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


    • 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!

Sounds like it could be a component on the motherboard/power from the motherboard. You did very well with your troubleshooting being able to rule out the screen itself and the video card.

thank you, but do need help on this...
