The Quad processor is an evertech, Model EV-CQ204
Yes I agree, I back tracked to figure what I might have done to cause the issue; no luck. The thing just stopped working. I bought a new quad, thinking this may be the issue (It was not too expensive) to no avail.
I moved the receiver, like I said, to another monitor, and it worked fine. Foe some reason, the receiver stopped receiving, in the current location.
This is not the quad issue, I don't think, because I moved another input to the channel the problem receiver is on, and the new input works fine.
I them moved the Problem receiver to Quad channel two, three, and four, and it doesn't work on either
This is an analog quad, and all sources I have into it are analog
This one is a challenge!
