Roku TVs No Signal: How to Fix It Yourself
A 'No Signal' message on a Roku TV means the TV is working fine — it just can't find anything to display on the selected input. This is almost always a cable issue, a wrong input selection, or the connected device needs a restart. You can fix this in a few minutes.
⚠️ Safety First
- Make sure connected devices are powered off before unplugging HDMI cables.

Step-by-Step Repair
- 1
Make sure you're on the right input
Press the Home button on your Roku remote to go back to the Roku home screen. If the home screen shows up, the TV is fine — you're just on the wrong input. Navigate to the correct input (HDMI 1, HDMI 2, etc.) that matches where your cable box, console, or streaming device is plugged in. Check the back of the TV to confirm which port you're using.
- 2
Reseat all HDMI cables
Unplug the HDMI cable from both the TV and the connected device (cable box, game console, etc.). Wait 10 seconds, then plug both ends back in firmly. Make sure the cable clicks in and isn't loose. Try a different HDMI port on the TV if the first one doesn't work.
- 3
Restart the connected device
Power off whatever device you're trying to watch (cable box, Roku stick, PlayStation, etc.). Unplug it from power for 30 seconds, then plug it back in. Many 'No Signal' issues are actually caused by the source device freezing up, not the TV itself. Wait for it to fully boot before checking again.
- 4
Restart the Roku TV itself
Go to Settings > System > Power > System Restart on the Roku menu. If you can't access the menu, unplug the TV for 60 seconds and plug it back in. After it restarts, navigate to the correct input. If you're still seeing 'No Signal,' try a different HDMI cable — cheap cables fail more often than you'd think.
If That Didn't Work
- A bad HDMI cable that looks fine but has a broken wire inside
- The connected device's HDMI output resolution is set higher than the TV supports
- A firmware bug — check for Roku system updates under Settings > System > System Update
When to Call a Professional
If you've tried multiple cables, ports, and devices, and the TV shows 'No Signal' on every HDMI input, the TV's HDMI board may be faulty. This is uncommon but can happen after a power surge. A professional repair would run $80-$150, so compare that to the cost of a new Roku TV.
