We have searched and found some common reasons leading to this issue. Then, we devised solutions depending on the causes. Hence, this guide is going to resolve your problem.
Fix#1. Soft Rest Your Hisense Roku TV
A simple fix is to power cycle or soft reset your TV. It removes any software glitch that interferes with the normal functioning of your device. Here is how to do it:
- Turn OFF your TV and unplug its power cord from the electrical source. Also, disconnect the HDMI.
- Hold down the Power button on the TV set for 10-15 minutes.
- Now, connect the power cable back to the power source.
- Switch ON the device and let it initiate.
- Connect the HDMI cable again and choose the correct input source.
Fix#2. Select the Correct Source
Sometimes, the user selects the wrong port. That’s why the cable does not work. There are multiple HDMI ports on your TV labeled as HDMI 1, HDMI2, CEC, ARC, and so on.
If you connect the cable to port 1, choose the source correspondingly. Press the Input or Source button on the TV remote and choose the port in which the cable is plugged.
Connecting the cord to HDMI 1 and choosing HDMI 2 as the source will yield no results.
Fix#3. Switch Between Ports
One cause is that a particular HDMI port is not working on your Hisense TV. Hence, you should connect the external device to a different HDMI port.
Your Roku TV usually has more than one port. Try all the ports one by one. Be sure to choose the correct input source while switching between different HDMIs.
Fix#4. Use A Different Cable
It can be the fault of the cable. First, examine the cable and find any cuts, twists, or bends. In case of serious damage, you should replace the cable.
If the cable is intact but still not working, it can be incompatible. Therefore, you should try a different HDMI cable. If the other one works, the issue is resolved.
Fix#5. Enable the CEC
When you connect your TV to HDMI, CEC should be enabled. This feature is available on most TVs and lets you control connected devices with one remote.
Here are the steps to enable the HDMI CEC on your Roku TV:
- On the remote control, press the “Home” button.
- Go to the “Settings” and then “System”.
- Click the “Control Other Devices/CEC” and hit the OK button.
- Choose one input such as ARC or HDMI 1 and press OK.
- Now, that the CEC is enabled, check the HDMI again.
Fix#6. Check the Source Device
Other than the cable, the issue can also come from the connected device. You may have connected an Xbox, speaker, Roku Stick, or any other device to your TV. Then, make sure the device is turned ON and is working.
Fix#7. Troubleshoot the Connection
A loose connection can also cause this issue that your TV is not detecting anything.
- Disconnect the external device and HDMI cable both from your TV and the device.
- Turn both devices OFF for a few seconds and then ON.
- Now, re-plug the cable and the device.
- Make sure everything is connected properly.
Fix#8. Update Your TV
The no signal issue can also occur if the television has not been updated. It can pose various software issues. Follow these steps to update your Hisense Roku TV:
- First of all, connect your Roku TV to a Wifi network. The internet should have strong signals and reliable connectivity.
- On the remote, click the “Home” button and choose “Settings”.
- Navigate to the “System” and then “System Update”.
- Click the “Check Now” button. If any latest updates are available, the system will show you.
- Install the latest firmware version by following the on-screen instructions.
Fix#9. Inspect the Connection Ports
The connection port either on your TV or the device is defective. Plug the HDMI cable into your TV and check if it fits firmly or wiggles around. Do the same thing with the connected device.
Clean the ports using a toothbrush or clean cloth. Remove any debris or dirt that may be preventing the connection.
Moreover, shine the flashlight in the connection ports and check for any damage or corrosion. You should repair or replace the defective ports to resolve the problem.
Fix#10. Hard Reset Your Hisense TV
A factory reset is another effective solution to resolve the issue. But, you should remember that it will delete all the data and settings on your TV.
Hence, you will need to install the apps and other things again. Consider this fix if nothing else worked. Here is how you reset your Roku television:
- On the remote control, click the “Menu” button.
- Open the “Settings” and then choose the “Support” option.
- Next, click the “Self-Diagnosis” tab.
- Scroll and select the “Reset” option.
- Enter the security PIN if prompted. The default security code is 0000 if you have never changed it.
- Confirm the reset and wait for the process to complete.
