Last night I popped in a new DVD into my DVD (Panasonic A120) and got a message 'NO PLAY' on the DVD display and a message 'this disc cannot be played' on my TV. This morning my 3yr old son pressed the open/close button on the DVD remote and when I pushed the button again and sent the DVD back into the player, the DVD started playing. I did this again but this time it wouldn't play again. I did this a few times and after a few tries it started playing again. I tried other DVDs but this happens only on this particular DVD. My question is why does this happen on any DVD. If the player can't recognize the format (or something) that should happen everytime. Why does it happen sporadically? Could it be that my DVD player is dying? Is there some way of resetting a DVD player in case there is a problem? So far the A120 has served me really well without any A/V dropouts or any of the other glitches. Its been running for the past three years without a single problem. Is it nearing the end of its life?
