"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

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.
The image on your screen is made up of two parts the lcd screen that creates the image that you can see dimly and a backlight that shines trough the screen brightening it so you can easily read the screen. In your situation in would appear the backlight bulb is burnt out and needs to be replaced. If your handy this is something you could do yourself a search on google for "backlight" and your specific laptop model will bring up available replacement bulb and quite possible detailed instructions on how to replace
It is typically the display's backlight or inverter board.
If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim on you rather than a slow degradation the inverter would be indicated.
This can be a few things first see if the fans and hard drive are spinning. If neither is it normally means the motherboard has failed and needs to be replaced.
After that if both are on and spinning shine a flashlight on the screen. If you see a dim image of the desktop it means the back light had died and needs to be replaced.
If the image is not dim and both are on try connecting an external monitor to the laptop. If you don't see anything on the external monitor either it means the laptops video card has failed and needs to be replaced. However if you do see an image on the screen it means either the laptops LCD cable or the LCD itself needs to be replaced.
there is a inverter in LCd that makes your lcd bright white shine. when it breaks down you see black screen. something happens on lcd you cant see clearly you should go to service and need to be changed INVERTER.
