Hello all,
I am currently working on a WG6100 and have an issue with half the screen missing, specifically the top side of the Y-Axis on the monitor (Using standard orientation meaning X-axis is the long one and Y-axis is the short one).
To date I have installed a Ian Kellogg Total Rebuild kit (less frame transistors as he was out at the time), I have tested all the frame transistors at the P-connectors and they are fine.
By connecting my oscilloscope to the X and Y outputs on the game PCB I am able to see a complete picture so I believe that the issue is in the Y-axis circuit of the deflection board but not really sure what it may be. I have measured voltage on P600, Pin 1 as 26v and on Pin 7 as -26v, only thing that seems slightly out was on Pins 4 and 5 I measured 1v instead of the .05v
Please see attached photos for reference, any help would be greatly appreciated.
