The DVD laser pickup is at the end of life, replacement of assembly the only option, cheaper to replace the combo unit.

Try to see if the drawers are blocked by something either inside or outside of the case.

Did this problem just start? It may be due to the lens no longer reading the disc. Try a lens cleaner. If your lens went south, it usually is paired with a clicking noise or/and the combination of a no disc/disc error message. I would also recommend staying away from Polaroid dvd players and tv's in the future. They have a habit of not making parts available, especially after the warranty.

It sounds like U have a bad lens. Try a lens cleaner. If it is the lens, it wont read anymore discs. Sometimes it will also make a clicking sound and show disc error/no disc cryptic messages on the screen.

try cleaning the unit with a disc cleaner.and make sure all dvds are clean

I turn it on and all i get is a blue screen. It will loading disc and say bad disc.

yeah stay away from polaroid! In the meantime check this out.
