Fix: Hisense TV HDMI not working (Roku TV)
Method 1: Check if input device is working fine
The first and foremost step when your input device (like Roku TV) is not working should be to check the power light on the device. Check if your device is receiving power and is working fine.
If the power light is not on, then there is some problem with your input device. Check if it’s receiving enough power from the supply outlet. Try changing its supply outlet. Or get your device checked once.
Method 2: Re-plug the input device
Sometimes unplugging the input device and plugging can get the signal back. If you are using a Roku TV device, you can perform a reboot to fix this issue.
Unplug the device from the power source, unplug the cables, and leave it undisturbed for a few seconds. Now plug it back in and see if it is working. Remember to plug it back in carefully and to the correct input ports.
This method might have fixed any minor issues, but if the issue pertains, we will suggest you proceed with the next step.
Method 3: Check the input source connection
Now that you have checked that your input device is working as intended, it is time to check if your Hisense TV is receiving the input source signal.
There are a few things that you need to check.
First, check if you have connected cables to the correct port on your input device and the output device (TV).
You can check the input source of your TV by pressing the input or source button on your remote. If you don’t have a direct button, then open settings and find the input source.
Make sure to choose the HDMI port correctly. You can also switch the HDMI port and check.
Secondly, check if the HDMI ports on your Hisense TV and the input device (Roku TV) are working fine.
You generally have multiple ports on your TV, and you can try checking the different ports.
Method 4: Try a different HDMI cable
Firstly, check if the cables are firmly connected to your television set. Even if HDMI ports on both devices are working fine as intended, you might see issues with your HDMI signal if you are using a faulty HDMI cable.
Always use a high-quality HDMI cable. Sometimes, poor-quality cables can invite interference issues as well. And poor quality cable wears out quickly if you perform multiple plug-unplug cycles or bend it a lot to pack-unpack.
Method 5: Contact Hisense TV Support
