Are posts about how to test the backlight. I can't tell if you own the right gear but if you don't it's time to consider letting HP fix it.
I own an HP laptop, model Pavillion g6. The screen is extremely dim, I can really only see the screen and icons when holding a flashlight to the screen. I connected the laptop to an external monitor, works perfectly, so video card should be ok. Checked all display properties, brightness, etc. Did my research, this is what I have done thus far:
1. Replaced LCD screen with new LCD screen, same result
2. Re-installed old screen again
the laptop do not have any inverter
3. Installed new LCD display cable, same result
2. - Could there be an error with the motherboard?
Is there any display fuse on the laptop motherboard? Not on the LCD!
ANY HELP/SUGGESTIONS WOULD BE GREATLY APPRECIATED!
