    G-9000DB Distorted sound on left channel (Solved)

    I have this receiver for 6 years now and had no issues with it. Last week the left channel started sounding distorted, even on headphones only, which means this is happening prior to the amplifier side of the house. It starts getting distorted after 10-20 seconds. I did notice that without...
