Restore reliable touch quickly, so teaching and collaboration stay uninterrupted.

Applies To
Applies to: CommBox Interactive Neo (CBIN65, CBIN75, CBIN86)

Step-by-Step Instructions

Step 1

If touch fails on the home screen, check whether the screen is locked. If a lock message appears, unlock it. 

Step 2

If touch fails when a laptop is connected, confirm the USB touch connection is in place:

  • USB-C connection, or

  • HDMI plus USB-B (Touch) cable. 

Step 3

Restart the Neo and the connected computer. 

Step 4

Remove infrared interference sources (some lamps and lighting can impact touch performance) and test again. 

Step 5

Check for upgrades and update firmware if available. 

💡 Tip: Correct cabling plus a quick restart resolves most touch issues fast.

Troubleshooting / What to Do If It Doesn’t Work

  • If touch is intermittent or the pointer is inaccurate, remove USB extenders and keep USB cable length within 3 metres. 

  • If pen writing does not work but finger touch does, confirm you are using a CommBox Neo pen. If the issue continues, log a ticket on the Support Portal at Knowledge Base so CommBox Support can help with next steps.
