My Becker radio stopped working and displays the error code E2. I have been told it might be due to a old electrolytic capacitor failing in the system. However, does the E2 code provide any specific information about what part of the radio has the fault, ie. the amp in the boot, the CD changer or the tuner in the car. Doe anyone have a list of the fault codes and their description? I have attached a picture of the radio. I understand my radio design was used up to 1992 although my car sold in Australian has manufacturing day June 1993.

Thanks for the info. Working on that now. I have traced down a repair manual for the radio/tape drive in the car but not the amplifier in the boot. Still trying to find that. I has a Becker model number but only the dash radio data is popping up.
