I got this plasma and a spare identical parts unit. The parts unit had been dropped after it suffered the same problem as the good unit. Problem is when I got the unit powers on to blank screen with green light. After much doing and a suggestion from someone. I removed the units with the heat sinks from on sustain board and placed them on a scan board. This got a picture that is 3 pixels tall to display. Nothing else. So my question is: What should I try next? I read the post about bad capacitors. If I had bad capacitors shouldn't I have about half the screen? Or could I maybe have a bad capacitor in each pair? Using an oscilloscope I can see on the positive side of the capacitors I have 170V to ground but not necessarily to the negative side of the capacitor. There is no ripple in the wave of the voltage.
