Need some help troublshooting this issue

Hope all is well everyone , long time.

in the span of a week , i had 3 seperate issues requiring repar in my truck camper , two are minor and easily fixable , but im having trouble with this

in this photo , you will see the main control panel in my RV , i use this to turn on my water pump , it also has a display to show the state of the blank and grey tanks and it also shows the battery voltage

Issue one:
- the display no longer displays anything , its just dark grey and wont show any picture
- the water pump will not turn on

I can turn on the porch light and the entry light , so those two lights do still have power and i can turn them on fully from the display , but the water pump will not turn on , and the display button itself will not show anything

I am without water not for weeks because of this and ive been too busy to rectify this but its starting to become a big problem now. Pls tell me your thoughts?

I think the pump might be bad because it froze up last month and i heart it kind of struggling to work, not sure if the pump and the display issue are related
