Playing music What's happened to my GPX player (model CDPW8805). My batteries are new, but it doesn't play. No disk reading, nothing. Can someone find a solution?

When the lid is closed on your player there is a little switch that is activated (closed) letting the player know you have inserted a disk and you're ready to jam out. Sometimes they are fairly easy to find and sometimes they are located in places that aren't so easy, like in the hinge. For the most part, there will be a hook- like piece extending from the lid of the unit which, when closed will activate the switch on the other half of your player. If you can find this hole where the hook goes into, check to see if it is making contact by taking a tooth pick or something similar ( nothing metal !! ) and activating the switch manually with a cd inserted.
