Ive today bought a pioneer avh-p7500 from a con man on ebay which had all the bus wires cut luckily i had a old unit that got water into it a couple of years ago the model was a 6500 but the cables were the same so i fit these in and goto the shoop and buy a power lead 45 quid.
getting excited i plug into the car without the face on and the little light on the front flashes.
so i pops the face on and nothing not a flicker a noise nothing so i presume the switch live has gone.
i know a little about car audio and i know there is a transister that basically acts like a light switch on the 6500 there is 1 on the 7500 there are 2 im just wondering if this is where i should be looking.
my only fear is that when " the ebayers cousin took it out of his car " ******** he has burnt the entire unit cutting through the bus leads.but i cant smell any burnt out internalls
PLEASE HELPPPPPP
I dont know too much about these, but what i do know is, most of these units have a small 1 amp continuous blow glass fuse inside the unit, i would have a look to see if yours has it, and also look for any signs of over-heating on the PCB
