touched the screen with a testpen and it lights up....its not static. is it monitor or could it be power supply?
The CRT "Daq" should be grounded. The CRT is coated with a conductive material (black material you see from the back) which usualy has a spring surrounding the tube. This spring has a wire connected to it. That wire goes to the ground (line cord) either directly or through a low value resistance. Check continuity from the "Daq" to the ground prong of the line cord. Also check the wall receptical for a good ground!
