Good Evening: Nice little tv, Check out the schematic there are more than those
2 power supply points available for the different parts of this tv to use.

Could be other than power supply problem, but you gotta look, It don't seem
like it's on long enough to be a heat problem, also you gotta snoop around.
Good Luck.
