Why Does My Roku Say No Signal?

Find out which screen is missing

A separate Roku player sends video to the TV through HDMI. A Roku TV creates its own Home screen, even when a cable box or another device on an HDMI input has stopped sending video. First identify which screen still works; that tells you which device to test.

For a separate player, we'd start with the TV input. Roku calls the TV input the most common issue when a separate player has no picture; also check for a loose HDMI connection or insufficient player power. A failed cable, TV port or device becomes more likely after those checks. If the Roku Home screen appears but shows buffer, that's a streaming problem. If a Roku TV has sound but no picture from its own screen, use the Roku TV screen checks.

Get the picture from a separate player

Use this path when your Roku is a separate player or a Streaming Stick and the TV can still show its own menus. Stop when the Roku Home screen appears, then turn the TV off and back on once to make sure the picture returns.

1. Turn on the TV and press a button on the Roku remote to wake the player. If its Home screen appears, the TV is receiving video; test the next TV startup.
2. Read the HDMI number printed beside the port holding the player’s cable or Stick. Use the TV remote’s Input or Source button to select that number. If the button cycles through inputs, pause about 10 seconds on each. The Roku Home screen means you’ve found the working input; if the matching input still says “No Signal,” continue.
3. Unplug and firmly reconnect both ends of a box-style player’s HDMI cable. For a Streaming Stick, reseat the Stick in the TV’s HDMI port. Select that port again. A restored picture points to the connection; a blank input sends you to the cable and port tests.
4. If the player uses a removable HDMI cable, replace it temporarily with one that works for another video source. A stable Roku picture means the original cable needs replacing. Otherwise, move the player to another TV HDMI port and select that port’s number. If the new port works, compare the original port with another source.

The input matches, but the player still has no picture

Power is the next test when the matching input and a firm HDMI connection still produce no picture, or when the player restarts as the TV turns on. A flashing red player light or an on-screen low-power warning points toward insufficient power. A solid red light signals a different problem: overheating.

If the player gets power from the TV’s USB port, connect its supplied USB cable and wall adapter to an outlet. If it came without an adapter and shows a low-power warning, try a 5 V, 1 A USB wall adapter; confirm the rating on your player’s label. Select the matching HDMI input and wait for the Roku Home screen. If it stays visible through a TV off-and-on cycle, the USB supply was interrupting or limiting power. For more on a low-power warning, see why Roku says low power.

If stable wall power doesn’t restore the picture, unplug the player’s power for at least 10 seconds, reconnect it and select its HDMI input again. If the Home screen remains missing, test the player on another TV.

The Roku TV works, but its HDMI tile says “No Signal”

Press Home on the Roku TV remote first. A visible Home screen tells you the TV can display its built-in picture, so concentrate on the external device, its cable and the selected port. Use the HDMI number printed beside that device’s plug to choose the matching tile.

1. Turn on or wake the cable box, console or other device connected to that HDMI port. Select its matching HDMI tile. If its picture appears, the input is working; if “No Signal” remains, continue.
2. At the external device and TV, pull out the HDMI plugs and push them firmly back in. If the picture returns, the connection was loose. If it does not, try a cable known to work with another source, then another TV port and its matching tile.
3. Test a second working video source on the original port. If the second source displays a picture, investigate the first device or its cable. If several working sources fail on that port but work on other ports, that TV input is the leading suspect.
4. If the cable and source comparisons leave the result unclear, unplug the Roku TV for at least 10 seconds, reconnect it and restart the external device. Select its HDMI tile again. If the picture stays missing, keep the port-by-port results for the repair decision.

A system restart keeps the TV’s settings. If its built-in Home screen also fails to appear, the fault extends beyond that HDMI input.

5. If a known-working source still has a blank picture after the restart, and the Roku TV offers HDMI mode, press Home and open Settings > Inputs. Choose the failing input, open HDMI mode and try Auto. Retest the source; a picture that stays visible means that input setting works.
6. If Auto leaves an older source blank, try Compatibility. For a newer 4K HDR source, try Standard. Return to Home between changes so you can select another mode if the picture disappears. Retest each failing port because HDMI mode is set per input.
7. If known-working sources still fail, open Home > Settings > System > Software update > Check Now. Install an offered update while keeping the TV powered, let it restart, then retest each port with a known-working source and cable. A restored picture ends the checks; persistent failures go to the repair decision.

The picture works directly but disappears through a soundbar or receiver

A routed picture needs a video-capable HDMI path: player to the audio device’s HDMI IN, then its HDMI OUT to a TV HDMI input. A soundbar connected only through ARC or eARC has an audio return link, not an HDMI video input for the player. Connect the player to the TV in that setup. The HDMI eARC explanation (opens in a new tab) describes the TV-to-soundbar audio path.

1. Connect the player directly to the TV and select its HDMI input. If the Roku Home screen stays visible, the player and direct TV path work; reconnect the audio device one link at a time.
2. Connect the player to the audio device’s HDMI IN and its HDMI OUT to the TV. Select the player’s input on the audio device and the TV input receiving its output. A picture now points to a selection or connection that was wrong.
3. If the routed picture is still missing, firmly reseat each HDMI cable. Swap the player-to-audio-device cable with a known-working one and retest, then swap the audio-device-to-TV cable and retest. The swap that restores the picture identifies the bad link.
4. Unplug power from the player, audio device and TV for at least 10 seconds, then reconnect them and select both inputs again. If direct video stays stable but routed video still fails, keep the direct connection and report the input, output and cable tests to the audio device maker.

The player works on another TV

Connect the player directly to a second TV with stable power and a known-working cable, then select the HDMI input matching its port. Compare that result with the original TV.

If the Roku picture appears briefly on the original TV or disappears at one display setting, its chosen resolution or frame rate may be more than that TV can show. On the working TV, press Home and open Settings > Display type. Choose Auto detect first, then reconnect the player to the original TV. If Auto fails and the original TV supports 1080p, reconnect the player to the working TV, select 1080p and confirm the test picture there, then retest on the original TV. Confirm a manual choice only when you can see its test picture; an unsupported choice reverts after about 20 seconds. Roku’s display-type instructions (opens in a new tab) show that confirmation step.

What the final comparisons mean for repair

A player that fails on two TVs with known-working connections and stable power is ready for Roku support. For an eligible Roku-made player originally sold in the United States, request a return number from Roku support and have its purchase source, serial number and proof of purchase ready. A routed-only failure belongs with the soundbar or receiver maker. For a Roku-made TV, use Roku support; for another maker’s Roku TV, find its warranty contact under Home > Settings > System > About > Roku TV support before paying for service.

Repair of one failed physical HDMI connector is estimated at $100 to $350 installed. An installed standard main-board replacement is estimated at $200 to $450. The installed ranges include the part and fitting; diagnosis and a home visit may be charged separately.

Initial TV diagnosis runs $75 to $150, and a home visit may be extra. Some shops credit the diagnostic fee toward an approved repair. TV size, board compatibility and the local labor rate move the quote, so get an itemized total before approving the work.

If the player still has no picture after the connection and power checks, contact Roku support and check warranty eligibility before deciding whether to replace it. Compare a TV repair quote with an equivalent new TV before authorizing a board replacement.

Tell support or the repair shop whether the player worked on a second TV, whether other sources worked on the suspect port, and whether a direct connection worked when the receiver route failed. Have the purchase date and warranty status ready.
