XBR960 static issue: failing capacitor?

I'm having an issue with my XBR960. The picture, no matter what the source is, has a layer of static/noise over it. Depending on the brightness, contrast, etc. some settings make it more visible while others make it blend in to the picture more, but no matter what it causes eyestrain and makes the picture look worse. I've been trying to research what could be causing this problem and the only the thing I can find is a possible failing capacitor. (Source: http://shmups.system11.org/viewtopic.php?f=6&t=43091) Money is not an issue so if I need to replace a capacitor I have no problem with that, however I would first want to know if that's definitely what needs to be done to make the static go away and also which capacitor I would need to replace. All help is appreciated.

Changing HDPT does not affect it. I really don't know how to go about solving this problem so I really need some guidance. What steps should I take to figure out what component of the TV is causing the problem? Or is this something that can be fixed in the service menu?
