Radio/CD-No sound

Hello! I purchased an 02' Chev Impala with a stereo/CD (factory) that does not have any sound. When the radio is playing, it displays which radio station is playing, tells us what song is supposed to be playing, but NOTHING comes out of any of the speakers. The same is true for the CD, shows what track and CD is playing, but nothing has ever come out of the speakers. Not even static or any noise at all. Could this be LOCKED UP? Or what do others think might be wrong? Thanks for the help!! Tom :rolleyes:

has this radio ever played music since you have had it ?

Is the mute button on ?

No it has never played music for us, the mute button is not on, Thanks

Amplifier fuse blown (if so equipped)?

since you are getting no sound anywhere you really have 2 choices - either all 4 of the speakers are blown (happens more than you think) or the amp on your headunit is trashed (could be a blown internal fuse).
