Calm, step-by-step troubleshooting
Most everyday television problems have simple, safe explanations. Work through the relevant steps below at your own pace — there is no need to rush, and nothing here will put your television at risk.
Before you start
A gentle restart — switching the television off, waiting a minute, and switching it back on — resolves a surprising number of issues. It is a safe first step for almost any problem on this page.
No picture
- Confirm the television is powered on and any standby light behaves as expected.
- Press the input or source button and select the correct HDMI input for your device.
- Check that cables are firmly connected at both ends.
- Restart the television, then try again.
No sound
- Check the volume level and make sure mute is off.
- If you use a soundbar or external speakers, confirm the audio output is set to that device.
- Try a different app or input to see whether the issue is limited to one source.
- Restart the television and any connected sound device.
Our sound settings guide explains output options in more detail.
Slow menus
Menus can feel sluggish when storage is low or many apps are running.
- Restart the television to clear temporary data.
- Remove apps you no longer use to free storage (see apps & entertainment).
- Check for a software update in the built-in menu.
App freezing
- Close the app fully and reopen it.
- Check your connection, since many apps rely on a steady network.
- Make sure the app is up to date through the built-in store.
- Restart the television if the app still misbehaves.
Remote not responding
- Replace the batteries with a fresh pair.
- Ensure a clear line of sight to the television.
- Restart the television using the button on the set itself.
- Re-pair the remote using the television's built-in instructions if it connects wirelessly.
More detail is in our remote guides.
Wi-Fi connection problems
- Check whether other devices can reach the internet.
- Restart the router and the television.
- Re-enter the Wi-Fi password if needed.
- Improve router placement or try a wired connection.
See the connectivity guides for placement and signal tips.
HDMI source problems
If a connected device does not appear, the television is usually on the wrong input. Press the input or source button and choose the socket the device is plugged into. Try a different HDMI port or reseat the cable if the problem continues.
Audio synchronisation
When sound and picture drift out of step, look for an “Audio delay” or “A/V sync” setting and adjust it in small steps until speech matches lip movements. Restarting the television and sound device first often resolves it.
Picture quality issues
If the picture looks soft or blocky, it is often the source or connection rather than the television. Check that the app's quality setting is appropriate, confirm your connection is steady, and review the picture settings guide for mode and motion options.
A note on your safety
A genuine television problem will never send a message claiming your device is infected, hacked, blocked, or in danger, and will never ask for passwords, payment, or PINs to “fix” it. If you ever see something like that, do not follow it. The safe steps above, or the manufacturer's official support, are all you need.
