Hey guys, I own a Denon AVR-3803 surround receiver for 15 years and it has served me well. Two days ago, as many times before, I turned it on and, when plugging a RCA -> 3.5mm Jack cable to my computer to listen to some music, there was a loud crackle and the receiver fried. I'm pretty sure I even saw a tiny sparkle between my Macbook (aluminum chassis) and the 3.5mm jack. The right channel works but the volume is really low and the left channel only reproduces pops and crackles. Speakers and headphones -> same result; Digital (toslink) inputs work perfectly fine; All analog inputs are toast. I know this is a pretty old receiver, but it was more than enough for my needs and I use(d) it regularly. Given its age, I know its value isn't much hence why I'd prefer trying to fix it myself instead of spending its value on a fix. Maybe it's only a fuse or something and it would be easy and inexpensive to solve, but I have no clue about where to start. Could anyone provide some guidance? Given the symptoms/cause, what do you think happened? What should I look for? Thanks a lot!
