gee, if it's on (lights up) then you have power so it's not the fuse. Ever think that maybe the radio just decided to crap out? That's my idea. heck I have a pile of factory stereos that crapped out which I've been fixing and selling on ebay over the years.
So, the display does not show any radio stations, but will show the time. No audio no matte what i do. All the buttons are lit up like they should be. It will accept and eject a cd, but will not play it.
