Hello,
I need help with Nm-B661 mainboard.
PU3501 was burned and changed with new one. I am now able to turn on laptop but without picture on display - no image no backlight and nothing on +LCDVDD_CON.
Display connected to hdmi works fine.
For me it looks like +3VS line - i can measure only around 1.9-2V.
+LCDVDD is connected to U9 (SY6288C)...and i have on INput again 1.9V and on EN i have 3.3V...but nothing on OUTput
.....and no touchpad too...but is again powered from +3VS.
*measured without connected display cable
please help
