Hi, I know not many people have this tv, but I'll ask the question since Thompson/RCA has been NO help. While watching my RCA F38310 38" HDTV the screen went black. No display of any kind (no menu, can't view vcr or dvd). All I can see are 3 short vertical lines in the middle of the tv that are green, red & blue. It powers up, the fan that runs constantly is still running, but no pic or sound. I spoke with 1 tv tech who said most parts for this tv are not available. I wonder if I should waste time & money trying to fix it. $80 just to come to my house & look at it. Too heavy to take to store. Thanks in advance for all advice!
