dvd player

[adams]

we have an auction on tv here that comes on just about every night and they have quite a few dvd players that hook up to your tv that won't read the disc.

now, can anyone tell me what would cause this and how easy it would be to fix? They usually go for less than $20 so if it would be something easy or not expensive to fix i would get one.

i put it here so that it will get more views and it doesn't really have to do with computer hardware.
thanks.
