weak or no signal when turning on tv suddenly. This never happened before.

Suddenly tonight I am getting no signal or weak signal and a black fuzzy screen.

 

This has never happened before while using my  Roku.  I have had to reboot a number of times, but afterwards Roku always started.  I rebooted everything, but am getting the same message.

Any advice.

Here's what has worked for me.

  • Restart your router (even if other devices have no problem finding and connecting). Sometimes that's all it takes, if not keep going.
  • Restart the Roku to clear its memory via Settings > System > System restart (for a Roku TV it's Settings > System > Power > System restart). Again sometimes that's all it takes, if not keep going.
  • Find and connect to your network via Settings> Network > Set up connection

If that doesn't fix it, try disconnecting the power to your Roku for a few seconds.  When it comes back up, see if you then can set up the network connection.

Second thing to check:

A neighbor may have started up a wifi network on the same channel you are using, causing interference.  Try logging into your router control panel and changing your channel to see if you can find one less congested.
