I think it's too big. I just replaced a ton of caps in mine and I replaced c5257 with Digikey part # P13524-ND. It's a 330u but it fits perfectly and is more than enough to rid you of buzzing. The 7.5 mm lead spacing is key if you want it to sit flush to the board.

I think it will be fine. I don't actually think it's that critical. 330uf or higher, and don't get a cheapy.

The buzzing...this is audible buzzing right (as opposed to video noise). A lot of times when the XG is displaying a bright scene it will buzz...would replacing some caps fix this?

Sorry, when I say "too big" I mean it's physically too big (10mm lead spacing). Mark is right... 470u is no magic number but try to get close to that. Remember, these things did work with a 10u in there

Nautikal, a full white screen is when the pj is being driven hardest so a power supply line capacitor somewhere is a likely candidate. Maybe an XG expert could give you some suggestions?

Are you sure? 10mm lead spacing will pop right into the old holes - a perfect fit.
