Just fixed this one with a friend. Found capacitor 2508 on PSU board to be high ESR. (100uF 16V.)
2 blinks is usually a 12V error, although on this set appears to code for 9V standby failure. The 9V line measured only 5.5V during the error. Once warmed up the 9V line measured around 7V at which point TV kicked into life with OK picture, some fuzziness.
Upon replacing the capacitor, 9V now measures 9.5V, and fuzziness is (mostly) gone, TV powers up with no issue.
Some maldischarge -- fixed by doing SM reset (figured some corrupt NVM for plasma panel config.) Adjusted the overly bright picture too. Pulls about 300W from the wall, pretty hungry. No fans. Fujitsu-Hitachi plasma panel with the Y-buffers bonded to the panel -- don't like it!
Will try and get a video up soon.
