Back lighted screen but black, works on external video
I have a HP dv7 3089wm.
The screen will light up but black screen. External vga monitor shows normal. Not sure if I need a screen or inverter should there be one within the laptop. Suspect I need either screen or inverter. Could you please give me further info so I get right part. Thanks for you help.
I have checked the cable connection from screen to laptop. Unit seems to have one connector for backlight.and because it does light I assume that is good. Reset the cable from video to screen. Just not sure if unit has an inverter in laptop or if need new screen
Es esta una buena pregunta?
