Hi there!
I've got an amplifier AU-G90X and there is sth wrong with the left channel. Everything was OK until some days ago. When I turned it on the left channel didn't work. I thought it was sth wrong with the speaker but I checked both of them on both channels, on both speakers systems A and B and it was obvious that there was sth wrong with the left channel in the amplifier. I checked the electrical current adjustment back on the aplifier and it was set to 220V, and IMPEDANCE to (recomended if used A or B) 4-16ohm. I screwed the pannels off, vacumcleaned carefully inside. There was NO SIGN of anything burned or disconected.
When I give a little bit more volume, and turn the balance knob to the left ther is only "rippin and scratchinn", so it is not completely numb, but there is sth wrong.
IF SOMEBODY CAN GIVE ME SOME HINT TO WHAT MIGHT BE WRONG... ! THANK'S
