New display suggestion

[RebelPrinter]

Can Somebody suggest a new display ? I have 2 different controller both giving communication errors to an S866 display. One controller is a KT36/48 and the other is a generic 24/36/48 26a. The problem with this display is I am locked out of the higher functions. I can get at P1-9, but above that cant get in. I've tried M and +, M and -, both + and - and all 3 buttons. Nothing unlocks it to get at the higher P settings. I hate to have to buy a complete kit and sell these parts to get everything matched if a new display will do the trick. I have found the settings to get the issues resolved, I just cant get at them. (Set P20 to "0")

This setup is something I have cobbled together as finances allowed. Bafang G020 front drive, 52v 16aH batter with Samsung cells, and generic throttle/brake.controller/display off of Amazon.CA. I do need one with the flat connector, not the round juliette-style.

Displays aren’t compatible across brands. If have a KT controller, use a KT display.
The S866 is compatible with brainpower or JN controllers, but firmware may differ, so best purchased as well a set (controller and display).
