Try the next solution if your Hisense Roku TV is still not turning on.
Check Power Supplies:
Ensure all your power supplies are working. If the voltage of your household has gone down, your TV might not be getting the wattage it requires to turn on. It could also be a fuse issue. Check the other appliances in your house that require a high amount of power and verify whether they are working fine or not. If they are also behaving abnormally, the problem is with the power supply. You need to call home an electrician and check everything in your house.
You can also call the local authorities responsible for providing electricity and ask whether there is an issue with the current supply.
If everything is working well regarding power supply, but you are still witnessing the issue, try the next solution.
Check the Wall Switch:
Over time, the contacts in a wall switch might get dusty or rusted. Again, the plastic or metal parts inside the wall switch may become loose and allow it to move around. This can prevent the power socket from connecting well with the contact points on your Haier TV’s power cable. To fix this, you need first to check your switch. Firstly, remove the faceplate from the wall switch. Then clean any debris or dust you see using a cloth. You need to turn off the power supply before trying all of it, as a simple mistake can get you electrocuted. After cleaning and tightening everything inside the wall switch, put the faceplate back and turn the power on.
If your TV is still not turning on, try the next solution.
Inspect The Display Cables:
The cable you are using to connect your TV to your set-top box must be working. Ensure the cable fits well at both ends with no gap between the port and the cable. Even the smallest gap can cause the TV not to turn on.
You also need to check the cable for any visible damage. If there is any tear in the cable or any part of it looks burnt, you need to change it. You can find such a cable in any electrical store near your house.
You have your solution if the TV turns on after changing the display cable. The display cable was indeed the culprit. But try the next solution if the TV does not turn on even after changing the cable.
Test the power cord:
Take out the power cord connecting the TV and the power socket. Now plug that cable into another TV or monitor. If it works well with the other devices, move on to the final solution. But you have your answer if it does not work with the other device. The power cable is the culprit. You can find a new power cable in any electrical store near your house. Trying out the new cable should solve the problem for you.
Disconnect All Connected Devices:
If you have several input devices connected to your TV, like a USB device or any console, try removing all of them. Remove all the items you might have had connected to your TV, and then turn off your TV entirely. After that, with all the accessories or devices disconnected, turn on the TV again.
Try the next solution if it still does not turn on.
Hisense Roku TV’s come with a physical hard reset button next to the HDMI ports. You can try using it to see whether that solves your power supply problem. You will need a matchstick, toothpick or safety pin to press the tiny button though.
Let’s take a look at the steps for it then.
- Locate the reset button next to the HDMI ports. You should see a name or marking saying “reset” next to a small button. And that is the reset button you are looking for.
- Once you locate it, press and hold it.
- The TV will initiate the hard reset process on its own.
- Once it turns on again, you will see the Hisense logo. You are required to press and hold the reset button till you actually see the Hisense logo on your screen.
If this does not work on your Hisense Roku TV as well, move on to the next solution.
Hisense Roku TV Turns On But Black Screen:
If your TV turns on, that is you see a blinking LED, but you only see a black screen even when you use a working remote, it could be a motherboard or backlight failure. You can fix this on your own, but you will need some repairing skills and replacement parts to do the job efficiently.
Usually, the backlight does not fail on a TV. In reality, the power board fails most of the time, resulting in the backlight not receiving the required power to turn on.

And to check that, follow the instructions mentioned below.
- Turn on your TV.
