Personal Anecdote: The Irksome Turn Off And Power Back Of The TV

Samsung TV Flashing On And Off

Several weeks back, I was in a troubling situation like that. 

There was a new series on Netflix that I wanted to watch and after grabbing some snacks and drinks, I sat down ready to watch the series. Immediately the TV turned off. 

As I was trying to look over the problem, it turned back on, but only for five seconds before it turned off completely. 

I guess I was subjected to this cycle for some time until I had to quit and sleep feeling a bit angry.

Well, I expected that the television was damaged. It wasn’t that long ago that I was in a state of incredulity when the gadget simply shut down repeatedly. 

It turns out however that the television was not broken and that some options could be explored after some probing the next morning.

If you have been facing the same issue, however, you need not worry. There is a good chance that your TV can be repaired in a few simple steps. 

First, let us examine the problem and its possible causes a little more closely.

Why Does My TV Keep Turning Off Every 5 Seconds?

There are times when the sound of the incredible craftsmanship of a plasma screen television is not fully enjoyed by users because the device has a self-shutdown every 5 seconds.

It is good that there is an easy way out of this kind of problem, but first, it helps to understand the different possibilities as to why this issue occurs.

Power Supply Problems

One of the most common causes of saturation in hearing, once you begin to calm yourself down after living with your TV for a while, is a major fluctuation or total interruption in the power supply. 

There is simply no reason for a TV to turn off on its own although such instances do occur. 

On such occasions, the television set usually comes with components that automatically detect the problem because it has the potential to be damaging to the set itself. 

Depending on whether the cord or plug connection is faulty, an improper connection to a power source may lead to disturbances. 

This automatically disrupts the practical aspect of the television where technical systems come into play which turns the device off and on whenever there is a disturbance. 

If the cord was manipulated during maintenance work, there is a chance of a faulty slip where the power would not reach its outlet which again causes the television to switch off automatically. 

Faulty Power Cord or Plug: 

The same can be said about power plugs, broken circuits, and short circuits. 

Any instance of defective cords or plugs is likely to lead to the need to switch the power cable or the plug comes into effect.

Electrical Surges or Fluctuations: 

Power surges, however, are usually out of the ordinary as these disturbances usually occur outside of a cable’s power supply when a thunderstorm strikes .

There is a shortage of power caused due to faulty wiring. 

Whenever such disturbances occur, several components of the television turn off automatically.

Faulty Power Supply Board: 

The power supply board incorporated within the TV is quite crucial as it regulates the power inputted being distributed to all parts of the TV. 

However, whenever the power supply board is not functioning, the TV may turn off at odd intervals.

Overheating

If your TV becomes excessively hot, it will turn itself off for self-protection. 

The overheating can be caused by:

Poor Ventilation:  

The positioning of your TV in confined places with little ventilation can cause overheating of the unit. In this regard, 

It is advisable to position your TV in a location where adequate space is available which will allow heat to escape.

Dust Accumulation:  

Inside the TV set, there is dust and debris which in most cases accumulate and obstruct ventilation gaps of the TV set leading to too much heat in the internal parts of the TV which in most cases are not visible.

Internal Component Failure:  

Internal parts that have failed such as the fan or the heat sink which are the components responsible for heat elimination can also be the reason as to why the TV overheats leading to self shutting down.

External Device Interference

Sometimes other connected devices to the TV can also be responsible for causing the device to shut down. These can be

HDMI Devices: 

If there is a DVD player game console or sound bars that use the HDMI ports to connect to the TV set. 

Then it is most likely the HDMI cable that is causing the problem due to inconsistency or some defect.

Streaming Devices: 

Apart from the mentioned devices, other inputs such as the Roku, Amazon Fire stick, or Apple TV can cause the TV to function improperly when there is a problem with the device or its settings.

Cable Box or Satellite Receiver: 

The use of an external satellite box or satellite receivers has been reported to contain a malfunctioning device causing the TV set to go off due to poor signal quality.

Settings Issues

Flicking off the main switch of your television may not be the only reason why your television seems to turn off. 

Indeed, any television has a built-in timer and energy-saving functions. However, sometimes these functions may prove to be more of a nuisance than an advantage:

Sleep Timer: 

A number of modern televisions come fitted with a built-in sleep timer that automatically powers down the TV after a specified period. Ensure that you are not using this feature.

Auto Power Off:  

In some television models, there is a function that halts output when no signal has been received for a given duration. Verify whether the function is present and active.

Firmware or Software Issues

This can arise also out of glitches, bugs, or outdated firmware. 

Throughout the lifecycle of the TV, the manufacturer is expected to release various updates that will provide any necessary bug fixes as well as upgrades to the performance levels. 

A TV that has had all the necessary updates may be more robust to problems involving overheating and randomly switching off.

How to Fix the TV That Keeps Turning Off Every 5 Seconds

Having discussed possible reasons for the issue, it is time to address solutions. The solution will vary depending on the root cause of the problem. 

Here are a few troubleshooting steps that can help you identify and fix the issue if necessary.

Step 1: Check the Power Supply

Solution: 

If the power supply settled is found to be the problem, then the following steps can be followed:

Inspect the Power Cord: 

Conduct a visual inspection of the power cord to verify whether any parts of the cord are hanging out of place. If it’s kinked, torn, or loose, it will require changing.

Try a Different Outlet:

 Attempt to plug your TV into a second outlet to confirm that the problem does not exist with the outlet itself.

Use a Surge Protector: 

If your TV does not use a surge protector, perhaps it will be a good idea to plug it to one. This might extend the lifespan of your TV in the event of sudden electrical fluctuations.

Check for Electrical Issues:  

In the event that the problem still exists, it may be related to some electrical problems within the house. You may require the attention of an electrician to see the configured wiring.

Step 2: Prevent Overheating

Solution: 

If overheating is the source of shutdowns, follow these steps:

Ensure Proper Ventilation: 

Place the TV in an area that is not entirely closed and allow there to be some space immediately surrounding the unit so as to allow enough air to circulate into the unit.

Clean the Dust: 

Using either a soft cloth or compressed air, clean the dust off the TV’s exterior and vents and where dust has built up on the TV’s internal components (if any are free to you).

Use a Cooling Fan: 

To keep the air temperature in a TV room on the lower side, use a cool fan or move the TV unit to an area that does not receive a lot of warm air.

Step 3: Disconnect External Devices

Solution: 

In the case of external devices causing interference, do the following:

Disconnect All HDMI Devices:  

Remove all the HDMI devices (game consoles, DVD players, or soundbars) connected to your television, and check to see if the problem persists.

Test With One Device: 

Try connecting each device one by one to see whether a specific device is causing the problem.

Update or Replace Cables: 

Check the quality of HDMI cables as well as their compatibility with the flat screen.

Step 4: Adjust Settings

Solution: 

If your TV does turn off on its own, over an adjustment or feature, follow these instructions:

Disable Sleep Timer: 

Ensure that the timer on the TV that switches it off after a period of non-use is turned off.

Turn Off Auto Power Off: 

The auto power off feature is turned on and it should be switched off if possible.

Step 5: Update Firmware or Reset TV

Solution:  

If the concern involves software or firmware, go through these steps.

Check for Updates: 

Search to see if a newer version of the firmware is available. 

If there’s an update available make sure you download it to help the TV work better.

Factory Reset: 

When nothing works, the next option is factory reset. This reset would revert the changes done since the last usage and often helps in resolving software clutches. 

Take care of all the useful files or settings that have been saved before this type of reset.
