Has anyone solved this or have a service manual please? I'm guessing preamp but the cost of sending it for repair is too much, and local repair costs are very high!
@HotBiker ; I haven't found the solution yet , due to other business now. A fact is that the preamp board will be hot at some places, I wonder if this could be a broken line on the printplate. 2nd option I have to look at is a faulty electrolytic condensator?
I bought a PA for my next gig, but I hope I can fix the HK Audio.
After switching on, the system goes into mute several times, but after a while it remains stable at on (temperature?).
