Treadmill: Why does my treadmill have no display?
A bad console display, wiring failure or bad motor control board can prevent the display from lighting up.
Unplug the treadmill and check the wire harness connection between the console display and the motor control board. Reconnect any loose wires. If the wire harness connection is okay, you'll likely need to replace the console display. If the problem continues, replace the motor control board because the motor control board won't power up the console display.
