My Samsung tv will power on and sometimes the screen will work and sometimes it will be pitch black, but either way I have audio and everything else seems to work. Sometimes it works for 1 min and sometimes hours, and other times I turn it on and already a black screen. I have removed the board and need to figure out what part to replace if possible, thanks
