Oops, I had to scroll the window to see it, yes that's another big blue....
No idea, is that standard according to the manual?
BR is _selling_ those things......
YES they _can_ be bad, but I haven't found a bad one....which doesn't mean it's a bad thing to replace them preventively....but there is also no need to "howl with the wolves" as we say....it's not like a "magic trick" that solves all problems.
In fact, I don't believe that much in blindly replacing a big blue anymore (or any other caps). Get out your fluke, put it in AC Voltage setting and measure across the big blue's terminals (powered on of course). Tell me what you see and I tell you if it's bad or not.
The monitors you cap-kitted had obvious problems. But if you have a nice working monitor, why bother ? f.i. the MB monitor is great, and I replaced one cap....
Etienne is right: The big blue is filtering the power that runs to the game PCB's. The width of the monitor has little to do with that. The monitor is supplied with 110V.
However, of course it _is_ possible that video circuits on a game PCB are influenced by a badly filtered supply voltage (when a big blue is bad f.i.) and that could cause weird problems on the screen, but not that the width is simply too large.
The thing is: check the basics first. The width of an (old) monitor cannot be adjusted with a pot, there is almost always the width-coil for that. The monitor manual/schematics should point you where it is...
