My Threshold Fet10HL works perfectly with the exception of the Audio/Video input. I have tried known good sources and other inputs to make sure the problem did not exist in the source. It is definitely the preamp Audio/Video input that is causing the issue. I get no sound from any source using the Audio/Video input on the preamp. Any idea what conponent/components could contribute to this problem only existing with that particular input?
Yes, both L and R channels. No finger poking yet. Only opened once to clean volume potentiometer. Did not have a need for this I put before so never knew it had a problem. All other inputs work without issue.
