This is probably front end overload on a TV without a front end. Can you spell SDR? The TV may now be using this technology.

Even TV frontends that *do* use SDR use extensive filtering and a downconverter to go from the UHF input to a fairly "normal" 40MHz-ish IF.

A digital TV MUST receive all of the packets to display a useable picture. If it looses enough packets, it will not decode anything.

You probably cannot fix the problem with this TV.

I don't see why you couldn't. You just need to get rid of that grubby little splitter, and fit a highpass filter to keep the VHF signal out. I do this all the time.
