No output or backlight ever coming on
screen.
Power is off or not
making it to the door.
1. Open the access panel on the back of the door and
look for power indicator lights.
2. There is a slot in the back top of the door. If power
is confirmed, the display could have been turned off.
The power button can be pressed through the access
slot.
3. Check the door power harness (white 2-pin Molex
connector on the right side of the door) and verify
that wire routing and end connections are not faulty
or somehow disconnected. Use an ohmmeter to
verify continuity in the wire(s) and/or a multimeter to
measure 12VDC across the wires for power.

Use switch to turn display ON.
Flavor card is incorrect for the flavor in
