I was reading this from another post and my U202 has 14V pin 8 and pin 6 = 5V.

The circuit that needs to be working is the one for U202/TR200, it supplies 12V_AC to get 12v_DC which supplies +12VCC_S which supplies Q212 and gives +5V_STBY
TR200 also supplies VCC_MAIN, Q216 is a switch that controls VCC that supplies U300 etc. Q216 is basically controled by ST_BY from the main baord.
So you need st_by ON signal from the main board to have VCC on U300
