2002 chrysler sebring stereo

I have a 2002 chrysler sebring convertible and i am having some problems with my radio. there was a small surge i beleive when i was installing another small electrical device and when i checked my radio it looks dead. there is apr .5-.6v going through the power wire in the adapter (i beleive it to be the pink wire) and when the car is in acc or running position it reads 5+v. i have checked the fuses as well (just in case) and do not notice any of them to be blown. any help would be available to try and revive my radio
