Hi guys, this one just came in with very little signs of LD - the owner sais it was not spilled on. I UCed it before starting with it.
I measured:
LCDBKLT_EN_L to be HIGH which means Q7706 does not produce PPBUS_SW_BKL
LCD_PWR_EN is HIGH which means the LCD is detected (?)
Also PP5VR3V3_SW_LCD_ISNS is ok
PPVIN_S0_LCDBKLT at 13V
Also PP5V_S0_BKLTCTRL present at C7750 and R7743 - R7744.
There is continuity from R7700 to Pins 9 & 10 of U7701.
External monitor shows image without issues.
(Irrelevant question: This one turns on only when the battery is connected - is this normal behavior?)
Please kick me to the right direction. Or punch me or use a 9mm and aim the shoulder.
