Your Xbox Series X or Series S powers on, the light glows and the startup chime plays, but the TV says “No Signal” or stays black. A useful Xbox Series X no signal starting point is a full power cycle or the low-resolution boot in Fix #4. Common causes include the HDMI connection, an unsupported display mode, an intermediate device, or a hardware fault.
Quick Diagnosis: Is It the Console or the TV?
- Look at the front of the console. A lit Xbox button and startup chime show that the console has powered on, but do not prove that it finished booting. If the console won’t power on at all, you need a power fix instead, which this article doesn’t cover.
- Plug another device (a streaming stick or cable box) into the same TV input with the same HDMI cable.
- If that device shows a picture, the input works for that device’s video mode; the cable or display can still have trouble with the Xbox’s higher-bandwidth output.
- If that device also shows “No Signal,” the problem is the TV input, the cable, or the TV’s settings.
- Connect the Xbox directly to another known-good TV or monitor if possible. A picture there points toward the first display or connection; failure on both after cable and low-resolution tests needs Xbox Support.
- Write down what changed recently: a new TV, soundbar, receiver, cable, or a system update. That change usually points you to the right fix.

Error Messages Explained
These messages come from your TV or receiver, not the Xbox, so exact wording varies by brand.
| Message | What It Means | Where to Start |
|---|---|---|
| “No Signal” | The TV input isn’t receiving any usable video | Quick Diagnosis, Fix #1, Fix #2 |
| “Mode not supported” / “Unsupported signal” | The Xbox is sending a resolution or refresh rate the display won’t accept | Fix #4, Fix #5 |
| “HDCP error” or a black screen with sound | Copy protection failed somewhere in the HDMI chain, often at a receiver | Fix #7 |
Fixes, From Fastest to Hardware-Level
Fix #1: Power Cycle the Console and the TV
Symptoms: “No Signal” right after turning everything on, often after a power outage or wake from standby.
Why it happens: The console and TV negotiate video settings the moment they connect. If one side wakes up late or gets stuck mid-handshake, the TV never locks onto the signal. A full power cycle clears both sides.
- Press and hold the Xbox button on the front of the console for about 10 seconds until it shuts off.
- Unplug the console’s power cable.
- Turn off the TV and unplug it too.
- Wait at least 10 seconds.
- Plug the TV back in and turn it on first.
- Plug the console back in and press the Xbox button.
Verify: The Xbox logo or Home screen appears on the TV within about a minute.
Fix #2: Reseat the Cable and Check the TV Input
Symptoms: “No Signal” with no recent settings change, or the picture came back briefly after Fix #1 and then dropped.
Why it happens: A partly seated plug, or a TV set to the wrong input, looks exactly like a dead console.
- Unplug the HDMI cable from both the Xbox and the TV.
- Plug it firmly into the HDMI OUT port on the back of the Xbox. Series X and Series S each have one HDMI port, so there’s no wrong port on the console side.
- Plug the other end directly into a TV HDMI input, with no adapter or switch in between.
- Use the TV remote’s Input or Source button to select that exact input number.
- If there’s still no picture, move the cable to a different HDMI input on the TV and select that input.
- Power down and disconnect nonessential peripherals, including external storage, Storage Expansion Cards, and charging stations. Test with the power, HDMI, and any Ethernet cable connected; reconnect peripherals once an update completes.
Verify: The TV shows the Xbox Home screen on the new input.
Tip: Upgrading from an Xbox One? Those consoles also have an HDMI IN port for cable boxes. If you’re reusing an old setup, make sure the cable isn’t going into the wrong port.
Fix #3: Use an Ultra High Speed HDMI Cable and Remove Adapters
Symptoms: Picture drops at 4K or 120Hz, flickers, or shows sparkles, but a lower setting works.
Why it happens: 4K at 120Hz needs HDMI 2.1 bandwidth. An older “High Speed” cable from a previous console, a long cheap cable, or an HDMI adapter or switch often can’t carry it reliably.
- On Series X, use its included Ultra High Speed HDMI cable. On Series S, use a certified Ultra High Speed HDMI cable when attempting 4K at 120 Hz; do not treat the supplied cable as a substitute for this requirement.
- If that cable is lost or damaged, use a certified Ultra High Speed HDMI cable (the label and packaging say so).
- Remove any HDMI couplers, angle adapters, extenders, or switches between the Xbox and the TV.
- Keep the cable run short. Coil any extra length instead of buying a longer cable.
Verify: The picture holds steady for a few minutes on the Home screen without flicker.
Fix #4: Boot in Low-Resolution Mode (Power + Eject or Power + Pair)
Symptoms: The Xbox worked on your old TV but shows nothing on a new one, or it went black after a settings change or update.
Why it happens: The console keeps trying to send the last resolution and refresh rate it used. If your new display can’t accept that mode, you get a black screen. Low-resolution mode supplies a basic 640 × 480 signal. It can resolve an incompatible output setting, but cannot repair a bad cable, input, or HDMI port.
- Turn off the console by holding the Xbox button for about 10 seconds.
- On a disc-equipped Series X, remove any disc. Then press and hold the Xbox button and the Eject button together.
- On Series S, which has no disc drive, press and hold the Xbox button and the Pair button together. The Pair button is the small button on the front that you use to connect an Xbox Wireless Controller.
- Keep holding. You’ll hear one startup tone, then a second one about 10 seconds later.
- Keep holding until the second tone or until you see the console start in low-resolution mode. Microsoft documents this mode as 640 × 480.
These button instructions cover disc-equipped Series X and Series S. If your Series X has no Eject button, use Xbox Support’s model-specific help rather than trying an unavailable button.
Verify: With a working direct connection, a low-resolution picture should appear. If it does, continue to Fix #5; if not, test another cable and display before assuming the settings are responsible.
Fix #5: Set a Supported Resolution and Refresh Rate
Symptoms: You now have a picture (from Fix #4), or the picture disappears only when 4K or 120Hz is turned on.
Why it happens: This is the classic HDMI 2.1 4K120 mismatch. Many TVs support 4K at 120Hz on only one or two of their HDMI inputs. Receivers and soundbars often top out at 4K at 60Hz. If any link in the chain can’t handle the mode, the TV goes black.
- Press the Xbox button on your controller and go to Profile & system > Settings > General > TV & display options.
- Set Resolution to 1080p.
- Set Refresh rate to 60 Hz.
- Select Video modes and turn off Allow 4K, Allow 24 Hz, and Allow 50 Hz for now.
- Restart the console and confirm the picture holds.
- Turn settings back on one at a time: 4K first, then 120 Hz. Restart and check after each change.
- If the picture drops at 120 Hz, move the cable to your TV’s HDMI 2.1 input (check the TV manual or the label on the ports) and try again.
- If 4K or 120 Hz options are missing entirely, go to TV & display options > Video fidelity & overscan. Ensure Auto-detect (Recommended) is selected. Microsoft warns that 4K is unavailable when HDMI or DVI is selected manually.
Verify: In TV & display options, select 4K TV details to see which modes the console says your TV supports.
These are on-console menus with no web version. The Xbox Support 4K pages below cover the same requirements.
Fix #6: Turn Off VRR, ALLM, and HDR to Test the Handshake
Symptoms: The screen goes black for a second when a game launches, flickers during menus, or loses signal at random.
Why it happens: Variable Refresh Rate (VRR) changes the refresh rate constantly. Auto Low Latency Mode (ALLM) switches the TV into Game Mode automatically. HDR changes the signal format. Each switch is a mini-handshake, and some TVs and receivers fumble them.
- Go to Settings > General > TV & display options > Video modes.
- Turn off Allow variable refresh rate.
- Turn off Allow auto-low-latency mode.
- Turn off Allow HDR10 (and Auto HDR, if shown).
- Restart the console and test.
- On the TV, turn on the enhanced HDMI mode for the Xbox’s input. It’s called Input Signal Plus on Samsung, HDMI Ultra HD Deep Colour on LG, and Enhanced format on Sony.
- Turn each Xbox feature back on one at a time to find the one causing the drop.
Verify: The picture stays stable through a restart and a game launch with the feature set you leave turned on.
Fix #7: Bypass the Soundbar or AV Receiver
Symptoms: The picture works when the Xbox connects directly to the TV but not through a soundbar or AV receiver. You might hear sound with no picture, or see an “HDCP error.”
Why it happens: Passthrough devices must repeat the handshake and HDCP copy protection between the Xbox and TV. Microsoft notes that intermediate video equipment can interfere with the data passed between console and TV and must support the same capabilities.
- Unplug the Xbox’s HDMI cable from the receiver or soundbar.
- Plug it directly into the TV.
- If the picture returns, the passthrough device is the cause.
- Check the receiver or soundbar maker’s website for a firmware update and install it.
- If it still fails, keep the Xbox connected to the TV. Send audio to the soundbar or receiver through the TV’s eARC/ARC port instead.
Verify: Picture and audio both work with the new setup through several power cycles.
Fix #8: Update the TV Firmware and the Console
Symptoms: A black screen started after a system update, or a new TV never gets a picture at certain settings.
Why it happens: TV makers often patch HDMI 2.1 bugs after launch. On the Xbox side, an unfinished update can leave display output stuck.
- On the TV, open its settings menu and look for Software update or Firmware update. Install anything available.
- On the Xbox, go to Settings > System > Updates and install any pending console update.
- If a system update failed and you can see the Xbox Startup Troubleshooter, follow Microsoft’s advanced offline system update procedure. It requires a Windows PC with internet access and a USB port, plus a USB flash drive with at least 6 GB formatted as NTFS. Formatting erases the drive, so back it up first. Use the current official download and model-specific steps. If you cannot see even the troubleshooter, contact support instead of attempting recovery blindly.
Verify: In Settings > System > Updates, the console reports it’s up to date. You can compare the version with the latest release notes.
Fix #9: Reset the Console and Keep Your Games
Symptoms: A display setting keeps reverting or the black screen keeps coming back after every other fix.
Why it happens: A corrupted setting can survive restarts. A reset reinstalls the system software and clears settings without touching installed games.
Before resetting: Test another display and cable first. Confirm that your saves have synchronized to the Xbox network and that you know your sign-in details. A factory reset removes accounts, settings, and home-Xbox associations; anything not uploaded can be lost. “Keep my games & apps” preserves the installed games and apps, not your console setup. If you cannot confirm a backup of important local data, stop and contact support.
- Get a picture first using Fix #4.
- Go to Settings > System > Console info.
- Select Reset console.
- Select Reset and keep my games & apps. Don’t choose Reset and remove everything.
- Sign back in when the console restarts and set display options again using Fix #5.
Verify: The console boots straight to a picture on your normal input without the low-res trick.
When It’s Hardware: Bent HDMI Port Pins
If the signal cuts in and out when you touch the cable, or no cable works, inspect the port.
- Unplug the console completely.
- Shine a flashlight into the Xbox’s HDMI OUT port.
- Look for pins that are bent, flattened, pushed together, or missing. Check the plastic tab in the middle for cracks.
- Try one known-good Ultra High Speed HDMI cable as a final check.
Don’t try to straighten pins with a needle or tweezers. The pins are tiny and soldered to the motherboard, so prying at them can short the port or snap it off the board. Visible damage needs assessment by Xbox Device Support. Request service rather than assuming software changes or a specific replacement part will fix it.
Series X vs. Series S Differences
| Task | Series X | Series S |
|---|---|---|
| Low-resolution boot | Xbox button + Eject (disc-equipped model) | Xbox button + Pair |
| HDMI ports | One HDMI OUT | One HDMI OUT |
| Remove disc before boot combo | If equipped with a disc drive | Not applicable |
All the menu paths here are the same on both consoles.
Settings to Check
- Resolution: Settings > General > TV & display options. Start at 1080p and raise it only after the picture is stable.
- Refresh rate: Same menu. Use 60 Hz unless the TV input and cable support 120 Hz.
- Video modes: TV & display options > Video modes. Turn off Allow 4K, 24 Hz, 50 Hz, VRR, ALLM, and HDR10 while you test.
- Overrides: TV & display options > Video fidelity & overscan. Keep it on Auto-detect (Recommended) unless you’re forcing re-detection.
When to Escalate
Contact Xbox Support when:
- Low-resolution mode, a direct TV connection, and a known-good cable all fail.
- You can see bent pins or damage inside the HDMI port.
- The offline system update fails or the console won’t finish booting.
Before you reach out, note your console model, TV model and firmware version, what changed before the problem started, and which fixes you tried. Start at the Xbox Support get-help page, which routes you to chat or a Device Support repair request.
Prevention Tips
- Change one thing at a time: Raise resolution, refresh rate, or HDR in separate steps so you know which one broke the picture.
- Save your Ultra High Speed cable: Keep the original Xbox cable with the console rather than reusing an old one.
- Support the cable: Avoid tight bends or heavy cables hanging off the port, which strain the pins over time.
- Update before upgrading: Update TV and receiver firmware as soon as you install new gear.
Frequently Asked Questions
Why does my Xbox Series X turn on but my TV shows No Signal?
The console is running but the TV rejects its video, usually because of a loose cable, the wrong input, or an output mode the TV can’t handle. Start with Fix #1 and Fix #4.
What is the button combo to reset Xbox display settings?
With the console off, hold Xbox + Eject on a disc-equipped Series X, or Xbox + Pair on Series S, until the second tone or low-resolution startup. Microsoft documents 640 × 480 output. See Fix #4 for the model limitation.
Why did my Xbox lose signal after I got a new 4K or 120Hz TV?
The console is still sending the mode it used before, or it’s trying 4K120 on a TV input that doesn’t support HDMI 2.1. Use Fix #4, then set the mode in Fix #5.
Does the HDMI cable that came with my Xbox matter?
Yes. The Series X’s included Ultra High Speed cable is rated for 4K at 120Hz. Older High Speed cables often fail at that bandwidth.
Why does the picture disappear only when I turn on 4K or 120Hz?
Something in the chain can’t carry the extra bandwidth: the cable, the TV input, or a receiver. Try the TV’s HDMI 2.1 port and a direct connection.
Could my soundbar or receiver be causing the black screen?
Yes. Intermediate video equipment can interfere with the signal. Connect the Xbox directly to the TV to confirm, then see Fix #7.
How do I know if my HDMI port is physically damaged?
Look inside with a flashlight for bent or flattened pins. A signal that cuts out when you touch the cable is another sign.
Will resetting my console delete my games?
Not if you choose Reset and keep my games & apps. It leaves installed games in place, but removes accounts and settings. Sync saves first: unsynchronized local data can be lost.
