| Often these errors are related to a bad solder joint on the main-pcb or crt-board.
You can check this by [b:5e367dc780]gentley[/b:5e367dc780] tapping on some parts on these pc's with an isolated screwdriver.
Whenever you tap, and the picture goes dark, you're sure it's a bad solder joint and you'll need to re-solder it.
