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
Is this a good question?
