Labels and displays
Blank, damaged, or low-contrast display
Inspect the housing and screen for impact, liquid, cracks, or mounting stress. Confirm the model and label ID and check whether the platform reports a completed recent update. Compare the unit with another label of the same model in the same area.
Do not open the housing or attempt an unauthorized battery replacement. Provide clear front and rear photos, the label ID, model, delivery or installation date, and the troubleshooting already completed.
