hey all, i got a bluetooth audio receiver thats no longer working, it was used in the car it allows the phone to connect to the receiver then it outputs audio to the alpine head unit using the alpine AI-Net connector which is probably just an aux input of sorts like rca.
iv opened up the casing to see if something obvious is wrong but cant work out what could cause it to not power on. 12v power does get to the board input points and iv probed the T4 smd diode near the power cables and its showing fine readings, OL in one direction and 0.6 drop in other.
anyone on here good with electronics know where i should be looking?
