So my cd player's really old and i was gonna buy a new one, but if there's a quick fix i figured why not. Everytime I put a cd in my cd players it either says ERR 3 or ERR 4 and wont give me back the cd until it feels like it. I did the obvious of cleaning the lense. Any other suggestions or should I just call it quits?

 

what kind of CD player is it?

try doing a simple search on google " ERR 4 on ( insert name and model here) cd player" see what comes up
