd player to ensure it is not disk

Is this a cheaper-budget brand player? If so it could simple be a dead laser. The old cheap apex player were prone to that. They only cheap solution is to try a dvd laser cleaner. Possible accumulated dust etc is on the eye. Other than that it is probably best to pick up a new player. It's a throw away world these days.

Unfortunately that means the laser is weak or dead. It deads repair.

The DVD-RAM Disk had trouble afeter Multiple recordings or any scratches. Buy a new DVD-RAM Disk and Try using that.

My Smasung DVD/VCR Combo stopped reading DVDs because of a dirty read head. It started by only playing disks sometimes, and progressed to never playing disks. I assumed it was a dirty laser lens so I bought a lens cleaner set. Unfortunately my player wouldn't play the cleaner disk.

So I took it apart and cleaned the laser lens manually with some isopropyl alcohol (the clenser that came with my cleaning disk), and a lens cloth (that came with my glasses). Just open the case (starting with the screws in the back) and remove the snap in cross panel that obscures the lens of the DVD portion. Put a drop of cleanser on the lens and gently wipe it with the cloth.

Oh and by the way, I take no responsibility if you break your own player while following my instructions. My own DVD player was far out of warranty at the time I cracked it open.
