Full Discussion: Screen fading out and in.
Operating Systems Linux Ubuntu Screen fading out and in. Post 303003275 by Corona688 on Monday 11th of September 2017 01:49:00 PM

I have experienced this hardware issue in CRTs before. It can happen when the flyback transformer loses voltage due to shorting or from its driving transistors overheating. It happens most often when the screen is left on for long periods of time.

Try swapping in an LCD to see if the problem goes away.
