@kred sounds like a bad IP board (power board) Remove the back off your TV after unplugging it, then check the power board for any leaky or domed looking capacitors. Repalce those. Once you open your TV's back cover take lots of pictures and post those with your question. Use this guide for that, it will allow us to see what you see.

@kred what is the exact model of your TV? When the picture goes dark with no sound, does it come back on by itself? Do you have to restart the TV?

Model LNT3232hx. After 6-9 min picture comes back on then goes blank again, etc. the tv power light stays on and we can't manually or remote power it off. Tv
