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)

I have the same problem with my Oled its totally dead, have not even had it a month and after a few nights of displaying its gone totally dead. I thought it might be something to do with my soldering, tried desoldering and cleaning up the old joint before soldering again with no joy have even gone as far as reflashing the sdcard with a new downlad of pi-star, this has not made any difference at all, so looks like the Oled is destined for the bin.
