laptop screen dim

by makatoka / June 24, 2012 8:22 AM PDT

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!

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.

Bob didn't say "Let HP fix it free". He said "Let HP fix it". If there's no warranty you have to pay for it. Buying another laptop isn't free either. Your choice, based on a quote from a repair service.

I didn't mention a free fix.

But given I'm seeing similar or better laptops for 399 here, I'd move slowly and get an estimate.

external monitor. If the display is fine to the external screen you can eliminate it being a mobo problem.

I have similar problem

I have a HP pavilion dv9700t laptop screen problem that is very dark but can see shadows of the desktop.

When I turn on the computer and Windows starts up the laptop screen will turn on for one second. I can see the desk top fine and normal, it then goes back to being very dim. I think some people think when they have this problem and call it a black screen but it may not be. My screen is also black but if up shine a flash light on it you can see the desk top detail fine. It is just VERY dark. The brighting switch/mode does not efect it. I don't believe it is the lid switch because the lid is always open and not moved.

I can connect externally to TV ok. That tells me the graphic chip and drivers are ok.

I replaced the inverter and lamps with OEM parts. I tested them with my screen before final connect to the mother board and are ok.

I use the function F4 to switch between the TV and laptop display. The laptop will display for one second again and go very dim. That tells me the lamps are working and screen is okay.

I've done the pull battery and power down as some suggest with no luck.

I've went into the power option and set the display to never turn off plugged in or on battery mode.

I see on computer forum sites that others have had the dim screen problem but I haven't seen a solution yet. I am wonder if it might be a register glitch for the display, or a key board problem.
Anyone have the same scenario and found the problem?

one thing I should have done when this stated was to look and see if any updats were installed that might have a conflict with the graphic drivers. I've have re-installed previous display dirver with no luck, but is could be some other update that has caused the problem.

Then using the restore media will push it all back to stock and you know to not accept updates next time.
