OLED dies

In the past 6 months or so I’ve had two of the .96” yellow/blue OLED displays go dead. No apparent reason, they’re perking along just fine and then they’re blank and cannot be revived by any method I can find on Google. The hotspot PS is plugged in to a UPS/line filter of a reputable brand and nothing else on that circuit has problems, so I assume it’s not a power glitch. My PS provides all the amps the hotspot can drink. Jumbospot on Pi ZW, up 24/7.
Have others had hotspot OLEDs fail? Maybe its internal components have just had a hiccup and need a reset, and if so is there a way to revive them?
I switched to my Nextion screen and it’s fine. I realize the Nextion is on a different port so I can’t rule out a port failure for the OLED but I think it’s unlikely.

The oled screens don't like running on 5v they prefer 3.3v (although I'd say that you already know this)
