🏢 Overview

If your TV or display screen is not turning on, showing no signal, or not displaying the connected device, don’t worry — most of these issues can be resolved with a few simple checks.
This article will guide you through the steps to identify and fix common display-related problems before raising or escalating a support ticket.

⚙️ Step-by-Step Troubleshooting Guide

🔌 1. Check Power Connection

Possible Issue:
The TV might not be getting power.

What to Do:

1. Confirm that the power cable is securely connected to both the TV and the wall socket.

2. Check if the wall power switch is turned ON.

3. Look for a small LED light on the TV (usually red or white). If there’s no light, try another power outlet.

💡 If the TV is connected to a power controller or sequencer (used in meeting rooms), ensure that system is powered ON.

🖥️ 2. Check for “No Signal” or Black Screen

Possible Issue:
The TV is ON but not detecting the input source.

What to Do:

1. Using the TV remote, press the Input / Source button.

2. Select the correct input (HDMI 1, HDMI 2, etc.) based on where your device is connected.

3. Check that the HDMI cable is properly plugged in at both ends — TV and device (like PC, media player, or VC system).

4. If still blank, try switching the HDMI cable or testing with another device.

🔊 3. TV Turns On, But No Sound

Possible Issue:
Audio settings or source issue.

What to Do:

1. Increase the volume using the TV remote.

2. Check if the Mute button was pressed accidentally.

3. If using a conference system, ensure the sound output is set to “HDMI” or the correct speaker source.

📡 4. TV Connected to Controller or Touch Panel (No Response)

Possible Issue:
The AV controller (Crestron, Extron, Logitech Tap, etc.) might not be sending the power command.

What to Do:

1. Try turning the TV ON manually with its remote or power button.

2. If that works, the control system may need to be rebooted.

3. Restart the control processor or touch panel (if accessible).

🧰 If your setup includes multiple devices (like matrix switchers or video bars), restart the entire system in sequence — controller → switcher → TV.

🌐 5. Network or Casting Display Not Working

Possible Issue:
Wi-Fi or LAN connectivity problem.

What to Do:

1. Ensure the TV is connected to your office network (wired or wireless).

2. Check if other network devices in the room are working.

3. Restart the TV and rejoin the Wi-Fi.

🔄 Quick Restart Tip

Sometimes, a simple power cycle fixes many issues:

1. Turn off the TV and unplug it from power.

2. Wait for 30 seconds.

3. Plug it back in and turn it on again.

🧯 Still Not Working?

If none of the above steps solve the issue:

• Note down the TV brand, model number, and issue description.

• Take a quick photo of the TV screen (if it shows any message).

• Submit a ticket via your Customer Portal or contact our team.
