Replacing an inverter board on a laptop can be a tricky and expensive process. If the laptop screen is very dim but you can still make out the image, it's likely related to the inverter. However, it could also be due to a faulty backlight lamp, video cable, or even the motherboard. To replace the inverter board, you'll need to carefully lift it and turn it slightly.
The left side of the board connects to the video cable and the right side to the backlight bulb (CCFL tube) inside the LCD screen. Once you've removed the old inverter, you can replace it with a new one.Unfortunately, many people have found themselves in a situation where they've spent more than $250 on guesses that were wrong. To avoid this, it's important to do your research and learn as much as you can about your laptop before attempting any repairs. You may even be able to find a part for as little as $12 on eBay.
If you take the screen inverter to a repair shop, they may charge you up to $600 without even explaining what was wrong with it.In some cases, pressing the screen cable next to where the inverter is and opening and closing the screen can make it work again briefly. However, if this doesn't work or if the clips that keep the screen closed are broken and lodged in the switch, preventing the backlight from working, you may need to replace the inverter with one from another broken laptop.Replacing an inverter board on a laptop can be a difficult and costly process.
