Troubleshooting Your CommBox Product Before Contacting Support

Before logging a support ticket, try these simple troubleshooting steps that resolve most issues without needing technical help.

Applies to:

All CommBox Products

Step 1: Restart Your Device

  • Turn off the screen or display using the power button.

  • Unplug the device from the wall socket.

  • Wait 30 seconds, then plug it back in and turn it on.

🔁 A quick restart can resolve temporary glitches or unresponsive behaviour.

Step 2: Check Power and Connections

  • Ensure the power cable is firmly plugged in at both the device and the wall.

  • Check the power outlet by testing another device.

  • If using a wall bracket or AV cart, confirm nothing is loose or damaged.

🔌 Loose cables are a common cause of display issues.

Step 3: Update Firmware

  • Go to Settings > System > Firmware Update.

  • Check if an update is available and follow the prompts.

💡 Running the latest firmware keeps your display running smoothly and is required for warranty support.

🔗 Visit CommBox Firmware Support for instructions and downloads.

Step 4: Test the Display and Inputs

  • Try using a different HDMI or USB cable.

  • Switch to another HDMI port.

  • Try connecting another device (like a different laptop) to isolate the issue.

📺 If the issue is with the display signal, swapping cables or ports can help identify the problem.

Step 5: Check Network Settings (For Smart/Interactive Models)

  • Go to Settings > Network & Internet.

  • Ensure Wi-Fi is connected or Ethernet is plugged in.

  • Try toggling Wi-Fi off and on again.

🌐 A poor network connection may affect app access, updates, or remote support.

Step 6: Review Setup Guidelines

  • Confirm installation follows the recommended specifications (e.g. correct power supply, proper ventilation, and weight limits).

  • Remove any stickers, writing or permanent markers from the screen or bezel.

🧼 Tampering, incorrect installation, or damage can void your warranty.

Troubleshooting / What to Do If It Still Doesn’t Work

If the issue persists:

  • Gather your proof of purchase, product serial number, and photos/videos of the issue.

  • Log a ticket on the CommBox Support Portal.

  • CommBox Support will perform remote diagnosis before dispatching a technician or requesting a return.

🚨 DOA (Dead on Arrival) issues must be reported within 7–14 days.
