Hello: I have a Mitsubishi 45" PTV Model # VS-45603 Chassis # VZ5 in my shop which has a convergence problem. The convergence is off Horizontally and vertically in all areas of the raster for all colors. The customer
menu convergence adjustments do not move the crosshairs in any direction for any color. I am not familiar with this chassis and don't have service data for it. I have data and experience on the VZ2 chassis.
This VZ5 chassis uses 2 STK392-110 ICs mounted on a board on the left side (As viewed from the rear) of the plastic tray. The signal board is in the middle, and the deflection/PS board is on the right. I have a data sheet on the STK392-110s from Sanyo, but I don't knwo what the proper voltages are for the pins. What are the common causes of this problem? Also, I would appreciate a scan of the convergence schematics
and powers supplies for the convergence circuitry. Thank You!
