I have a RCA 52"hdtv m#D52W17) It just went blank while watching it no sign nothing was wrong before hand. No sound No picture but power light is still on. when it happened it started making a popping noise like electric so I unplugged it when my husband came in I told him what happened so he looked at it and found where the popping was coming from. a black box at the edge of the computer board about 4in long and maybe 5in wide not part of board just attached to it it has a focus & a Screen nobs on it . What is it? and can we fix it @ home ? It is only 11 months old

My TV has just a bright line that runs across the middle of the screen.

that is the line output transformer. It sounds like it has shorted and will need replacing, possibly along with the line transistor.
