Pioneer DEH-PB40MP No Power

hey, indeed this sounds like a couple of fuses gone bad. I dont know this accurate model, but it shouldnt work any diffrent.
Anyway, with the stereo UNPLUGGED remove the covers and inspect inside, especially in the vicinity of the power transformer. The fuses may be glass cylinders with metal caps. There are other types, but the only ones you should probably try to mess with are the glass type, usually about 5/8" long by 1/8" wide. They should ONLY be replaced with the same type. Somewhere on the cap will
read something like 3A, 4A, etc. This is the ampere rating. Replace only with same rating. It is foolish and dangerous to just go out and grab whatever fuse is laying in your car's glove-box, for example.
There may be a couple fuses. As I said, there are other types of fusible devices, but they would require a tester and some limited knowledge of electronics to test. The glass-bodied fuses can usually be seen to be either good or bad by looking at the filament inside.

have u checked the trucks electric fuses in the fusebox ?check for ACCESSORIES fuses.
then go for any further experimentation.
as for the RESET BUTTON,use it after your stereo comes to life .
i do hope this solution helps
