Audio Systems: 2000PontiacMontana audio system not working, pontiac montana, radio problems

Question
I am looking for any help with my audio system on my 2000 Pontiac Montana van. The whole system shut down. It does not light up at all. no clock, no radio, no CD, no cassette. My husband checked the fuses, they were changed , it worked for l day and then it went again. We tried fuses again and to no avail, it's not working. Any suggestions ?

Answer
there is 3 fuses for the radio    there is no reason for the radio to urn off just liek that  that radio problems are bad cd, bad display  or rear speaker problems but it it still takes the cd and tape or play on the fron speakers the display is off and  the light around the radio on
