I had the same problem as many other accord owners. My radio display went dark, I replaced the entire PCB (printed circuit board). Everything lights up like it should but now my radio code doesn't work. I looked at the packaging that came with the PCB and no radio code. I've tried my code six times and its on error 6. I'm afraid I'll lock it up if I get to 10 or something. Has this happened to anyone before? I'll have to call my job in the morning (work at the dealeorship). Just wanted to enjoy some music tonight if anyone has any answers..
