No sound on tv.All cAbles are correctly connected.Volume set on 70.Dstv cable connected correctly and sound settings on 90

RCA video cables handle analog signals. HDMI cables carry digital video signals. You need a converter. If you are using a component video converter, check if you swapped two of the three RCA video cables. (There are some A/V projectors that can do the translation of RCA and HDMI internally. Most TVs do not.)

I hope this helps.

(One of my family's TVs used a dongle to condense the analog video signal to a single port, swapping blue and green gave a black and white output, IIRC.)

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.

If you're not getting any sound from your DSTV decoder when connected to your Aim 60 Inch Digital UHD TV via HDMI, there are a few things you can try:

1. Check your TV settings: Make sure that your TV's audio settings are set correctly. Check that the volume is turned up and that the TV speakers are not muted or turned off. Also, make sure that the TV is set to receive audio through the HDMI input.
2. Check your DSTV settings: Make sure that your DSTV decoder is set to output audio through the HDMI connection. You can usually check this in the settings menu on the decoder.
3. Try a different HDMI input: If you have other HDMI inputs on your TV, try connecting the DSTV decoder to a different one to see if the problem persists. This will help to narrow down whether the issue is with the HDMI input on your TV or with the DSTV decoder.
4. Try a different HDMI cable: Even if you think your HDMI cable is fine, it's possible that there is an issue with it that is causing the sound problem. Try a different HDMI cable to see if that resolves the issue.

If none of these steps solve the issue, it's possible that there is a problem with the HDMI input on your TV. In that case, you may need to contact Aim customer support for further assistance or consider bringing the TV to a repair shop.

It may have been set in to mute mode, check it out through your remote. If you have done this and found that it is not, it may be on the cables.
Pull out all cable that is connected and pull it in again one by one and try to hear if sound is being restored.

Set your TV to Input 1 or 2 depending on the port you used. PLease but your volume will be only controlled via DVD, if you switch your TV off it will still sound the TV channels via DVD speakers,

If your TV has a headphone socket, then plug the speakers into there, then (you have to do this for some TVs, but not others), go into the set-up menu and turn the headphone volume to 70%. Switch on the Z4 and sound should come out, assuming all connections are correct.

Check the cable box volume. Most boxes allow you to adjust the volume from the box to the TV, and most likely it's gotten turned down. Use the "Volume" control on the cable box to bring the level back up. (Unless the box remote has been set up for RCA, it controls the box volume. Once you get the volume back up, follow the cable provider's instructions for setting the remote to control an RCA. Then the volume control will function correctly.)

These are the answers straight from the dell manual. Ensure that the audio cables are firmly connected to both the audio input connectors on your LCD TV and audio output connectors on your PC or Video player. If on certain TV channels you receive a picture but no sound, this means that you do not have the correct TV system. Modify the SYSTEM setting. Check if TV volume is turn off of muted Connect the audio cable securely Audio cable is connected incorrectly Verify that the audio source is selected correctly in the OSD
