50 inch Plasma TV picture goes out (Arlington)

Samsung 50 inch Plasma TV that works normal initially and then the picture will stop working but the sound continues. The TV can work completely normal for hours and then other times after 1hr and then the picture goes out, but sound continues as normal.
The pictures will return with turning the TV off and then back on again. This TV could be good for parts or if you know how to fix it.
Thanks
