I have replaced a 19" Monochrome Arcade monitor chassis power supply (DBQ? I think) Not sure of the tube no stickers part numbers or model. With the WEI-YA 820H high Impedance, The monitor is high impedance 57 ohms. Running a Gaplus game board Vertical display. Tried all the adjustment picture is not bad, But the left side picture is small then going to the right the picture/ images get bigger, B+ about 120VDC adjusting has no effect on this. Anyone run across this before? Or any help advice appreciated. Thanks
