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 touching anything, the distortion will go away after 1-2 minutes for about 10-15 seconds and then comes back again. I cleaned all pots and switches with DeOxit D100. I also cleaned and played with the CONNECTED/SEPARATED switch on the side, but again, since this is happening while also listening to headphones only, I did not expect it to fix the problem.
I decided to go for recapping, hoping I have a bad capacitor. I changed all the caps on the F-2799 Tone & Flat amps board as well as the F-2796 EQ Amp board, all capacitors met specs but I replaced them all anyway using Nichicon Audio Gold where possible. That did not solve the problem.
Looking for ideas where to go from here, I plan to replace all capacitors and relays on F-2809 Power supply but not sure it will help as well.
Thank you,
