OK so I'm sure I have a blown pico fuse thats common with Pioneer headunits. Grounding the RCAs took out alot of the noise but not all. I want to take it to a repair shop here in Japan but I want to make sure I can point out the correct fuse since communication is an issue. I see PGD which I think may be the pico ground and it looks like I have two pico fuses P1821 and P1823 is completely blank. If someone can tell me if I'm looking at the right fuse I'd appreciate it.
