Gerry,

1) Remove ALL the cables (except the power cable) and see if you have the problem.  
If you do, proceed to step 2. At this point, there should be no antenna, no cable 
TV, no audio outputs, no video inputs or outputs. 

2) Study my RFI tutorial and use it as a guide to wind a toroidal choke on the 
power cord tuned to 20M.  If that doesn't help, take the TV back for a refund. 
It's a shielding problem, and you'll never fix it. 

3) If the choke on the power cable fixes it with no other cables attached (or if 
there's no interference with only the power cord), start adding other cables one 
at a time that you need to make the set functional the way you want it. If the 
problem returns, that cable is acting as a receive antenna, so add a choke to it.
