TV flickering from Roku home screen to static and back

I am not tech savvy and the husband is out of town so I cannot provide most of the info requested but I’m desperate. Roku is my only access to streaming and we don’t have cable.

Tuesday night it was fine. Wednesday night every time I turn on the tv and hit the home button on my remote it flickers (every second) from home screen to white snowy static.

I have turned it off and on. It just does the same thing. I have unhooked it from the receiver and I tried switching it from HDMI 1 to 2 (read that worked for someone with a similar problem)


Roku is model 4400x
Serial 4U75A8320813

Thanks

Do you have your Roku directly connected to your TV with the HDMI cable now?

No the tv and the Roku are both connected to the receiver.

Try connecting the Roku directly to your TV with the HDMI cable and see if you still experience the issue. This will rule out whether the receiver is a problem or not.

You could also try unplugging the power cable from your Roku, Power off or unplug power from your receiver, then Power off your TV. Then, Power on your TV, then wait 30 seconds, Power on your receiver, then wait 30 seconds, then, plug the Power cable back into your Roku and allow it to power up and restart - Make sure everything is connected like it originally was before you do this though. This could refresh everything to where it is all working normally again.

I did all that. It flickered right through the Roku start up and continued on doing it. <<sigh>>

I appreciate your help

So, you also tried connecting your Roku directly to your TV with the HDMI cable? - When you do this, make sure you unplug the power cable from you Roku, then power off your TV before you connect the HDMI cable from the Roku directly to your TV. Then power on your TV and then plug the power cable back into your Roku and let it power back up to the Home Screen.

Mine does this too occasionally, someone on another thread with the same problem said that changing hdmi cables fixed it for them so you might give that a try and unplug/plug back in as Tonya G suggested after you connect the new cable. I haven't gotten around to trying a new cable with mine yet.
