I replaced the fuse today and it didn't help. I just want to reiterate that I have power to the amp, I'm just not getting anything out. When I plug in the head unit the light does not go on (not a blown LED, I checked). I also took apart the head unit competely and found it to be in what appeared to be perfect condition. There is no head unit fuse like some were suggesting on the site.
What I've done:
Replaced R12 and R26
Checked Diode next to R12, was fine
Rewired arround burned spots on PCB board, no result
Checked head unit - appears to be fine
I'm running out of ideas and I really don't want to spend $50 to have someone else fix it. I do have access to an oscilloscope through school...is that where I should go next?
