What about analog Audio. If your RF signal gets weak you can still have
analog audio and AC-3 RF but you will start loosing the digital decoding
which would be both the stereo outputs and the digital outputs.
It is now scary that you said the previous owner was adjusting things.
Hopefully the tech working on it will look at the RF level test point and
check the amplitude, that is the first step.
