I have a Dell XPS m1210 that I've been using for almost 6 years now. Recently the LCD screen back light would turn on for a few seconds, then shut off until I closed the screen and opened it up again. Every time I would open it up the light would come on, then shut off. This would happen for the first few minutes I had the laptop on until whatever the problem component is would warm up and the light stays on.
What would be the most likely component here that's starting to fail?
