Your problem could be a poor connection or part that is going out of spec somewhere that is causing the screen to go black and come back on. A bad solder could act intermittently like that. If the UPS is supposed to control the voltage and voltage fluctuations are what's causing it, then shouldn't the flicker stop completely?
