Dvd will state no valid disk new or used. - Durabrand DUR7 Portable DVD Player

HI,

The problem is with the DVD player.Pleas use a leans cleaner to clean the lens.

I will give you more home remedies if they don't help then you will have to get this repaired.

no PC stated
no OS stated
no source of recovery disks stated (HP, MS or crack.org)
or home made?DVD-R or CD-R?

the answer is all you said and more.
lots more.
bad disks wrong disks
bad CD drive
bad HDD drive.
or if laptop then main battery is bad (bigone) and overloads it.

why not boot to live linux disk (optical media)
UBUNTU, 16, FREE, BOOT IT AND HIT TRY ME.
See if PC runs ok.
then if that works run DISKtest during the above demo try me.
if that passes we we are at
bad media install disk you have (no os stated or class of media)
bad cd/dvd drive.

DVD-RW
It is the re-recordable version of the DVD-R. To use this type of media you will need to buy a DVD-RW recorder. The DVD-RW recorders usually record DVD-R, CD-R and CD-RW media, too. Similarly to what happens to DVD-R, DVD-RW disks can be played in newer commercial DVD players without any problems. Older commercial devices cannot recognize the media, refusing to play the disk. To play a DVD-RW disk, commercial players need the disk to be finished. After finishing the disk, you can only record new data in it by reformatting it, which makes you lose all the recorded data.

DVD+RW

It is the re-recordable version of the DVD+R and everything that was said about the DVD+R is valid for the DVD+RW. Only the newest DVD players play movies recorded in disks using this format. There are recorders on the market that can record both DVD-RW disks and DVD+RW ones. These recorders are called DVD?±RW. Similarly to the DVD-RW, the disk needs to be finished to be played in commercial DVD players, and to record new data in the disk after having finished it requires reformatting it, which makes all the data in it to be erased. DVD+RW recorders are usually capable of reading DVD-RW disks (but not of recording them) and vice-versa.

There you are.

1. Bad optics or spidle motor go buy a new one

give no valid disk

try to clean the lens using cd cleaner or cotton buds with drop of water on it. that really works.

May be dust/dirt on the lens, so try blowing gently or using a DVD cleaner disk.

Same here!!! We've only used it maybe 8 or 9 times. And it's been worthless for the past month because of it. It reads everything "no valid disk" and nothing will work. And I tried e-mailing customer support several times, with no luck.

My unit will format single layer DVD but not double layer. Anybody have a solution ?
