2001 Saturn Radio died after had battey jumped started

I hope someone can give me some tips? My car battery died, I got a friend to jump start my car and now the radio does not work.
I checked and replaced the fuse, still nothing. All other lights/panel indicators, etc work except the radio. There is no display, no time, etc.
Any suggestions? I have had the car jump started once before, no problem with the radio.
Thank you.
