"someone" spilled something on a laptop and now the screen is extremely dim, you have to shine a flashlight on it to see anything. I replaced the inverter, still no fix... then replaced the entire LCD screen, still doesn't work!! There is one more solution I'm trying and that is a flat cable that connects from the mobo to the screen (it didn't come with the new screen, so I used the old one) ... I'm hoping that's the problem.
But while I'm waiting for that to arrive, does anyone have any suggestions?

Re: Screen extremely dim
I think you should look at the sleep button on pin.When you close LCD it should push that pin down(Stanby or sleep pin).
When you press or it get stuck, this pin will block or not send voltage to inverter so that the light on monitor should go off or computer go to standy or sleep mode.Check this one.
best of luck,takecare

Recently a 3 year old VIzio TV I bought started having problems. The set would turn on normally for a few seconds then the picture would go dark with everything else operating normally including sound. Remembering a similar laptop computer problem I diagnosed previously, I immediately suspected a defective TV screen backlight. To verify this in your own TV, get a very bright flashlight and with the TV operating in the failed blank screen mode, shine the flash light into the blank screen from various angles and distance (including touching the screen). If the LCD is still operating, you'll see a dim motion in the flashlight's reflection, thus proving it is indeed a failed backlight.
Hi, Do this test for me. Turn laptop on. Get a flashlight and shine in on screen check for start screen. If there is life in. Then you know it is a screen problem. LCD light problem. If you are computer and electronic savy remove and or disasemble screen. If you are not take it to someone who can and repair.
Try shining a flashlight or a lamp on the screen and see if you can faintly see the Windows desktop in the background. If you can then the problem is the backlight. Laptop screens have a light that shines from behind the screen and lets you see the display. If this is a laptop computer it will need to go in for service. If this is a monitor for a desktop computer you can try turning it on and off a few times, or leave it unplugged for a few hours and try it again but failing that it also needs service.
