Re: Harman Kardon AVR 370

Hello, today I have speakers and it turns out that one channel in the amplifier, the one that was damaged, plays quietly and creaks, it is SURR.LEFT

Re: Harman Kardon AVR 370

You likely have more damage in the driver circuit. Take measurements and compare against SURR.RIGHT channel.

Hello, I checked all parts and they look good and the sound still creaks

Hello, I was able to fix it but I don't know what I did, that the central speaker doesn't work, the receiver does not sound central
