¶ Issue
After powering on the device, double-tapping the screen does not show a QR code for activation and the screen remains blank.
¶ Solution
-
Power off the device before opening the armrest.
-
Open the armrest containing the screen module.
-
Disconnect all three cables inside, then reconnect them securely.
-
Use the image below to confirm that each cable is properly seated:
- Two cables have clips. Ensure that each clip hooks securely onto its connector.
- Push the third cable fully into its connector. When properly seated, the blue rubber seal should no longer be visible.
-
Close the armrest, power on the device, and check whether the QR code appears.

¶ Why This Happens
One or more of the three cables inside the armrest is not fully connected, so the screen module cannot display the activation QR code.
