Chosen Solution
Yamaha 6.1 avr Amplifier: I have to choose denon because there are not option Receiver makes a noise to all the speakers channels like static, very loud them by itself shut off, when receiver turn on for a brief time shows “check speakers wires " then even without sound going like movie or music STILL makes the static noise”. Any help will be appreciated, Thank you in advance
Hi @flamini , Try disconnecting one speaker at a time (do this with the power Off) and then see if the noise disappears when the receiver is turned on again Update (01/25/2018) Hi @flamini , I think that you may have accidentally blown the power transistors in the amp, possibly when you connected it up again. If you had the unit powered on when you were connecting the speakers again after you moved it, then perhaps a speaker lead may have s/c (short circuited) the output and blew the transistors before the protection relay could operate. You’ll have to open the unit (definitely with the power removed) and see if you can spot any damaged components. Here is a link to the service manual for your receiver. It details how to dis-assemble the unit, has schematic drawings and board layouts as well as part numbers if you find the faulty parts and need to order replacements. If you find this too daunting contact a reputable, professional electronics repair service, preferably audio repairs, and ask for a quote to repair the receiver. Good luck
