My Beam freaks out and squeals/feedbacks when I turn my TV off. It doesn’t happen every time, but frequently enough to be super annoying. My TV is a TCL with built in Roku. Any thoughts?

If I were to guess, it's an issue with the TV sending a bad signal to the Beam....but I could be wrong. The information in the diagnostic should indicate whether it's a signal coming in, or a failure in the Beam.
The other thing I'd do is make sure that the TCL has the latest firmware update on it.
