Samsugn PN60F5500AFXZA, dark screen with color speckles

Troubleshooting TVs and Video Sources - Badcaps Forums - www.badcaps.net
Hi everyone! The last time I worked on one of these, I had shutdown, but this time, it's acting like a bad X-Main; I'm wondering if anyone knows any tests I could do to confirm it? The pictures of this model's boards can be found here on the first post of this thread:

Haven't found any missing or low voltages, but haven't checked EVERYTHING. VS, VA, VE are good. TV has audio and when you bring up the menu or any OSD, it brings up all the colored speckles and distortions in that area of the screen. It looks like the typical X-main (Z-SUS) failure we see on all plasmas, but want to make sure....?
