did the phone charge when you put charger? if it's charge just focus on switch and line from it...maybe resistor is bad or line is weak....try to jumper the line or change the power switch.....

When conect charge, nothing. Not charge. I check line and resistor, I have 3.8 V on swich, and I try direct conect from resistor to gnd (drop to 0V), no power up.
Only power up when conect flash device and change mode, from local to normal.
