Fix a no-signal or connection error
A no-signal message does not always mean the television signal or service is down. First identify whether the TV, device, home internet or one app is affected.
1. Check the TV input
Confirm the television is set to the HDMI input used by your streaming device. Check that the device has power.
2. Check internet access
Open another trusted app or website on the same device. If nothing connects, investigate the home network first.
3. Restart in a safe order
Close the app. Restart the streaming device. If the whole home network is affected, restart the router using your ISP's instructions.
4. Check another app or title
If other apps work but one app does not, note the exact error and contact the app provider or service support.
5. Check official service notices
Look for a verified service announcement before repeatedly changing settings or reinstalling apps.
6. Contact support with useful details
Send your device model, app name, ISP, country, error text and the time the issue began. Hide usernames and other account details in screenshots.
Frequently asked questions
Why does my TV say No Signal?
The TV may be on the wrong HDMI input, or the connected device may not be powered or connected correctly.
Why does only one app show a connection error?
The issue may be specific to that app, its account configuration or its service provider.
Should I bypass a warning or network restriction?
No. Stop and verify the warning with the legitimate app or service provider. Do not bypass security or network restrictions.
