The laptop came shorted...dont know history.
+ac_bat_sys line was shorted to gnd. Had to replace charge manace ic, both mosfets,
Then i found shorted on gpu gtx 1050 and also on U8005 short. i replaced both.
now i have picture but only on hdmi, nothing on lcd.
Then i found that on lcd_vcc i have only 1,8V, so i replaced U4501 and resistor R4502...and now on lcd_vcc i have 3,2 V...but again no picture on lcd.
On lcd_bken_con i have only 0,3V and when i plug and unplug charger i can see little flicker on the screen.
Help me where to look next?
Boardview attached, but its little strange..you have to flip it horizontaly in boardview...When you open it, just click wiew/flip board horizontaly so it will give you correct image.
