YouTube TV is displaying sound but no video — here's what's usually happening

When YouTube TV plays audio but the screen stays black or blank, the problem is almost always one of four things: your internet connection is too slow to stream video, your device's HDMI cable or connection is loose, your TV input is set to the wrong source, or YouTube TV's app needs to be restarted or updated. Start by checking these in order, because the first two account for the vast majority of no-picture calls.

The good news is that none of these require a technician. You can walk through each one yourself in about ten minutes.

Key Takeaways

  • A black screen with sound usually means your internet speed is below 3 Mbps for standard video or 25 Mbps for 4K, so run a speed test on the device that's streaming.
  • Check that your HDMI cable is fully seated in both the device and the TV, and that your TV's input is set to the correct HDMI port number.
  • Force-close the YouTube TV app completely and reopen it, which fixes most software glitches without losing your place in a show.
  • If you have a Chromecast or streaming device connected to your TV, make sure it is powered on and selected as the active input.
  • Restart your modem and router by unplugging them for 30 seconds, then plugging them back in, which clears temporary connection problems.

Check your internet speed first

YouTube TV needs a minimum of 3 Mbps to stream standard video without buffering. If you are watching 4K video, you need at least 25 Mbps. If your connection is slower than that, the app will play audio while it waits for video data to arrive, which looks like a black screen.

To test your speed, go to speedtest.net on the same device you are using to watch YouTube TV — not on your phone or computer. Run the test and look at the read speed number. If it is below 3 Mbps, your internet is the problem. Move the streaming device closer to your router, or ask your internet provider whether your plan includes the speed you are paying for.

If your speed is above 3 Mbps but you are still seeing a black screen, move to the next step.

Verify your HDMI cable and TV input

If you are using a streaming device like a Roku, Apple TV, or Amazon Fire Stick, the HDMI cable that connects it to your TV can come loose from either end. Unplug the HDMI cable from both the device and the TV, wait five seconds, and plug it back in firmly until you hear or feel a click. Do the same on the TV end.

Next, check that your TV is set to the correct input. Pick up your TV remote and look for a button labeled Input, Source, or HDMI. Press it and look at the list of inputs. The one your streaming device is plugged into should be highlighted or selected. If it is not, use the arrow buttons to select the right HDMI port and press Enter. Your picture should appear.

If you are streaming directly from a smart TV app (not through a separate device), skip this step — your TV does not have an input to switch.

Force-close and reopen the YouTube TV app

Software glitches often cause the video stream to fail while audio keeps playing. The fastest fix is to close the app completely and reopen it.

On most devices, press and hold the back button or home button until you see a list of open apps. Find YouTube TV and swipe it away or select "Close" or "Force Stop." Wait ten seconds, then open YouTube TV again from your home screen. The app will resume where you left off, and the picture should return.

On a smart TV, go to Settings, then Apps or Applications, find YouTube TV, and select "Force Stop" or "Clear Cache." Reopen the app from your home screen.

Restart your modem and router

A temporary glitch in your internet connection can cause video to fail while audio continues. Restarting your modem and router clears these glitches without affecting your settings or passwords.

Unplug your modem (the device your internet provider gave you) from the wall outlet. Wait 30 seconds. Plug it back in and wait two minutes for all the lights to stop blinking. Then unplug your router (the device that broadcasts WiFi) and wait 30 seconds. Plug it back in and wait another two minutes.

Once both devices have finished restarting, open YouTube TV again. If the problem was a temporary connection issue, your picture should return.

Update the YouTube TV app

If you have not updated YouTube TV in several weeks, an older version of the app can have bugs that cause video playback to fail. Check your device's app store — Google Play Store on Android, App Store on Apple devices, or the app store built into your streaming device.

Search for YouTube TV and look for an "Update" button. If you see one, tap it and wait for the update to finish. Reopen YouTube TV after the update completes.

Most devices can be set to update apps automatically, which prevents this problem in the future. In your device's settings, look for "Auto-update apps" or "Automatic app updates" and turn it on.

Check if your streaming device is powered on

If you are using a Chromecast, Apple TV, Roku, or Fire Stick, make sure the device itself is powered on and selected as your TV's active input. Some devices have a power button on the remote; others turn on automatically when you plug them in. If your device has a light on the front, it should be lit or blinking.

If the device appears to be off, check that its power cable is plugged in firmly. If it is plugged in but not turning on, try unplugging it for 30 seconds and plugging it back in. If it still does not power on, the device may have a hardware problem and may need to be replaced.

When to contact YouTube TV support

If you have worked through all the steps above and still see no picture, the problem may be with your account, your device's hardware, or YouTube TV's servers. Contact YouTube TV support through the app by going to Settings, then Help & Feedback, then Contact Us. You can also visit support.google.com/youtubetv and start a chat with a support agent.

Before you contact them, have ready: the name of the device you are using, your internet speed (from the speedtest.net result), and whether the problem happens on all channels or only some. This information helps the support agent narrow down the cause faster.

Frequently Asked Questions

Why do I have sound but no picture on YouTube TV?

The most common causes are slow internet (below 3 Mbps), a loose HDMI cable, your TV set to the wrong input, or the YouTube TV app needing to be restarted. Start by running a speed test on the device you are streaming from, then check your HDMI connection and TV input.

Can a bad HDMI cable cause no picture?

Yes. A loose HDMI connection is one of the top reasons for a black screen. Unplug and reseat the cable firmly on both ends. If reseating does not work, try a different HDMI cable if you have one available — the cable itself may be damaged.

Does YouTube TV work on WiFi or does it need to be wired?

YouTube TV works on both WiFi and wired ethernet. WiFi is fine as long as your read speed is at least 3 Mbps. If you are having picture problems and using WiFi, try moving your device closer to the router or switching to a wired connection if your device supports it.

What should I do if restarting the app does not fix the black screen?

Restart your modem and router next by unplugging them for 30 seconds each. If that does not work, check that your TV input is set correctly and that any HDMI cables are fully seated. If none of these steps restore the picture, contact YouTube TV support.

Can I watch YouTube TV on multiple devices at the same time?

YouTube TV allows simultaneous streaming on up to three devices on the same account, depending on your plan. If you are trying to watch on more devices than your plan allows, the extra streams will show a black screen. Check your account settings to see how many simultaneous streams you are may have access to to.
