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.
