Roku Error Code 029 — HDMI Signal Lost

What Does This Error Mean?

Roku error 029 means the Roku device has lost its HDMI connection to the TV. This happens when the HDMI signal drops out — due to a loose cable, a TV input switch, or the TV briefly losing power. The Roku detected the screen went dark and reported the disconnection. This is usually a quick fix: check the cable and make sure the TV is on the correct input.

Common Causes

HDMI cable is loose at the TV or at the Roku device
TV was switched to a different input (another device or antenna) and the Roku input was deselected
HDMI cable is damaged or has a bent pin
TV briefly lost power (power blink from utility) and reset the HDMI connection
Roku Streaming Stick loosely seated in the TV's HDMI port, causing intermittent signal drops

How to Fix It

Press the Input or Source button on your TV remote and make sure the TV is set to the HDMI input where your Roku is connected. The TV may have been switched to a different input (cable box, game console, etc.) and the Roku input was deselected.

If you have multiple HDMI devices, it's easy to accidentally land on the wrong input. Cycle through each HDMI input until you see the Roku home screen.
Unplug the HDMI cable from both ends. Check the cable's gold connectors for any bent pins or visible damage. Plug it back in firmly at both ends — you should feel slight resistance when fully seated. A loose cable is the most common cause of 029.

For Roku Streaming Sticks plugged directly into the TV's HDMI port: press the stick firmly into the port until it's fully seated. A barely-seated stick will intermittently drop signal.
Try a different HDMI port on your TV. TV HDMI ports can develop connection quality issues over time from plugging and unplugging cables. A different port often resolves intermittent signal issues.

Label the port you use with a small sticker ('ROKU' for example) to prevent accidentally switching inputs in the future.
Test with a different HDMI cable. HDMI cables can fail internally without visible damage. Borrow a cable you know works, or buy an inexpensive replacement. A new cable is the most common fix for recurring 029 errors that aren't caused by a switched input.

HDMI cable quality matters more at 4K than at 1080p. If you're running 4K content, use a Premium High Speed HDMI cable.
If you have a Roku Streaming Stick and the HDMI port on your TV is tight or recessed, use the HDMI extension cable that comes in the Roku box. This positions the stick away from the TV and prevents physical strain on the HDMI port connection.

The extension cable also improves Wi-Fi signal quality for stick-style Rokus by positioning them away from the TV's metal chassis, which can block Wi-Fi signals.

When to Call a Professional

Error 029 never requires a technician. It's a physical connection issue between the Roku and TV. A new HDMI cable costs under $10 and solves most 029 errors.

Frequently Asked Questions

Why does error 029 happen randomly when I haven't touched anything?

Brief power fluctuations (even a fraction of a second) can cause an HDMI handshake to drop and need to restart. This is more common in areas with unstable power. A UPS (uninterruptible power supply) or surge protector with power conditioning can help prevent this. Also, some TVs power down HDMI inputs they detect as inactive to save energy — check your TV's 'Auto Input Switch' or HDMI power settings.

Could a power strip cause error 029?

Indirectly yes — a poor quality power strip that allows brief interruptions can cause the TV's HDMI negotiation to reset. A cheap power strip also provides no surge protection. Use a quality surge protector with a joule rating of at least 1000J for your entertainment setup.

My Roku Streaming Stick shows 029 and falls out of the HDMI port. What do I do?

This means the HDMI port on your TV has worn out and no longer grips the stick firmly. Use the included HDMI extension cable — it plugs into the TV's port and provides a secure, stable connection for the stick. The extension cable relieves stress on the port and usually fully resolves the problem.
