Troubleshooting Dim Laptop Screens

Depending on the generation of the laptop in question, there are a few reasons why your screen may be dim. But first let's define what a dim laptop screen really is. A dim laptop screen is when a laptop screen is so dim that you need an external lightsource to view it, however at the right angle or illumination it can be seen that it the laptop itself is outputting information to it, yet is not easily viewed without assistance

In order to properly diagnose a dim laptop screen we need to determine the type of Laptop Screen you have. There are two styles, the first style which was common until the last year or two is called the CCFL/Inverter style. This type of screen uses a compact fluorescent bulb (not the same as in our home lamps, but similar concept).

Or you could have what is called a LED Screen, Both Laptops use a liquid crystal displays or LCD as we commonly call them to display the information, however they are illuminated differently. A LED Based screen does not use an inverter based system since the voltages required are not near as high as they are for the CCFL based screen.

Alright, so take a minute and identify the type of screen you have, and then jump to the next part.

Troubleshooting Dim Laptop Screen on CCFL based laptop:

First you will need to remove the bezel, then you will find on the lower part of the screen a long thin circuit board that will be mounted to the back of the screen surround. Take this to a small computer repair shop, and ask if they have a used one you can buy for testing for around $10.00, or order a comparable part off of eBay they should cost less than $20.00 dollars in most cases. Spend money? Yes, because it will cost you significantly less then having any local computer store or Best Buy repair it for you.
