• looks more like external noise on the signal - does it do this on dvd as well?
  • Seems to me to be a ground loop problem. If you have cable, make sure the cable company properly grounds your cable where it comes into the house and/or try ferrite rings, available from radio shack.
  • Hi, To me it looks like a set issue (does it do it on any input you use, cable,dvd? Also if you hit the menu button on the tv does this distortion affect the menu as well (this will also confirm an internal issue). It looks like the light engine (also known as an optical block.. this is what the lamp plugs into)or video processing board. Either could be the culprit and would be outrageously expensive to fix out of pocket.
