Question about Coby DVD-218 DVD Player
Whenever a DVD disk MP3 cd is inserted, that's the message I get: Loading ..., then 'no disk. Tried cleaning, but this did not help. Tried unplugging and wait overnight then try again, this didn't work. Tried adjusting the variable resistors on the lens assembly, nothing! My other suspicion is the motor that spins the disk itself, it seems to be going a bit slower. Maybe there is circuit component(s) that broke down or the motor may be bad. If there is a solution or confirmation, please let me know.

SOURCE: wrong disk problem
Then lens may need a damp isopropyl alcohol qtip run over it a few times, use 90%. If that doesnt work then try a cd cleaning disk to put in the player. The cd or dvd may also be too scratched to read.

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.
If 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 warranty.
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!
