That is an old panel - try to look in the manual MA00571C or similar.
May be the panel is configured to adjust the backlight / contrast from block 997 in run mode, but that is restricted with a password (level 1 to 8). Or you need to go in programming mode and adjust the contrast
Something from this manual:
A/ Switch between programming, PROG, and run-time, RUN, by pressing the keys [<] and [MAIN] simultaneously. The possibility of switching between PROG and RUN from the operator terminal can be controlled with a password
B/ Applicable for Process Panel 210, Process Panel 220, Process Panel 320, Process Panel 325 and Process Panel 235:
The contrast settings are made in the programming mode under Setup/Contrast setting or in run mode through a jump to system block 997. By pressing on the function key + the display becomes brighter, and by pressing on - it becomes darker. Return to the previous level by pressing EXIT
