Hello i have three portable dvd players and after a while they all done the same thing they all say no disk when disk is inserted. I have try'd different disk but keeps coming up no disk can you help please advise
you can try manually cleaning the laser lens ( gently wipe , do not press down hard , it is suspended by fine wires ) using a q-tip and a drop of that cleaning solution you got with the laser lens disc. ( fluff another q-tip a little ) then dry wipe it with another q-tip and try a disc.
you can look at the laser lens and see if you see the laser come on also to determine if that is working ( do not look directly into the laser ! )
if the laser works but it still does not read discs after cleaning it manually , then there is a problem with the focus coil on the laser or the signal board is bad
I work for Coby technical support. Our customer service phone number is 1-800-727-3592.
the unit is showing "invalid disk" on every disk that you try to play,
unfortunately, the unit has developed a defect and needs to be
replaced. Our warranty is 90 days from the date of purchase. If you've
had the player longer than 90 days, I regret to inform you it is out of
If you feel this solution doesn't deserve a good
rating, please let me know why so that I may better assist you. If
there is anything more I can do to help, I will!
It can be several reasons
1. Disk is upside down
2. Lens is durty. CD/DVD cleaning disk will help
3. Disk is in different formate (for instance NTSC for US but you trying to playback disk in PAL)
4. Disk has different region code (look is the dvd player and disk have the same code, or ALL Regions code)
