I am having the hardest time troubleshooting a Hitachi 50" plasma TV. The screen turns on displaying a picture then it turns off again. From what I know about Y-SUS and Y-Buffers, the screen fails to display anything in the respective area when one of those is bad. So what on earth would make the TV display a picture and then shut itself off? All the inside components and boards look perfect and the voltages all test correctly until it shuts itself off. This is driving me crazy.
