What part of the LCD panel assembly might be responsible for the LCD panel showing dim screens?
The backlight lamp. This is not an easy part to get to, takes time and if a mistake is made you could damage the screen beyond repair. Options, - Find a repair shop. Buy same model from say eBay with working screen. Buy a book with detailed info and pictures on repair. It would be simpler to replace a whole screen with backlight bulb. You can easily find your model number and order a new screen on-line (it is normally within $50-150 depending on model)
