I have a Ministry of Sound Stereo in my Mitsubishi. It has worked perfectly for months but has now developed a problem. The radio is fine but if the stereo has been switched on for about half an hour the CD player does not work correctly. It pauses and the display goes blank for a few seconds. It then carries on playing from where it paused for while before doing it again. Any Idea what the problem could be?
