Remove the battery off for some time and keep aside. Use a clean ear bud to carrefully clean the lens eye of the laser head.
Insert a good original DVD and test. If there is no sence to rotate or move then it is possible that the head had failed.
Is it possible that a damaged CD was put into? or a wild cleaning done?
You might have to change the optical head assembly....... or a possible mother board is not ruled out.

Hi, i see this many times a month similar units to this what happens unfortunately, is the laser head and or quadrant detector simply go faulty, or perhaps get dirty scratched etc. You could try a head cleaner, but i do not think that will make any difference, but is worth a try. Unfortunately again this isn't really economically repairable even if one could get parts, which seem unobtainable.
Contacting Coby direct also may work for parts, and a service manual tooif you wish to DIY.

You may be able to get it repaired though if you can find an agency that deals with them all the time, they may have units that are faulty in other ways and they could use the laser system out of a junked one... I sometimes do this if i can for my customers.

All my DVDs say "invalid" when I try and play. This just started all of a sudden. Was working just fine before.


Always first unplug for a minute and make sure the discs are VERY CLEAN. Sometimes my player/recorders give an error message 2-3 times but eventually are able to load the disc.

Player reading invalid disc and disc is not spinning


My dual screen dvd player was reading invalid disc and disc was not spinning. Took player completely apart and white gears had dirt in them. This was preventing the player from spinning. Used dust remover and cleaned the whole inside and now it works great.

Coby DVD shows Invalid Disc HELP PLEASE


Did you make the disk if you made the disk your computer has to give it a digital signature so the DVD player can read it if you're using a regular DVD then I would very carefully using rubbing alcohol and Q tip clean the actual laser I would be very careful doing this if too much rubbing alcohol is on the Q tip it will ruin the laser you can also try resetting the DVD player by taking out the battery and unplugging it from any power source and leave it that way for at least 20 seconds to a minute if that doesn't work you might have something else wrong

Deck A will not play/Deck B OK


Sounds like the CDR deck has an issue. When the disc comes out has it's position changed i.e has it been spun at all? Can you hear any motors moving? Does it work with any type of disc ( cd/cdr/cdrw)?
