DVD player troubleshooting help

I have a KEC Mobile Applications DVD-2, a basic dvd player. When I insert a dvd, and more specifically when the optic mechanism begins trying to read the disc, the power from the unit fades away. The lcd display turns completely black, and 12 - 15 seconds later, the unit ejects the disc and all power is restored.

I have tried several different dvd's. Can anyone help? Thanks in advance!

I removed the unit and opened it's case. I reconnected the power supply to find the disc-spinning mechanism was getting stuck. I blew into the assembly repeatedly until a piece of paper or plastic loosened and flew out. The unit is now functional again.
