Common Reasons Aloha Touchscreens Fail
- Terminal frozen or overloaded
- Touchscreen cable loose or damaged
- Grease/moisture interfering with touch
- Touch controller/driver malfunction
- BOH sync stalled, causing UI to freeze
- Physical cracks or dead zones
How to Fix Aloha Touchscreen Issues
1. Reboot the Terminal
A fresh restart clears memory issues and reloads drivers.
- Fully shut down the terminal
- Wait ~10 seconds
- Restart and test touches
If the screen responds normally afterward → it was software-related.
2. Clean the Touchscreen Surface
Grease, moisture, & objects leaning on the screen can trigger false touches.
- Wipe gently with a soft cloth (no harsh chemicals)
- Remove order tickets or utensils resting on screen edges
If response improves → interference was the issue.
3. Check Touchscreen Cable/Connections
Cables can become loose from bumps, cleaning, or vibration.
- Ensure USB/serial cable is fully seated
- Inspect for bent pins or frayed insulation
Loose connections can cause intermittent or no response.
4. Try External Keyboard/Mouse
Helps determine if issue is touchscreen-specific or system-wide.
- Connect a USB mouse/keyboard
- Navigate screens to test responsiveness
If mouse works but touch doesn’t → hardware or driver fault.
5. Inspect Screen for Cracks or Flicker
Visible damage usually means component failure.
- Look for cracks, cloudiness, or dark spots
- Check if touch fails in a specific “dead zone”
Physical damage requires repair/replacement — not software fixes.
6. Restart BOH Services (If Multiple Screens Freeze)
If several terminals freeze together → BOH is likely overloading.
- Restart Aloha BOH services
- Verify server CPU & memory load
Sometimes the UI stalls because data isn’t syncing properly.
When to Contact Aloha Support
- Touchscreen is completely unresponsive after reboot
- Display shows cracks, lines, or flickering
- Cables repeatedly disconnect/fail
- Driver updates won’t restore touch function
