This morning was going so well, coffee, breakfast, etc... Then upon starting up the car I noticed my radio would not turn on. Here's the scoop... 1990 420 SEL with factory AM/FM cassette, not modified. Yesterday I turned the radio on by pushing the cassette into the player. Everything worked fine. Starting up this morning, at 20 degrees F, car ran fine, however, radio would not turn on or off. The LCD has only the readouts for the base and treble on the left side and an FM readout on the right side. No station readouts. Also, when I put a cassette in the lights all work, the FF and REW works, but no sound. What can I do. I already checked fuse 18, its good, and removing it did not make the LCD readout change. Also, the antennae goes up and down as it normally would when the radio is on. Thanks for the help.
