Sure. Lousy shielding is a common problem and possible culprit. In 
other words, it could be picked up on the wiring within the TV. That 
means replacing the TV. 

However: It still might be coming in on the wiring that you choked. 
A ferrite choke is basically a very low Q resonant circuit, and will 
cover a frequency ratio of about 6:1.  Toroids aren't very useful on 
6M, because the stray C causes the choke to resonate much lower in 
frequency. In other words, what you have may be a good HF choke, but 
not a good 6M choke. Try adding a bunch of big #43 clamp-ons on the 
feedline and power line.
