Ok - I actually have a 25 inch monitor that blew the main fuse in the game (not sure why - the main fuse on the chassis blew as well).

I have a spare I hooked up - and it works - but there is no blue. I put the color test on from a CPS2 board - and the screen shows no blue on the blue bar, and the 'white' looks yellow. The background is blue instead of black like it would normally be.

Does anyone have the flowchart? I know someone had one for download somewhere here, but all of my searching turned up squat. I know it is probably the driver circuit - but without a chart/etc, I can't find what to check.

Thanks.

You don't need a flowchart for color issues, they're really simple. You've either got a bad connection from your pcb up to the monitor, or you've got a bad transistor or potentiometer in the blue circuit on the monitor, or your tube is shot.

Have you seen blue on this tube, with another board hooked up to it?
