It is hard to lay out the layers flat again when the CCFL Tube is replaced so there might be some uneven lighting after the CCFL Tube is replacedДЄfter replacing the parts, turn on the computer again and the screen should be bright again.

Watch out for dust that could get in between the layers in the LCD (will show up as black specs under the screen.

It is difficult to take the part out of the LCD panel.

Here are some things to watch out for when replacing the CCFL Tube: Replacing these parts is an involved process will take at least one hour. This is cheaper than the $300 that Dell charges for shipping the laptop, buying the components and the labour. One source for parts is Ebay, but it might take around three weeks for the part to arrive.

Replace the problematic parts individually вЂ“ costs less (~$5 вЂ“ $20), but more difficult labour.

Once the cause has been determined, the next step is to replace the part. The bottom picture shows the Inverter by itself. The Inverter is the part in orange in the top photo. However, if one has a dim display but has checked whether the CCFL works, one can be more certain that the Inverter is the culprit by process of elimination. It isnвЂ™t possible to test this part directly without the proper tools (see this website). If the CCFL Tube lights up, then there is nothing wrong with the CCFL Tube. One can also test the CCFL Tube, by turning on the computer with everything still plugged in (but disassembled). If burn marks are not apparent, then the cause is likely due to the Inverter. Visual inspection of this part can sometimes show clear signs of damage. It involves opening the LCD panel (see this website for instructions for a Dell Inspiron 1520). CCFL TubeДЇinding the CCFL Tube on the laptop is a lot more involved than finding the Inverter. The second image shows the disassembled LCD assembly with the CCFL tube lying on top. The first image shows the laptop with the cover taken off. Different sized screws get used for different places and it is very easy to forget which ones go where. During disassembly, take note of what screws go where. Refer to instructions specific to the laptop in question to open up the screen assembly. It is not possible to to determine which part is the culprit without opening up the laptop. If one simply sees a dim display, it is due to either the CCFL tube or the Inverter. Some exceptions are when one has turned the brightness all the way down, but this usually isnвЂ™t the case for people. In general, if one experiences at least one of the problems above, there is a clear hardware issue. The CCFL tube burns out and leaves a dim display. The first problem tends to lead to the second one. Shining a bright light (such as a desk lamp) illuminates the screen slightly, but not to the brightness that the screen was at before.

Dim screen вЂ“ the LCD is still displaying a picture, but it cannot be seen because there is no backlight.

In some cases, the black triangle can change size over time (on the order of a few minutes or hours). The black corner is also hot to the touch. The mouse can be moved under it, which shows that the LCD is just not displaying that part of the screen. Black corner вЂ“ on one corner of the screen, a black triangle can be seen.In problems regarding a laptop display, these are the common problems among others that are quite prevalent among laptop users. The following instructions are general and do not pertain to one specific model of laptops. LCD Inverter вЂ“ transfers power to the CCFL lamp.The LCD panel provides the image, and the lamp provides the light required to see the image. CCFL Tube/Lamp вЂ“ provides the light on the display.LCD Panel вЂ“ the part of the assembly that displays the images and is what people are looking at when using the laptop.

The following is a list of the primary components and their purpose: The LCD assembly is a collection of components that allows the laptop to display things on the screen. After about three years or more of laptop use, one of the components that is likely to break is something in the LCD assembly.
