I disassembled the unit, and checked solderings..
There were some cracks on solderings of those power
IC´s (or whatever, sorry for my english.) Anyways, I resoldered them.
I´m now testing it.. We´ll see if the problem is solved.

check for dry joints around the power output IC and on main board. Thats the

eliminate that before hunting for faulty components.

Hi!

I have this AV-amplifier.. And there´s a problem.
After 30-45min on use, the outputs mute. No sound.
Works ok after turning off & on again. For a while. Then again, no
sound.
Amplifier works ok after it has heated up enough..

This seems to be temperature-related problem.. Maybe a bad soldering?
Or possibly some bad component? Any suggestions? I haven´t yet opened
the machine.
