Problems started a few months ago when a vertical line started appearing. Not visible during some screen colors/movements. A second line appeared about a month later. Two weeks after that the TV died. Power cycled and it would flash and a brief sound would come out then the blue power light would flash (five times). TV was re-set and re-powered and same flash and blue flashing. Protection mode I guess. I pretty sure the Hitachi heard me ordering a new Samsung while it was working and decided to die early.
OK, pulled the rear cover and snapped a few photos, inspected the caps and surprisingly did not find any bulging caps? Checked the only fuse I could find (on the PSC)
Inspected the buffers and did not see any obvious failures.
I'm going to start testing for shorts on the PSC tomorrow, then test for shorts on the buffer boards.

Any guidance would be appreciated!
