Hi everyone.
So I picked up another dead receiver (just needed to be reset). This one is an older model, a RX-V475. Got it all connected and updated the firmware and set up all the basics.
I have 2 issues with the receiver, if anyone has some input it would be much appreciated.
Issue 1
When I use HDMI as the input source for audio it is distorted, but when I use the AV analog as input (Same source) the sound is perfect and there is no distortion whatsoever (I have tried multiple sources as well). So my thinking (correct me if I am wrong), is that the digital input signal is not correctly getting processed to analog by one of the chips on the HDMI board (The DIR / DAC or ADC)
Any advice?
Issue 2
All of the channels of the receiver are working correctly except the Front left channel. The front left channel sound quality (when using AV) is good and there is no distortion of any kind, the issue I have is that the actual output volume is very low(not amplified). Yes, I have done all the necessary test to eliminate speakers, wire, source etc. and have come to the conclusion that it is definitely the amp channel. Could it just be the power transistors that have failed (1 of the pair or both?). The amp also does not enter protection mode.
Any advice on this issue?
Perhaps Issue 2 is the cause of Issue 1? or vice versa.
Thanks in advance.
