So I know it’s probably time to get a new tv but I like to fix things that are broken, if at all possible, instead of throwing them away. So my tv, which the model code is LN46A630M1FXZA, has an issue on start up. There is a screen issue when I turned it on and anything is plugged up to it. Not only does the screen go all haywire, with snow, lines, and color distortion, but the white noise sound blares! And it will turn on and off by itself until the problem goes away. Please Help!
Does this occur if you removed the connected external devices? Have you tried replacing the cables?
