I have a Philips dual deck CD recorder CDR775. The problems occurs in the playback side. When I load a cd, be it pre-recorded or a finalized CDR-RW it does not play the disc. I would like to go through the progression. First of all the door opens and closes intermittenly, and sometimes not at all. When the door doesn't open, I would have to turn the power off and back on again in order to open the door. After inserting a disc, it goes into the reading mode, and then it starts to scan and that's all it does. Sometimes it will flash Not Finalized. When I remove the disc from the tray it will continue to read and scan. I NEED HELP!!!
