What I know so far is the Horiz output is shorted or at least I think it's the HO, 3 legged heat sunk transistor near the Fly, probably gotta be the HO.
The fuse isn't blown, the diodes in the PS are OK but it won't turn on.
There is a heat sunk transistor in the power supply that's getting screaming hot even with the set not operating (but plugged in), also the main filter cap is getting hot but I can't tell if it's just radiant heat from the transistor heating it up (feels more like the heat's from the cap itself) BTW the red hot transistor isn't shorted!
there is a small Zener diode in the PS that MAY be shorted, reads .5 ohms but I need to disconnect it to be sure.
This probably isn't worth a whole lot of time but since it's only a year old I thought I'd take a crack at it.

You got to be kidding, trying to fix a Funai-made TV.
