![]() ![]() This will mean that it’s working but the position needs to be adjusted so that the light diffuses evenly. If the lamp is not situated like that, the light will pour directly into the LCD which is not what we want. The lamp should be in front of the layer behind the LCD since the layer spreads the light across the screen. Electrical tapes are the most suitable for this assurance. The backlight carries high voltage so it’s of the utmost importance to make sure that it’s properly shielded. Now it’s connected to the new CCFL tube and the broken tube is no longer a part of the laptop. ![]() Use the wire crimping tubes to bind the wiring from the old lamp to the new one. Once you have spotted the inverter, attach a CCFL tube to it to observe if it lights it up. The inverter can either be inside the laptop or behind the screen. It is connected to the inverter which is covered. To do this, you need to fully remove the LCD assembly. The process to do this is different for every laptop but you will have to get to the bottom edge where the lamp is located. These tools are affordable and easily available in the market. For this, you will need the following materials at your side: In most cases, the backlight of a laptop is a cold-cathode fluorescent lamp which is also known as CCFL. They will only show themselves if you squint your eyes and watch very closely. They will be guarded by a screen as black as a pitch. The contents of the texts on the screen won’t appear to you. If your inverter is working just fine, you will see a dark screen instead of a reddish one. Now, you can proceed to replace the backlight with the method as follows: It is now crystal clear that the inverter is not at fault. The screen only becomes pink if it’s the backlight that needs to be fixed. However, if the button isn’t stuck and you’re able to get the screen to turn on, if only for a second, and witness the screen not dull but giving off a pinkish hue so that means that the problem is not with the inverter board but with the backlight. If the switch is dirty, it probably gets stuck inside and the power is cut off from the inverter board as an inevitable result. It’s vital in the sense that when pressed, this button enables sleep mode and the screen immediately goes black. This button is small and present close to the LCD screen. The backlight gets affixed with the inverter so if the inverter has given way then the backlight wouldn’t light up either.īefore doing that, take a brief minute to check the lid close switch. The screen is dim often means that the problem is with the inverter. ![]()
