When a My Hisense  goes on and off continually, many things may be at play.

Here are the most common causes:

Faulty Power Supply

Usually, it is the job of the power supply to provide the television with the appropriate voltage. 

If the power supply is defective or has power instability, there are instances when the TV will not be able to hold onto the connection. 

Which will result in too many turning on and off of the TV.

Signs of a faulty power supply

The TV responds to the control input before powering down only to switch on frequently.

Flickering or dim screen.

Odd buzzing or humming sounds from the TV.

Remote Control Issues

Although it sounds funny, a malfunctioning remote control or other electrical appliances may cause the TV’s power cycle to switch on. 

For instance, the remote may be functioning properly but may wind up sending out just ahh unintended signals to the TV.

Signs of remote-related issues

The TV keeps shutting and turning on even when no one uses the remote.

Buttons on the remote feel sticky or are stuck while pressed

Software Glitches or Firmware Issues

Just like any other electronic device recently, Hisense televisions have a software system that operates all features. 

When a device has a flaw in its firmware or there is a new and different update on the system with no bug detection on the latest update.

Strange behaviors such as switching on and off the TV frequently happen.

Signs of software issues

TV shows a complete screen freeze for a while or shows some odd behavior.

The performance of the device is a bad post-firmware upgrade.

It continues to reboot perpetually even when switched off.

Power Surges or Electrical Interference

Problems associated with electrical surges or circuits, and power supply fluctuations.

 Electromagnetic interference from other electrical appliances is the main reason causing your television set to cut out automatically and reboot. 

It may also be due to electrical storms, poor-quality outlets, or overloaded electrical extension cords. 

Game or fence –  Light or elimination screws. Some Examples of electrical issues include but are not limited to:

Signs of electrical issues

Desktop flickering or dims blue screen, right before shutdown.

TV simply turns off by itself mostly when there is a storm or power is cut from an electrical device.

Overheating

Overheating is the most common reason TV turns off by itself.

If the TV gets too hot, it will autofocus CDROM to help cool the components within it.

This excessive heating could result from dust, and lack of sufficient ventilation around the TVs.

Even the power facility games that are and trigger the overheating shutdown.

Signs of overheating

The TV works for a couple of minutes, hours, or even days shuts off permanently, and prevents the usage of the appliance.

Particularly the bottom rear and side area of the TV becomes too hot.

A loud noise of a fan or other devices installed inside the television, and an unusual or odd smell inside the TV set than usual.

Internal Hardware Failure

Due to the hardware problems inside the TV, it can sometimes do some strange actions such as restarts to standby mode.

How to Fix Your Hisense TV Turning On and Off Repeatedly

Now that you know the possible causes, let’s get into the steps of how to troubleshoot and fix the problem. What we have done in this section is offer a breakdown of the 

Step-by-Step Methods To Resolve The Power Supply Issues

Fixing a Faulty Power Supply

To those who suspect that the power supply itself is the source of the problem then these are a few methods that you could try.

 

Step-by-step fix:

Check the power cable:  

Likely, the power cable has not been properly connected either to the wall or to the power supply unit of the TV. 

Where the electric cable appears to be loose or broken, it could be causing overheating instability. 

Try to replace the cable with a new one if it appears old and tattered.

Test a different outlet: 

In current cases where there is no voltage on a plug when the switch is on, the user can connect the plug to any other point on the wall jacks to troubleshoot the problem. 

If you plug it in another outlet that is working and the TV works, that means the first outlet is defective.

Use a surge protector: 

A surge protector guards your television against

power surges and power spikes so find the one that you can afford then connect your television one because if you don’t connect one you might have a damaged television before long.

 

Reset the TV’s power supply:

A simple method to reset the TV is to unplug it from the wall socket for around 5 minutes. Simply plug it in after such a period of time and turn the TV on. 

This method has been known to work because it re-aligns the power supply unit and remedies symptoms that may be of little consequence.

Troubleshooting Remote Control Issues

If one of the problems that causes your Hisense television to switch on and off repeatedly is due to the remote control. 

Here are the troubleshooting tips that you can consider:

Step-by-step fix:

Check the batteries: 

Check your remote and if it does not work, change the batteries anyway. 

Even weak batteries can sometimes create problems and make the appliance behave strangely.

Check for stuck buttons: 

It is also wise to make sure that none of the buttons of the remote are accidentally pressed and are stuck. 

That will signal the television in ways it was not meant to.

Test without the remote: 

Remove the batteries from the remote control and check if the television continues to power on and off on its own. 

If it stops, the problem is probably with the remote control.

Try an alternative remote: 

You may try a different Hisense remote, a universal remote, or any other that you may have to check if the problem is still there. 

The television will work normally with a different remote control however if your original one does not in all likelihood it is the source of the problem.

Addressing Software or Firmware Glitches

Software bugs or firmware issues can also produce a situation where the television keeps going on and off constantly. 

In case, you feel that this may be the reason, you need to do this:

Step-by-step fix:

Update the firmware: 

Go to firmware go to the settings menu and see if a new version has been released for your television set. 

This is usually due to the fact that most of these firmware updates are intended to fix bugs that may affect the televisions working poorly.

Reset the TV to factory settings: 

If updating the firmware did not work, Try factory resetting the device. 

This will remove all the custom settings made, but it may correct faults due to software incompatibility or corruption.

1. Use your remote and press the “Settings” button.

Some power strips can handle limited power pipes which are low when televisions and radios are plugged in resulting in breakdowns.

Unplug other devices:  

Unplug any unnecessary devices from the same power outlet or power strip that the television is connected to. 

This will help prevent the television from any electrical interference.

Install a surge protector:  A surge protector can protect from soaring currents due to stormy weather or a faulty electric wire. 

Ensure that it has a good joule rating the greater the rating the more efficient the protection.

Dealing with Overheating

Overheating requires a cool-down period such that an overworked person will do something such as shutting the machine off ideal for internal parts likely to suffer damage.

Step-by-step fix:

Improve ventilation:  

Maintain enough circulation of air around the television set. Avoid placing the TV in a confined area or even directly in front of the VCR.

Clean the vents: 

The presence of dust dirt or whatever is sucked up through the element will restrict airflow and will lead to overheating of the television. 

Using the Appropriate Cleaning Method for the Thermal Ventilation System. 

Using a soft brush or compressed air, clean the vents carefully and delicately.

 

Place the TV on a flat, open surface: 

Try not to keep the TV on soft surfaces such as a cushion as this will block airflow. It is better to put it on a hard and even surface.

Addressing Internal Hardware Issues

If none of the above solutions helps in solving the problem, it could be somehow associated with hardware failure. 

Sadly, this is a bit more complicated in terms of solving it yourself, and so you will probably have to seek help from specialists.

Step-by-step fix:

Check for visible damage: 

Look for cracks on the back of the TV and blows on the boards (opened as they are if at all). 

A circuit board for discharge or damage like burn stain areas, swollen joints on capacitors, and offensive other cable wires.

Contact Hisense support:  

if the TV is under warranty you should contact Hisense customer support or take the TV to an authorized service center for repair. 

In this case, the customer should be made aware that it is best to get the internal components replaced by quality hardware specialists.
