A power level of 100% with the other parameters at zero suggests that the tuner is receiving "garbage". It might be noise ingress, but I'd suggest that it's either amplifier/tuner overload (IMD) or it might be a defective amp that's oscillating.

A CM7777 is way too much amplifier for your TVFool plot and is inappropriate for your signal levels. Remove it completely and retest the system "barefoot".
