I've tried all those except taking the box apart which is what I was trying to avoid. There is no pin hole anywhere on my box! That's what everyone told me. Put a paper clip in the pin hole. Apparently every DVD player in the world has a pin hole except mine.
I guess I'll take the box apart and if it's the spring, I'll accept.
I do appreciate your taking the time to answer, but I've done all the things you said, except, as I said, taking the box apart.
