How to Fix Hisense Roku TV Won’t Turn On
It’s possible to encounter a sudden power issue on your Hisense TV. Regardless of its model, you can try the following fixes below. Remember to go over them one by one to see which works best for your Hisense TV.
Fix #1: Power Cycle your Hisense TV
Power cycling is a quick solution for most glitches in smart TVs. This resets all the TV’s internal components to their stable state. It’s a harmless fix and doesn’t delete your smart TV’s saved data.
To power cycle your Hisense TV, follow these steps:
- Unplug the power cable of your Hisense TV from the socket and wait for thirty minutes. During this step, also press and hold the power button on your TV for ten seconds to help drain more power.
- Then, plug it back into the socket and try turning it on. Check if the issue is solved.
Additionally, you can check your TV’s power cable for damage. A tear on its cable or a slight play on its pins can cause the TV to be inoperative. If this is the case, try replacing the power cable and see if this solves the issue.
Fix #2: Try Other Wall Outlets
If you’re using an old wall outlet for the power cord of your Hisense TV, chances are there are problems with the current outlet. Loose connections inside outlets provide inconsistent power supply and can sometimes damage your TV. Your TV’s indicator light should show a red color once it receives power before turning on.
To confirm if this is the case, try plugging in another device—like a phone charger—and see if it charges your phone consistently. If it works, the problem may come from your smart TV.
However, if the socket doesn’t work, try using other ones in your room. Also, avoid using power strips and surge protectors as they can sometimes provide inadequate power for your Hisense TV, especially when there are other devices connected to it.
Fix #3: Disconnect All Connected Devices
Some input devices can put your TV to Standby Mode once they’re not properly connected or malfunctioning. This can prompt your device to show a black screen but has audio. To solve this, disconnect all connected devices first, then check if they’re in good condition.
Check the cables that they’re connected to (HDMI, VGA, USB-C, etc.) and replace them if you see any damage. Also, see if the ports are not damaged or corroded. When the current one doesn’t work, try using the other ports and see if this solves the issue. If you are unsure what to do, we have an article on how to change input on your Roku TV.
Fix #4: Check the Remote of your Hisense TV
Once your Hisense TV receives power but does not turn on, the issue may be on its remote. Try replacing its batteries first and check if your Hisense TV turns on. If it’s still unresponsive, replace the remote with a working one and try turning on your TV. Also, avoid interferences that might be causing the TV remote to have signal problems.
Fix #5: Do the Flashlight Test
The flashlight test is a quick way to diagnose if your smart TV has problems with its LED backlight. This is a common problem among many Hisense TV models and can cause a black screen on your TV’s display.
To do the flashlight test on your Hisense TV, proceed to these steps:
- With your Hisense TV turned on, switch on your flashlight and point it to the TV screen at a close distance.
- Look for unclear images on the screen. If you see a blurry word or image, the LED backlight system of your Hisense TV might be damaged.
When this happens, try consulting Hisense Support to get the LED backlights replaced.
