Need Radio Help Please-No Sound From Speakers

[slick]

Own an '03 Box, standard factory radio, has always worked fine. Driving home from work yesterday, made one stop and when I restarted the car there was no sound from the speakers. Other than no sound the radio appears to be working correctly. I pulled the fuse when I got home, it was OK, and after restarting the car, the radio took about 1 minute to reprogram but began working and speakers worked. My favorite stations were still programmed but treble, etc, needed to be reset. Went to bed. Started car up again this moring and once again, no sound from speakers. The mute is not on. Any ideas? Thanks.
