I didn’t have time to get through Ernie‘s post, but I would rearrange the order of the turn on sequence. Start with the TV on first, and have at least a five second delay before the Integra comes on. Make sure the other source boxes are on.
Then try with the Integra on first, and have the television come on last. I think I have seen this work before.
There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions.
