Hisense TV Blinking On and Off – Probable Reasons With Solutions

• TV Connection Errors
• Heat Issues
• Power Fluctuations
• Options Corrupted on Hisense TV
• Unsupported Refresh Rate on Hisense TV
• Problems Due to External Connection
• Technical Issues in Hisense TV
• Hardware Defects of Hisense TV

The above factors could have caused your Hisense TV to blink on and off. I have mentioned the appropriate troubleshooting methods in the upcoming heading.

TV Connection Errors

Before assuming that serious problems have arisen when the Hisense TV blinks on and off, you should first check whether the connection is made properly. This mainly applies to users who bought the new Hisense TV just a few months ago. While checking the connection, glance at the TV cords as well. Because if they are damaged, you could expect these types of issues.

Solution

Go near the power socket to which you have connected your Hisense TV. Look whether the TV power cord is tightly attached to the socket. If it is loose, insert it into the cord firmly and ensure a strong connection. Suppose the power cord does not fit into the power socket and falls out after some time, you have to use a junction box and plug it into the power socket. Then, connect your TV cord to the socket on the junction box and continue watching the TV without it blinking on and off after making a connection in this manner.

If the connection is fine, you should check if the power cord of your Hisense TV is impaired. If the wire is bent, straighten it, and it may work. Look for crushing, insulation damage, or core rupture. Also, shake the pins on your power cord and make sure they are not broken. If you find any such things, then repair the wire or replace it completely.

Heat Issues

Suppose the connection and cord condition are good; touch your Hisense TV unit and observe. If you can feel the heat, then your TV has been overrun. You might have been binge-watching the whole night or left it running even if you were not watching it. Due to this, your Hisense TV is heated up, and that’s why it blinks on and off.

Solution

A simple way to save your heated-up Hisense TV is by resting it. So, first, turn off your Hisense TV. Then, turn to the backside of your TV and remove the power cord connected to the power outlet. Leave it idle for about 15 to 20 minutes and cool it down. After this power cycling, make the connection again. Press the Power button and turn on your Hisense TV. Access it for some time, and you can see your TV running normally without blinking on and off. If the same issue prevails, then move on to the next troubleshooting method.

Power Fluctuations

The normalcy of power supply in the ambiance of your Hisense TV is very much inevitable for it to function efficiently like it always does. Suppose it is inconsistent, then naturally, your TV will be on and off. Moreover, this problem might occur even when sufficient voltage is not delivered to your Hisense TV. This scenario is something serious to look at.

Solution

See whether your home is receiving a constant current supply. If not, then there’s nothing else making your Hisense TV blink on and off. You have to wait until the power distribution becomes stable to enjoy complete accessibility of your TV.

Suppose the power supply is normal and the other devices are working well, and turn your attention to the power outlet of your TV. Check whether its prongs are blocked by dust or debris and clean them immediately. Using a tester, check whether all the slots have a power supply. In case any slot is not delivering power or if the power outlet is damaged, bring home an electrician and repair it. Until then, you can connect to any other power outlet and use it.

Suppose your Hisense TV is not working on any power outlets in your home; then it is sure that it doesn’t have a sufficient voltage supply. You should immediately stop using the TV if this is the case. If you continue to use your Hisense TV despite low or high-voltage power, then it will cause permanent damage. With an electrician’s support, stabilize the voltage supply and think about using your Hisense TV after that.

Options Corrupted on Hisense TV

Various features, like an energy saver & sleep timer on Hisense TV, allow to control viewing time and reduce unnecessary power consumption. However, these options are optional and become active only after you enable them. They might possibly get corrupted due to bugs if you have enabled any of them and make your Hisense TV go off and come back again.

Even if you haven’t turned on these features, they themselves start functioning because of glitches that bring up such types of issues, especially after updating your Hisense TV firmware.

Solution

Though it will be tough to access your Hisense TV in this situation, manage to reach the Settings option on your Hisense TV before it goes off. Check whether the Sleep timer is ON. If yes, disable it immediately, and you’ll be out of the issue. In case it is already off, hover through the respective options and turn off the energy saver on Hisense TV. When you don’t have the previously mentioned scenarios and also have turned off these power consumption functionalities, you will not have a Hisense TV blinking on and off issue henceforth.

Unsupported Refresh Rate on Hisense TV

This is a rare yet possible factor. You might be trying to play media content with a refresh rate that is currently not set on your Hisense TV or unsupported by it. Unable to cope with that, your Hisense TV flickers on and off. This issue generally relates to old models of Hisense TVs and not often to the latest ones.

Solution

To bring a solution to this issue in one move, you can reset your Hisense TV Picture Settings. The procedure to do so differs for each Hisense TV model, and the following table will showcase that.

TV Model	Procedure to Reset Picture Settings
Hisense VIDAA TV	Settings → Picture → Restore Default Picture Settings
Hisense XClass TV	Settings → Picture and Sound → Reset picture and sound settings
Hisense Roku TV	Settings → System → About → Advanced System Settings → Factory Reset →  Reset TV audio/picture settings. Then, click the Play/Pause button on the remote 3 times.
Hisense Android TV	Settings → Device Preferences → Picture → Reset to default
Hisense Google TV	Settings → Display & Sound → Picture → Reset picture style

If resetting picture settings didn’t fetch you a favorable outcome, then ignore accessing that particular media content on Hisense TV.

Problems Due to External Connection

Sometimes, the actual problem will not be in your Hisense TV. You might be accessing streaming devices like a streaming stick, streaming box, or DVD player by connecting them to Hisense TV. If something is not right about it, for example, if there is a loose contact, then your Hisense TV will close the device’s interface and bring it up again due to its improper connection. Upon seeing it, it will look like your Hisense TV is blinking on and off, but it is actually not.

Solution

Do all the inspections you did for your Hisense TV to the external device from the start, like checking the connection, determining their normalcy, damage on wires, etc., and take the necessary actions to resolve issues, if any. Mainly check whether a particular port to which the streaming device is connected is problematic and switch to an alternate input source on Hisense TV. If you are using DVD players that don’t use the HDMI connection, repair its respective port on Hisense TV to avail of its accession.

Technical Issues in Hisense TV

If you have reached this stage after trying all the above practices to troubleshoot your Hisense TV, then I could sense some technical error on your device. It should be terribly affected by corrupted cache, bugs, or even virus attacks. You have to consider now and eradicate them immediately to stop your Hisense TV from blinking on & off and to refrain from getting into some other problems.

Solution

Somehow, go to the Apps Settings and clear the cache files on your Hisense TV. Because cache deleting will potentially clear up all the problematic agents. Perform a restart and see if the problem is solved.

If it is the same, then see whether your Hisense TV firmware is up-to-date. If not, update it at once. Suppose the problem has arisen after you updated the software, then factory resetting your Hisense TV brings it back to its condition when you bought it.

Resetting would have wiped out everything that is troubling the functioning, and you can set up your Hisense TV and start accessing it without it blinking on and off.

If all these efforts are in vain, scroll down to the next heading and make your next move.

Hardware Defects of Hisense TV

If all the above troubleshooting methods fail to fix your Hisense TV’s blinking on and off issue, then some important hardware parts are damaged. If it is an old model, your Hisense TV backlight is not working. Otherwise, the motherboard is having an issue. You can’t do anything about these hardware defects.

Solution

Contact the Hisense TV customer support [Phone number: +1 (888) 935-8880, Email address: [email protected]] or a nearby service center and report the issue. They’ll send assistance and take the TV for repair. If the backlight is damaged, you are slightly lucky, and you have to spend around  $100 – $250 to repair it. Suppose the motherboard is damaged, then the repair cost will be high. Sometimes, you will have to replace them completely. So, better claim the warranty for your Hisense TV and get the replacement or service for a lost cost or free of charge. After repair, your Hisense TV will definitely be out of any sort of issue.

Tips for Prevention
