Re: sharp lc52d62u LCD TV no 12V coming out of PSU all other voltages ok
Also i thought 12V was the trigger to kick on the inverter boards not TCON but i could be wrong
IC5702 is KIA 378R12PI
other pinout on psu board connect small one is as follows
PD cn5703
PS_ON pin 1 2.91v
AC_DET pin2 3,3v
GND pin3 0V
PNL_POW pin4 0V
BU5V pin5 4.98v
GND pin6 0v
also on main board 4pin connector that goes to inverter to trigger on has no voltage, but i suspect this is due to Main board not racing 12V power on
