I bought a portable dvd player for my nephew bday coming up. I thought id try and see if the dads I had to go with it would work with it. I shit you not I tried 6 dads then all of a sudden its telling me there is no disc in it when there actually is a disc in there. I've tried to dust the lens and whatever else. I think it's cooked. im disappointed. how can I fix this?
