Technical repair questions

I first heard a pop and then buzzing from the back side of the TV. At the same time the picture became fuzzy. The buzzing is coming from the "T503 FBT" flyback transformer. I assume that the FBT has gone bad, but is there another faulty part that could have caused the problem? Many thanks.

Your fly back is bad. the fuzziness is caused by the bad fly back. and soon you will lose the picture due to this fly back and might cause the horizantel transister to blow. change it as soon as possible. good luck

Plasma TV

If you mean the picture froze or formed fuzzy pixelated picture and crackling, this will be due to a poor aerial signal to the tv, but if you mean the screen rolls with pink/white patchwork type squares and shows the picture in the background, all be it fuzzy, then that's the same fault as I am getting and have had to report the fault to LG as I am on my second TV. If it is the problem mentioned in the first sentence, it is happening to our friends in OS and they have been told by specialist aerial fitters, the signal is too weak for the tv.
