Hello Everyone!
After so many days!.. Finally back to begin with some interesting stuff I always love to work with.
If anybody can please assist me in correcting a problem with my Yamaha HTR-2064, which has its surround speakers stuck on mute.
Everything is working fine except the above. Troubleshooting so far has not yielded any result. So far comparing the voltages, show there is a 3.3v at the base of the transistors Q205 and Q206, which should be approx. minus 12. Other transistors base, of the muting circuit, shows -12v.
I have attached the service manual for reference, so if anyone has come across such a problem, it will be great if they can assist me further on this.
Thank you and have a nice day.
