Hi

i have this board from the above model , part number is 6-71-w24h0-d02a

it powers on but there is no backlight

i need schematic to see what voltage is missing from led screen connector

i check for fuse but there is no fuse near the connector

remove the screen and check voltages on screen pcb ( vled, pwm and bl_on ) if you dont have schematic..!!

Back lit require generally 19Volts, Blon(Backliton) 3volts,PWM inverter again 3Volts. please check on screen pcb if do not have the schematics of laptop PCB.
