Disc inserted but NO DISK message appears

Try other discs to see if its still working properly...most likely the recording on the disc is not burnt properly or there's something wrong with the disc, (ie, scratched or surface dirt etc) or the DVD player just can't read the disc...for example can it read the type of disc(does it read dvd+r or dvd-r, or both?--- if i remember rightly)..... I've had discs that have had bad recordings but can still be read if placed into tray a particular way around... randomly try different positions, also cleaning disc as you go...depending on how desperately you want it to read the disc...could also be bad disc batch... there could be many reasons...

My dvd player says no disc, with a disc in it , what does that mean?

Means it cant read the disk.
Either disk is faulty or your heads need cleaning or you have inserted a type of disk it cannot read ie a rewritable one.

Keeps saying wrong disk


The reason it is showing wrong disc is because the laser/lensisnot reading the disc.

The reason the laser/lens is not reading the disc is because it is either weak or dirty.

To fix it if it is dirty, try to clean it with a lens cleaner.

If it does not work, then it means the lens is weak, and to fix the lens you have to replace it with a new compatible lens.

Get the appropriate screwdriver, open up the cover, unscrew the disc tray and try to locate the lens and replace it with the new one.

test with a DVD disc.

Take care

My daughters GoVideo DVD player always says CHECK DISC!

If no disk is detected it means that the lens are dirty or defective.
If the lens cleaner disk, or using Qtips and alcohol did not work, then the lens pickup or the disk drive must be replaced. this involves precision soldering and must be done by a technician. Regards.

Player shows '' No Disc'' even when inserted with a disk

When player says no disk, even if the disk inside, and you hear a whirring and clicking noise when you insert a disk, that means that the CD lens is dirty or defective, and the CD drive cannot read the initial CD track, and returns no disk.

Try first using a CD cleaner disk, if that does not work, then you will need to take the apart the unit to clean lens with isopropyil alcohol and cotton sticks.

See also the following websites on how to clean the lens, use a cleaner disk first:

Hope it was the non-acetone type of polish remover - acetone will melt plastic !!

Invest in a laser eye cleaning disk - the kind with the tiny brushes.

OK what type of file format are the files in on the disk you are tying to play?

IDM-1731 does not like .AVIs.

Check your documentation as to what type of files your player can actually read and play.

Sorry I'm not more help.

Coby TF-DVD7100 7" portable flat screen...keep getting "Wrong Disc" Error

I have seen this problem on several Yamada & Xoro brand DVD players. If you remove the lid after powering down with the disc tray closed and a disc in it you may well find the ribbon cable to the read head is rubbing on the disc. The ribbon cable is held to the base of the box by a sticky pad under a 45 degree bend in it and a piece of sticky tape !!!. Power up unit, open disk tray, power it down, retape cable to base securely with small strips of duct or gaffer tape (using tweezers helps) and hey presto it will work again. The cable rubbing slows the disk spin speed hence "data read error" unit assumes "bad/faulty/wrong type of disk". All that technology screwed up by using a cheap bit of tape in the factory assembly, amazing eh !.
