Hisense television is known for its high-quality, budget offerings TVs, which is why they are so popular and widely bought by consumers. But having a Hisense Roku TV that won’t turn on can be a frustrating problem that can ruin your mood.
Many people experience problems with their Hisense TV and the issues might seem unfixable at first, but you just need to check out a few things to better troubleshoot the issue.
But what is causing the issue, and how can we fix it?
Hisense TV won’t turn on
If your Hisense TV won’t turn on try this simple solution first. Unplug it from the wall outlet, wait for 60 seconds, then plug it back in and turn it on. If this doesn’t work try another outlet, or check that the power cable is properly inserted in the back of the TV.
If this doesn’t work it might be related to other hardware problems so you will need to further investigate the issue.
Check the wall outlet power supply
If Hisense Roku tv wont turn on maybe the issue is not with the TV itself, but with a faulty power outlet.
When the power outlet is not working properly it will not provide enough power for your TV to function properly, so the TV might turn on and off without an apparent reason.
If your Hisense smart tv is turning off repeatedly this can be caused by a loose connection to the power supply.
You can unplug the power cord from the power supply, and then plug it back in to make sure the connection is not loose and the Hisense TV is receiving power.
If you suspect the power source is faulty you can check it with another device to see if that functions properly.
If you have issues with the second device as well then you know the issue is not with your Hisense TV, but with the power source.
While you’re testing power supply sources you should also try to plug in your Hisense tv to a different outlet to see if that makes a difference.
In this case, you should contact an electrician to have your home power network checked out.
Check if the power cable is faulty
A faulty power cord can make your Hisense TV not receive enough power to turn on, or not receive power at all.
The Hisense TV red light might turn on or not show at all, depending on how much power your TV is receiving.
There are a few easy ways of telling if the power cable is faulty. The first way is to check the entire length of the power cord for any visible damage, like exposed wiring, visible cuts, or missing insulation.
If your cable shows visible signs of damage you should replace it with another one and see if your Hisense tv turns on after that.
After you replace the cable check if the red light turns on or not. If the red power light is still not turned on, it might mean that the issue is with another TV component.
Check if Hisense smart tv is in standby mode
Some Hisense TVs will go on standby if no input source is selected. This is triggered by a TV function, and it happens when a set-top box or streaming box is not properly connected to it.
To check if this issue is caused by an input source you should cycle between multiple sources on your Hisense tv to see if others work.
Then, you should plug other devices into the same cord, like a Blu-Ray player, to see if the issue is with the source or with the cable.
You should try different HDMI ports, or remove any HDMI cable extensions to see if you have any issues with the current port you’ve been using.
If none of these ports work you should switch between VGA, HDMI, and RCA to see if the issue is present with all the connected devices.
Check your Hisense tv remote
If your Hisense TV is showing a red light on the front of the TV, but you’re pressing buttons on the remote control and nothing happens then the issue might not be with the TV, but a faulty remote control.
If you have another TV remote you can try it and see if you can turn on the TV.
Make sure to remove any objects that could be blocking the signal transmission between the remote control and the Hisense tv.
While you’re verifying the remote control you can try it on another Hisense tv and see if works for it. If it works then the issue is with your TV.
Also, make sure you check if the batteries have enough power and are placed correctly in the remote. You can remove the batteries, wait for a few seconds and then put them back in.
You might not consider this when you’re worried about the Hisense tv not working, but even your remote can cause these apparent serious issues.
Reset your TV
Your Hisense smart tv can suffer from configuration issues that are preventing it from powering on properly.
Any changes you made in the settings can cause the device to behave strangely, such as not turning on or having a black screen.
In this case, it is necessary to remove all configuration files and return the device to default settings.
To eliminate these issues you will have to do a factory reset which will return the TV to factory mode.
To perform a factory reset the first step is to remove all devices and the power cord from the TV.
Then, you should keep the power button pressed for 30 seconds, and then release it.
Wait for 2o to 30 minutes before you plug the TV back in, to make sure all the residual power is drained from it.
After the 30 minutes have passed you can plug the TV back in and see if the red light is turned on. You can try to turn on the Hisense tv after that.
You can also do a factory reset by pressing the reset button on the back of the TV. The reset button is a small button that needs to be pressed with a paper clip.
Simply locate the reset button, apply mild pressure and keep it pressed with the paper clip for approximately 15 seconds and the TV will restart.
LED backlights failure
A common issue with TVs is the failure of the LED backlights. When this happens your TV will turn on and you will be able to hear sounds, but you will see a blank screen.
This is usually caused by a fault in the power board circuitry or the circuit board inside your TV.
To check if the power boards are the issue you should follow these steps:
- Point a flashlight on the TV at close range
- Check to see if you can observe any text or images on your TV
- You will want to make sure brightness settings are properly set
If you’re able to see anything on the screen when you point a light source at it from close range then it means your LED backlights are broken.
If that’s the case you should contact a local TV repair store to have it checked out.
Unplug all network devices
If you have a flashing red light or blue light on your Hisense tv, or a flickering screen this might be caused by an internet connection issue, a bad connection to the modem or router, or a motherboard issue.
If this is happening with your Hisense Roku you will want to remove all Bluetooth and network connections from the device, unplug it, and then connect all the devices or cables back to it. Your TV should not have any other external interference from other devices or streaming sticks.
Make sure everything is connected properly before you turn the device back on.
Common Hardware problems
If none of the above solutions work then you might have further hardware problems with your Hisense tv.
Here are the most common issues happening with a Hisense Roku tv:
- If Hisense TVs are flashing red then the most likely issue is the power board. This can be solved with a power board replacement, and it’s usually an inexpensive fix
- If the power button remains red without blinking when you press it then the most likely issue is with the main and power boards
- If you unplugged your TV and it won’t turn back on then you probably blew a main fuse, which will need replacement
- If the screen is flickering, the picture disappears after a few seconds, or the TV will not turn at all then the issue might be caused by a bad capacitor on the circuit board
Conclusion
While most software issues are easy to fix at home if you have a hardware problem you will probably need to contact a local repair shop.
Fortunately, most problems are not really expensive and should be fixed quickly by a professional.
Before taking to a repair man try the fixes suggested in the steps above and see if any help your situation.
If the issue is with the tv not turning on you can try to power cycle it, change the power adapter, try a different power source or change the TV’s power cable.
If you’re using a power supply adapter you should remove that and connect the TV directly to a different wall outlet.
You also need to make sure you have proper power flowing through the electronic device and the wall plug is not defective.
Hisense TV not turning on is a rather common problem, but there are easy fixes that can help get your smart tv back to work.
