I just purchased used a 1997 Volvo 960. The radio is a Premium sound system SC-815 that has both tape and CD capability. The radio will not work.

When pushing the power switch on, the screen is blank but the aerial goes up. When pushing the power switch off, the screen reads "OFF".

The person that sold me the car said the system was working fine, but they had disconnected the battery for some unknown reason and the antitheft device did not permit turning the radio back on. They had gotten the reset code from the Volvo dealer and had unsuccessfully reset the code even after several attempts.

I turned the radio for the two hour period noted in the owners manual and the word "COdE" never showed up on the screen nor the "EEEE: error screen. The Volvo dealer told me I had internal problems in the radio and that I would have to replace the radio, which sounds more like and "remove and replace" approach rather than fixing the problem.

Anyone who has some good ideas how to get this problem resolved would be most appreciated.
