Problems- Factory Radio Swap

I just replaced the factory tape deck in my 97 tahoe with a factory cd player. It worked fine for about a half hour but now I get no sound from either the cd player or the radio. It doesn't show any error message and it's not locked.

I reinstalled the tape deck and it works fine. Why would the cd player quit?

Did you check the connectors on the back before you put the tape deck back in? May have wiggled loose.

Yes, I checked all the connections.
