Another posterity post: Fixed a 32" Funai LCD tv

Tv blacked out and made a high pitch squeeling sound.  Using a thermal camera, I opened the back and plugged in the set and saw that D139 (zener diode) was toasty red so I replaced it and the TV came back to life.  The offending part is a 1N4755A zener diode. cost me $.50 to repair.

In case anyone else has the same issue with this set...
