Hello,
Would any one be so kind to help with this issue that i'm facing, please.
A logicboard 820-3115 has green light on the charger and it turns on but there is no video.
I measured :
U9000 pin 2 and 3 have 3,42.
and LCD_IG_PWR_EN on pin 1 is missing.
L7510= 0.84v
L7520= 0.84v,
L7550 = 0.35v
USB mouse is lights up
J9000 on pin 4, 6 and 7 have 3.39v
checked resistance to ground on all LVDS_IG_A_DATA_ lines are between 1.2 and 2 ohms.
