I have a 1995 Honda accord and I was driving one day when my radio just went blank. Then it says code on it. So I entered the code and right as I enter the last number the radio makes a beep then the radio goes blank and I can't do anything. No sound nothing on the screen and none of the buttons do anything. I have tried a few times to pull the fuse and put it back in and the same thing keeps happening. Any thoughts?
