A power cycle can work wonders when dealing with various electronic devices, including your Hisense Roku TV. This process effectively clears the TV’s cache and refreshes its system. Here’s how to power cycle your Hisense Roku TV:

  1. Make sure your TV is powered on, and then turn it off using either your remote or the TV’s power button.
  2. After turning off the TV, unplug it directly from the power outlet. This step is essential to ensure a complete power cycle.
  3. Leave the TV unplugged for about 30 seconds. This pause allows any residual power in the TV’s capacitors to drain completely.
  4. After the 30-second wait, plug your TV back into the power source.
  5. Once your Hisense Roku TV is plugged in and connected to power, turn it on using the TV’s power button or your remote.

3. Adjusting Audio Output Mode

Adjusting Hisense Roku TV Audio Output Mode

Sometimes, the audio output settings on your Hisense Roku TV can lead to volume problems. By default, Roku TVs are set to auto-detect the output mode, whether you’re using the TV’s internal speakers or an external soundbar.

However, this automatic detection may fail, resulting in sound issues. To manually adjust the audio output mode, follow these steps:

  1. Access the Roku Settings: Using your Roku remote, navigate to the Roku settings. You can do this by pressing the Home button, scrolling down to the settings option, and selecting it.
  2. Select “Audio”: Within the settings menu, look for the “Audio” option, and select it.
  3. Adjust the Audio Output Mode: Under the “Audio” settings, locate the “Audio Output” option. By default, it may be set to “Audio Detect.” Change this setting to “PCM-Stereo.”
  4. Test the Sound: After making this adjustment, test the volume on your TV to see if the issue is resolved. If the problem persists, you can also try switching to other available audio output options, such as “Auto passthrough.”

By manually configuring the audio output mode, you ensure that your TV is using the correct audio format, which can often resolve sound-related problems on Hisense Roku TVs.

4. Checking HDMI and Audio Cables

Sometimes, the “Hisense Roku TV no sound when turned on” issue can be caused by faulty or improperly connected HDMI and audio cables. If you’re using external devices like gaming consoles, Blu-ray players, or soundbars, it’s crucial to ensure that the cables are in good condition and correctly plugged in.

Begin by examining all HDMI and audio cables connected to your Hisense Roku TV. Look for any visible damage, such as damaged wires or loose connectors. If you find any issues, consider replacing the damaged cables with new ones.

Even if the cables appear fine, sometimes they can become slightly loose over time. Carefully unplug and then firmly re-seat all HDMI and audio cables on both your TV and the connected devices. Ensure they are securely connected to the correct ports.

After re-seating the cables, restart all the external devices you have connected to your Hisense Roku TV, such as your cable box, game console, or soundbar. This can help re-establish the HDMI and audio connections.

Ensure that your TV is set to the correct input source for the device you want to use. Use your Roku remote to cycle through the available inputs until you reach the one where your device is connected.

Play audio or video content from the connected device to check if the audio is now working correctly on your Hisense Roku TV.
