RCA 42PA30RQ Has sound, no picture

Troubleshooting TVs and Video Sources - Badcaps Forums - www.badcaps.net
Have a tv I'm working on. Powers on fine. Only shows random dots, not a whole picture. Does that for 30 sec or so then fades, no picture at all. TV stays on. Have seen on this board that may need to replace multiple boards. I would like to avoid replacing random boards. Here are some pics of the boards and what the tv does. I understand this is a Samsung that is notorious for issues like this. Power supply outputs are normal.
