hello i have a notebook hp g62 and i have a problem with it is a model with i3 processor and ati hd 5470 and i have a problem with it wen i turn it on the back light just opens a half of a second at start and then is off and doesn'tt comes on i measure it with a multimeter on the lvds at screen at pin 35 witch is dim control and i fount a 0 volt on it actually the functioning of it is from 0.7 volt to 2.5 volt so 0.7 v is wen display is low brightness and 2.5 v wen is on full and i measure the pin 36 witch is pwm on backlight and has 3.3 volt on it so if i can get a bit of help with a illumination circuit datasheet i will be very thankfully or the cip witch controls illumination and i have bot it with no lcd so i have a 15.6 led full hd display witch i want to mount on it but it sees the 1920x1080 resolution but look's like some pixels are missing and is going to a white trend and i am very curios if some one has done this before and what do i need for it just a lvds with all wires attached or some other parts to attach on motherboard? I hope a technician from service or some qualified personal can answer's me to my question.
