Kiosk
Why is the side UX display blank?
Restore a blank Side UX screen by checking power indicators, reseating the HDMI and Display Power cables inside the Side UX, and power cycling the kiosk.
📋 Overview
If the Side UX screen on the kiosk is completely blank or black, the most common causes are a power issue, a loose HDMI cable, or a loose Display Power USB cable inside the Side UX housing. Work through these checks in order — most cases resolve at Step 1 or Step 2 without needing a full power cycle.
Step 1. Ensure the Kiosk & Screen Are On
- Check the circle on the back of the kiosk — it should be lit up either blue or green.
- Check the power switch on the back of the Side UX — it should be set to the ON (I) position.
Step 2. Reseat Display HDMI & USB Cables
- Reseat the Side UX HDMI cable on the back of the kiosk (usually the top HDMI cable) — unplug it for a few seconds and plug it back in.
- Use the silver latch on the back of the Side UX to open the cover.
- Inside the Side UX, reseat the HDMI cable.
- Reseat the USB cable labeled "Display Power".
Step 3. Power Cycle the Kiosk
If the screen is still blank after reseating cables, fully power cycle the kiosk. Follow the steps in How do I power cycle the kiosk?.
💡 Tips
- The HDMI cable on the back of the kiosk is usually the top one of the pair — trace the cable to the Side UX to confirm before reseating.
- A blue light means the kiosk is asleep; press a key on the customer-facing display to wake it before troubleshooting further.
- If reseating cables doesn't help and the kiosk power indicator is dark, the kiosk itself isn't getting power — check the wall outlet and power strip first.
