Took more time for visual inspection of the back of the power board and review voltage checks. Nothing obvious appears to be out of place or damaged. Read somewhere (forgot where) that no power after hearing power supply relay click means power supply board is bad. I can upload photos if needed. BTW... My situation is same as in this thread. but do not know the cause of failure as it failed while watching a movie. http://www.tv-forums.com/cgi-bin/gforum.cgi?post=161108;search_string=sony%20kdl;#161108

I have not been able to find an OEM board for this tv anywhere. Anyone have any ideas where to score one, have one repaired, or one that I can retro install? Surely there is a similar model that I can use that matches the display or something.

Thanks! I'll look to see if those numbers will help find something. Sure would like to reuse this thing, even if there was a universal display board out there like for laptop screens.
