Dvds are formatted in different formats.
Your player may not recognize the format on that dvd disk.
If it does it with too many disks then the optical eye on the dvd plyer may have gone bad or it isn't reseating in the start position correctly.
Hope this helps

    see if the player tries to read the disc. Load a disc and listen.
    Does
    the player make squealing noises or is it totally quiet? Squealing
    noises may indicate that the player is trying to synchronize with the
    disc but can't due to an obstruction on the lens or in the laser path
    inside the pickup or a defect in the pickup. This can also be caused by
    an intermittent signal problem due to a faulty ribbon cable.

    Totally
    silent means that the photo sensor is not getting any usable input from
    the laser at all, meaning that the pickup is "blind" for lack of a
    better word.
    This can be caused by an obstruction of the beam by
    foreign matter on the lens or inside the pickup all the way to a
    marginal or failed laser diode and/or photosensor array. This can also
    be caused by a bad ribbon cable with one or more severed traces.

    You
    could try to clean the optics. This is the most common malfunction as
    far as i know in all disc players. It would involve taking the cover
    off and finding a way to expose the lense, and then cleaning it with a
    very gentle brush. some players have a cover for the lense that swings
    to the side during playing, this greatly reduces the chance of dust
    accumulating, but its still worth the try.

    If you actually see dust on the lense, then its just that simple. clean, close, play.


    It may also be worth your while to check on the small shafting that
    guides the carriage of the laser pickup. Dirt, grome, dust and
    solidified lubricant can cause stoppage of the carriage and the laser
    eye then fails to read the next track. Please refer to the image i have attached.

My toshiba bdx2000 won't play the expendables.


Because of the lack of internal memory on this player and the mass of content on this and some other newer disks, you have to ensure that you have an SD card inserted with at least 2GB capability.

I have a Toshiba sd 3750 DVD player, I insert a disk, it spins up then it gives me a M-7 Code? I looked all over and can't find out what this code means?


Is the code only displayed for a particular disc, or any disc that you try to play? If it is a specific disc there is probably an error on the disc. If the code comes up with any disc you try you will have to take the player to a warranty shop to have them identify the code.

Your toshiba is not spinning that's why it keeps on saying loading. Unplug the dvd Open the device,once open plugin the dvd and put the dvd cleaner in the player. take your finger on the top where the dvd disk is and spin the disk. What happening is that you are cleaning the len. keep spinning until it spin on its own.Put the toshiba top back on and clean again. It should clean on it's on. Now you can play your dvd. Clean your dvd on a regular basic.

After approx 1/2 hour of play the movie gets stuck for few seconds, plays again for 2-10 seconds, then permanently gets stuck. Sometimes a smack to the machine works, ff does not work....we usually just...


Smacking the machine is a good way to destroy the DVD lens. Get a CD/DVD lens cleaner and make sure there aren't any marks on the disk. Dirt & smudges cause about 75% of all CD/DVD player problems.

Cd's are ok but no dvd's...


Had similar problem. Found the disk was not rotating. Adjusted the torque on the hold down screws of the drive unit allowed the disk to spin. Still had some motor noise, but DVD would load.

If the disk is not dirty, smudged up or scratched -- it is likely the laser pickup getting weak or the spindle motor not keeping at the right speed. If you have to clean the disc, wipe from the center out with a clean soft cloth.
