I moved roku from one tv to the other I see the light on but different inputs still show no signal

Yes, to get sound from your Roku TV to your receiver when using the TV's built-in apps (such as switching to TV sound), you might need more than just RCA cables. RCA cables only carry analog audio signals, and many modern devices, including Roku TVs, use digital audio signals for better quality.
Here's what you can do to ensure you're getting sound from your Roku TV to your receiver:

1. Check Audio Settings on Roku TV:
   • Go to your Roku TV's settings menu.
   • Look for the audio settings section.
   • Make sure the audio output is set to the correct option for your receiver. This is usually HDMI ARC (Audio Return Channel) or Optical audio.
2. Use HDMI Cable with ARC Support:
   • If your receiver and TV support HDMI ARC, connect an HDMI cable between the ARC HDMI port on your TV and the ARC HDMI port on your receiver.
   • Ensure that the HDMI input on your receiver corresponds to the HDMI ARC output on your TV.
   • In the TV's audio settings, select HDMI ARC as the audio output.
3. Use Optical Cable (if no HDMI ARC):
   • If your TV and receiver don't support HDMI ARC, you can use an optical audio cable (Toslink cable).
   • Connect one end of the optical cable to the optical audio output on your TV.
   • Connect the other end to the optical audio input on your receiver.
   • In the TV's audio settings, select optical audio as the audio output.
4. Configure Receiver Settings:
   • Ensure that your receiver is set to the correct input source for audio. For example, if you're using HDMI ARC, select the corresponding HDMI input on your receiver.
5. TV App and Volume Settings:
   • When using apps on your Roku TV, make sure the volume is turned up and not muted within the app itself.
   • Adjust the TV's volume settings to an appropriate level that allows your receiver to amplify the sound effectively.
6. Test with Different Content:
   • Test the setup with different apps on your Roku TV to ensure that the issue is not specific to a certain app.

If you've tried these steps and are still not getting sound from your Roku TV through your receiver, it's possible that there might be compatibility issues between your TV and receiver. You could also try reaching out to Roku's customer support or your receiver's manufacturer for further assistance.

Sounds like you have a bad connection on either your roku stick or your HDMI PORT.Does you ROKU stick show a white light if not check power cable or electrical plug.
Try wiggling ROKU stick just a hair or push it in and out until you get a signal..A purple screen with the words ROKU should show up on TV.If you have a bad port on TV it would have to be replaced but this is rare,if you have a second port on tv try that.Have you tried your ROKU stick on another tv?Does your streaming stick go in vertically or horizontally,if it goes in vertically it may be pressing against side of tv prohibiting a good connection.You could try a HDMI cable, plug the HDMI cable into tv and put ROKU in other side of cable.There is also a restart button on ROKU stick push it and it will start blinking,if it doesn't light up you may have a defective ROKU stick.

no remote makes it hard only way check if u have a menu button on the tv if u have it might open up youre AV ..........GOOD LUCK

One of your remotes probably has an input button , but if it does not then your tv should have a button on it to switch inputs. When you want to go back to watching regular tv, use the input button to switch back to the port where your tv signal goes into the tv.

Did you change the TV input setting on your TV to the correct HDMI input? Most Televisions will take a few seconds to scan the input before displaying any image. Most newer televisions have multiple HDMI inputs, and you might need to select each one, wait several seconds to see if there's a signal, and then move on to the next input, until you find which HDMI input has the Roku start screen signal.

On the back of the TV/VCR unit there is an input for audio & video plugs. These will accept a composite video signal and mono audio signal. I'm not sure if newer roku has these outputs as they are low def only signals. The roku would need to have have red, white & yellow sockets. (Old Roku's had these....) Yellow is video, red and white are L & R audio. Use a y adapter to merge red & white together, and use a standard RCA patch cord to connect the roku composite outputs to the TV VCR inputs.

Try moving the roku box around, they seem to be kind of fussy as far as picking up signal, I had the same issue but moved my box, ended up flipping it on its side and it works now.

We recommend you test the TV with a different source using the same cable connections. If the TV can display the image from a different source then the TV is fine. Please perform the same test by moving the Roku to a different TV.

MOST LIKELY the RF out put signal is the same as a local tv chanel 1) try menue change rf output suggest rf 68! OR connect av leads (red white yellow)from the output of your vcr and connect the other end to an Av input eg AV1 on your TV use tv remote to select the AV input
