my 60" sharp Aquos tv keeps turning off, many times I reset factory holding down switches and then works for a while then later on turn itself off again. I see some picture flickering or backlight flickering or if a dark screen between moments of tv picture will shut it off again. What part do I need to but and replace for this?
