My Sony stereo model number HDC-C33 has stopped working. The word "Initializing" scrolls continuously across the display window. The Radio and tape player work fine, but the CD aspect of the stereo is completely locked up. It will neither eject or play the cd that is currently loaded. How do I repair this problem. One day it worked and the next day it didn't. The unit is older made in 1994 so I don't want to spend a fortune to have it repaired.
