I am working on this 51? projection TV in the home. I brought the main chassis back to my shop to work on it. It has 3 different problems. The picture goes dark intermittently. The picture also pulsates vertically every so often as well. These first 2 problems do not occur at the same time. The third problem is the red convergence is off about 1 inch all over the picture. I fed put a cross-hatch pattern into the TV and the red was off all over the screen. I can find no bad connections on the vertical or convergence circuits. Does anyone have a service manual and tips for this beast? TIA.
