now im no noob when it comes to repair of electronics and what not I do that daily at work. But I have no idea where to start looking inside of my JBL GTO 75.4, I took it apart the other day and noticed no burnt smell or burn marks anywhere. The caps on the rca plugs do come off but they did that before it stopped working, sound I try replacing the rca inputs/outputs to see if that fixes the problem. I would really like to not spend the money to get it repaired to sell it for a minimal profit, id like to try and fix it. Anyone have any idea where I can start looking to see why it goes into protect right away?
