Question about Sony STR-DE595 5-Channel Amplifier
Hello i have a sony stereo amplifier that originally had a problem in the electronics, went back for service three times (no sound at all), after that it worked fine.
after some years (the device is not used so often) it again shows some hick-ups, i.e. there is no sound. only after some time (when it is warm) and the volume knob is put to very loud, it all the sudden might start yelling through the speakers (waking you up for sure)...
does anyone know how to do troubleshooting to find the root cause (what to check, bad soldering? which component to replace, ... etc)
thanks in advance
My first suspect would be the output relays. These can get corroded over time and the classic symptom is that you get no sound at low volume levels and high volume levels will kick in the sound. There may be other issues as well such as poor solder connections. If you don't have any experience with this type of gear, have this checked by a service center. The cost should be minimal.
