Is everything normal with your alternator and batteries? I have had low voltage do that to me when I had a bad alternator. Could be the back-lighting for the lcd panel in the display too but that isn't as common as it used to be. Most of the LCD panels anymore use a LED backlight and those normally go for a long time.
