Possible Causes

Failed transformer, Blown internal fuse, Loose display ribbon cable, Defective control board

Safety first: Unplug the unit before opening the control housing.

Check transformer: Test or replace the AquaSoft 24V transformer if it is warm, discolored, or shows no output.
Inspect internal fuse: Some AquaSoft boards have a small fuse. Check and replace with the same rating if blown.
Reseat display cable: If the display is a separate module, reseat the ribbon cable between the display and main board.
Replace control board: If power is present at the board but the display remains blank, replace the main control board.
