DVD recorder started showing red LED as if in recording mode. Not able to stop it. Not even able to play DVD as DVD door won't respond/open. Checked its HDD on computer and has two healthy partitions, one with 300 MB is Fat32 formatted and rest unformatted. There is some stuff on 300 MB which I could not open and nothing on the other partition. Could anyone suggest what is wrong with it and I can fix it?
