I previously posted help request with this monitor when it was in my Ms Pac machine. I finally pulled it out of the cabinet and put it on my bench for the ease of troubleshooting. I am running it with a Golden Tee 3D machine. I believe I have isolated it to the vert out section. I have checked every Oscilliscope point listed in the Manual, and several dc measurements on various transistors. The attached picture is what the screen is doing, (disregard the Ms. Pac Bezel.) The biggest 2 problems I have found is the collector on Q302 (even though the schematic calls it Q203) is about 15 volts higher than the manual calls for. R313 is measuring 470 ohms. TP 82 (wire going into green deflection yoke) appears to be overdriven and inverted.
Any help putting me in the right direction would be awesome.
Thanks
