Sometimes a television suddenly turns itself off and on again or restarts. This can have very different causes - the solutions to the problem are just as different. This article will tell you what to do in such a case.

Briefly disconnect the TV from the power supply

Often times, you can fix errors by turning off the TV and disconnecting it from the power supply. Wait about half a minute before reconnecting the TV and turning it on. Then check if the problem is still there.

Too many remote control commands?

If you press a lot of buttons on your remote control in quick succession, it can overwhelm the TV. The commands are stored in the television's memory and are then processed in sequence. If too many commands are cached, the TV can respond more slowly, freeze or restart. So wait for one command to run before giving the next one..

Sleep timer set?

Many devices have a sleep function that automatically switches them off after a certain period of time or goes into standby mode. Check the TV settings to see whether you have accidentally activated this function. If so, disable it.

Outdated software?

If your TV is a smart TV, the reason it automatically turns on and off may be due to outdated software. To update the software, you need to connect your TV to the internet. Then you can check for updates online..

Demanding or faulty app?

You can use apps on a smart TV, but they can also cause errors. If an app buffers a lot (e.g. a streaming app) and thus blocks the memory of the TV, this can cause the TV to restart. To prevent this from happening, make sure that your TV has a stable and fast internet connection.

Errors in apps can also cause the TV to restart. If you receive a corresponding error message, uninstall the faulty app.

Faulty device connected?

Many devices can be connected to your television, such as hard drives, DVD players or boxes. Errors in these devices can cause your TV to restart. To check this, unplug all devices from the TV. Then alternately connect a device to the television and observe whether it works normally.

Loose contact on the cable?

If the television switches itself on and off without connected devices, the cause may be an unstable power connection. To check, try other outlets. Also check the power cable and, if necessary, the multiple socket for loose connections. To do this, jerk the cable slightly, while watching the picture from the television, whether it jerks or flickers - this indicates a loose connection.

The last resort: contact customer service

If all of these tips don't help and your TV still turns itself on and off unintentionally, contact your TV manufacturer's customer service.
