Odd, that should all work fine. The Rev 9 is simply a PMIC change. You need an appropriate firmware but if you have tried Trixie that will already have it.
It might be a duff board.
What power supply are you using? Maybe its a bit on the edge.
I presume the Pi3B+ starts up and HDMI is working? It's only the DSI display that is not operating correctly?
