Need Help troubleshoot this board.
DOE40-HSW DDR3 12314-1

Problem is no display, All voltages on coil are present except PL5101, PL8201, PL8202
I use different schematic (little bit different but some ic same) for tracing problem.
What i found :

- PL5101 : 0v ? ( no short )
- PL8201 & PL8202 / VGA_Core : 0v ?
- U8301 : - 1D05V_VGA_S0 & 3V3_AON_S0 missing

I already change PU5102 (SY8208CQ) and

Here's schematic i use

Let's see.
What is the voltage (to ground) of PU5102 chip pin1 and pin2 ?
Pin1 is EN when it is high it turns the chip on.
Pin2 is PG it shows if the chip output is good.
