For home entertainment fans, a Hisense Roku TV is something worth mentioning on social media, something worth writing home about. The Hisense brand is well-known for making display panels for other, more expensive brands.
Therefore, with a Hisense TV, you are essentially getting a similar quality panel without the price hike of a more established brand.
In addition, the Roku is an excellent smart TV platform with many features and functionalities you will not find in more basic solutions like the built-in “smart TVs” that come with most televisions manufactured between 2015-2018.
A Hisense Roku TV stands at that sweet spot between price and performance.
With that said, your experience might be interrupted when you run into certain issues. Many users report their Hisense Roku TV units failing to turn on.
With this guide, you will know the probable causes behind this and the steps that you can take to solve the issue before having to turn to support and repair scenarios. We will explore the common culprits behind this problem and provide you with an easy-to-follow guide that includes simple diagnostics and fixes you can do yourself at home.
Read on to find out more about sorting out the issue of your Hisense Roku TV not turning on.
The most obvious reason why your Hisense Roku TV is not turning on would be a faulty power cord. The power cord connects your TV to the wall outlet and will not supply power to your TV if a malfunction occurs.
Forgive us if any of this seems obvious — we want to start with the simple fixes and work our way from there.
Check the power cord carefully for any fraying or tearing. If you see the sheathing broken or exposed wires, discard the power cord immediately. If you have a spare power cord, use that to plug in the TV and see if the issue is resolved.
Thankfully, the power cord is pretty standard on most TVs, so you might be able to find another one in your junk drawer!
Another obvious issue might be a malfunctioning wall outlet.
Fortunately, this is very easy to check. You can plug another appliance into the wall outlet and check to see if that works. Alternatively, plug your Hisense Roku TV into a different wall outlet and see if it works.
If another wall outlet solves the problem, then the issue has already been diagnosed. However, if your power outlet is functioning properly but your TV still will not turn on, follow the next steps of the guide to check out other possibilities.
The next logical step is to power cycle or reset your TV. In many cases, this is enough to solve the problem and bring it back to life.
To do this, unplug your TV from the outlet, wait for a couple of minutes, and plug it back in. Try to see if the TV turns on.
If it behaves the same, turn it off and unplug the power cable. Give the TV another few minutes, during which time you should press and hold the power button located on the body of the TV to make sure that any residual power is properly drained (this will be either on the back of the TV, or on the bottom in the center).
Then, plug the TV back again and see if the problem is gone.
Now it is time to check your TV for any kind of connected devices. Certain devices can force your TV to go into standby mode and this is something you need to eliminate as the next diagnostic step.
Check the rear connection ports of your TV to see if anything is connected. This can include USB devices, HDMI cables, and analog video cables.
Unplug everything from your TV and then power cycle the unit. Give it a couple of minutes, and then try to restart the TV. If one of those devices was the culprit, the TV should not start normally.
Take care to also remove network cables from your Hisense Roku TV if you have any connected to the integrated ethernet port.
Check Your TV Remote
*Again, this might seem obvious. Hopefully you have already attempted to turn on the TV via the physical button on the device, rather than just using the power button on the remote. If not, put down your remote and try to turn on the TV itself.
If all the above steps fail, then there is a high likelihood that your Hisense Roku TV remote is not able to communicate properly with the TV. This can definitely cause issues as a faulty remote will not let you bring the TV out of standby mode, thereby giving the impression of it not turning on.
First, you should try using your remote to turn on the TV from close proximity, taking care to avoid any kind of object or obstacle between the remote and the TV. If this does not work, replace the batteries of your Hisense Roku TV remote with fresh ones and try again.
As a last resort, you can try using a replacement remote for your Roku TV if you have one at hand. If your remote is completely non-functional, a replacement will solve the issue immediately.
Reset Your Remote
Sometimes the remote malfunctions even when it has charged batteries. In this case, you will want to reset your remote.
To reset the remote, simply remove the batteries, hold the power button (on the remote) for 20 seconds, and then re-insert the batteries. Now, hit the power button and see if the TV comes on.
Now, we have to move on to more serious potential issues and fixes. The backlight provides illumination to the TV screen and is responsible for emitting the light that viewers see originating from the TV. A failed backlight will keep the screen dark while the other functionality of your TV will still be working fine.
A tell-tale sign of this is a dark TV screen while the power light of the TV is still on and you can even hear audio from the TV. If this happens, do the flashlight test. For this, you need a powerful flashlight, preferably one that can concentrate the light within a small area.
Turn the flashlight on and focus on the TV screen from a couple of inches away. If you can see soft, blurred images on the TV when the light is focused, you definitely have a backlight issue. Unfortunately, LED backlight repair or replacement is a major task that is best left to the professionals.
Get in touch with Hisense support and describe the issue so that the company can arrange to have your TV repaired.
If the issue of your Hisense Roku TV not turning on has not been resolved yet, you might want to consider performing a hard reset. Stemming from this, remember that this is a major step with consequences.
A hard reset will automatically wipe the memory of the Roku system integrated into your TV and bring it back to the factory state. As a result, all of your apps and data will be wiped away and you will have to manually install and configure them one at a time later. (But no, you cannot wipe away these high food costs and you cannot wipe away the fact that you ever saw The Force Awakens).
If you decide to do a hard reset, you need to consult the manual for your Hisense Roku TV. Look for the location of the small hole that holds the reset button. Once you locate it, bend one end of a paper clip and insert it into the opening. Force it in until you hear a click and hold it in for 20-30 seconds.
Once the reset is done, your TV should power cycle on its own and start booting up. If this does not happen, you can also power cycle your TV manually using the steps already outlined and see if the problem is taken care of.
*Lastly, if your TV is app-compatible, you will likely be able to factory reset the TV via prompts on the app.
At this point, if everything you have tried has failed and your Hisense Roku TV is still not turning on, you might be looking at a major issue. It is highly likely that you would have to send your TV in for repairs.
Taking this into account, you can still try to diagnose the issue with your TV by looking at the power LED. In Hisense Roku TVs, the power LEDs are supposed to provide visual codes if there is an internal problem and you can interpret these codes to diagnose the issue.
The best possible situation would be if you see your power LED flashing red in a consistent pattern. This is indicative of a problem with the power board. While it will need to be replaced, it is a relatively inexpensive part and you can have the peace of mind knowing that the main important components of your TV are probably fine.
Moreover, if the power LED glows a constant red, even when you are pressing the power button on the body of the TV, the issue is most likely with the motherboard. That is a major repair that will take time and be expensive if your TV is out of warranty. Not something many people want to hear in these inflationary times.
On the other hand, if the power LED is not glowing at all, even after you have supplied power to the TV, the issue might simply be a blown fuse. The fuse is very easy to replace and you might even get away with a home visit from a repair technician.
Contact Hisense support, describe your problem, and have your warranty documents close by if your TV is under warranty.
DIY Option: Replace the Power Board, Main Board and/or LED Strips
Since not everybody is looking to disassemble their TV, we won’t get too far in the weeds here.
But if you are still reading, it is quite likely that the power board on your TV has gone bad. Generally, this part is available for less than a hundred bucks, but be sure to verify the compatibility with your exact TV model.
This fix isn’t especially challenging, but it requires a proper diagnosis and accessing your TV’s internal components. So proceed with caution, and be realistic about your level of DIY skills.
With these easy steps, you are much more likely to find the root cause behind the problem and sort out the issue of your Hisense Roku TV not turning on yourself at home.
Of course, if none of the above methods pan out, you always have the option of contacting Hisense support and requesting a repair. Based on this, if your TV starts working again after trying one of these fixes, you can go back to consuming entertainment in peace without all the hassle.
