Power Plant Premier display malfunction

Any suggestions on how to fix this display PCA board for my PS Audio Power Plant Premier? After it is powered down and unplugged for a period of time, then turned back on the entire display comes on with random flashing for a few seconds followed by most (not all) of the display going dark. PS Audio no longer services these and I can’t find a replacement display. I’m comfortable with soldering but not with diagnosing the problem. Could it be as easy as replacing one or all capacitors? Is the larger capacitor (might be slightly bulging on the top) the power supply cap?
