I have a 1994 Maxima with a radio/cassette made my Clarion for the Maximas. Mine was installed in 1996 to replace the original when it went bad.
Six months or so ago, the radio display, green LED type, stopped working, completely. In other words, the display was pure black, whether the radio was turned on or off.
This condition lasted a couple days, then the display returned. That lasted for a couple months, then it went bad for a few more days and returned. Then two months ago while the car was in the shop having electrical work done, a fuse blew and the radio didn't work at all until that fuse was replaced. The display didn't work then, and hasn't worked since. Until tonight, and now it's back as good as ever.
During this time, I have done nothing to try to fix or identify the problem. It's just come and gone on its own. When it first started, it was summer here, with temperatures typically 85 Fahrenheit or hotter and 35 or 40% humidity. Now it's winter, and tonight it's below zero F. The car is in a garage when it's not being driven.
What could be wrong with my radio display?
