Hello, I have a Blast City here, everything is great only above left and below left corner the image is blurred and the colors are not correct. In addition, the image draws an arc upwards in the middle. Does anyone have an idea how I can fix this ? Thanks

Convergence strips and calibration. But it might be more trouble than it’s worth! This is very common on this monitor. You may find that when you boot a game, you can just adjust the height and width to clip off the distortions, and the playfield is still fine.

Most folks replace all the capacitors on the chassis before calibrating.

P.46 covers Factory Service mode, but you enter it by holding all three OSD buttons down (start with up/down then hit mode, then hold) for 3 seconds.
