Bought an 87 IROC a few months back and the radio worked perfect, factory unit.

Now fast forward a few months, and when i start the car, the screen is blank. When i push the power ****, the clock comes on, no music plays and after a few seconds, the screen goes dark again.

Want to keep this car stock, any ideas of how to get it functioning again?

Thanks
Tony

 

That's how the radio functions when it has no accessory power, just b+. Check the rdo fuse first, then make sure the power is going to the radio with key on.

 

Time to have all the capacitors replaced. Had same scenario as U & that is how mine was repaired.

Voltage from the RADIO fuse is on the YELLOW wire on the BLACK plug. If you have a good fuse,.... might want to probe that YELLOW wire at the radio.
