It sounds like the TV is very sensitive to power fluctuations. I use a UPS in all my setups as they seem to stabilize power and it also lets me have time to shut down in a PF. I hate waiting for the raid 5 to rebuild (on one of my systems) due to an improper shut down.
All of the previous suggestions should be taken to heart. Overloading a single circuit (depending on the house and when built) could kill you or someone you love.
Good luck.
