Possible Causes

Loose wiring harness between the UI and main control, Failed user interface board, Failed main control board.

Safety: Turn off power at the circuit breaker.

Check harness connections: Access the back of the control panel and verify that all multi-pin connectors between the user interface (display board) and the main control are fully seated.
Inspect harness: Look for pinched, cut, or burnt wires in the wiring harness bundle.
Test with power: After reseating the connectors, restore power and see if the display responds normally.
Board isolation: If possible, test by substituting a known-good UI or main control board. If not, visually inspect both boards for damage and replace the most likely failed board (often the UI if the display is dead or garbled).
