My LG TV Keeps Turning Off Every 5 Seconds [Fixed]

After an exhausting day, there is nothing more relaxing than lying down on the couch and turning on your favorite show on the LG TV. 

However, it can be more than annoying to have the screen of your LG TV turning off every five seconds. 

Of course, all that you wish is to relax and not have to constantly interact with the remote just to see the next episode or for the movie to go through. 

This article explores possible causes for this phenomenon and offers step-by-step assistance on how to resolve this problem.

Understanding the Issue

Why Does My LG TV Keep Turning Off?

Software Glitches: 

Software bugs are one of the most common factors that could cause your LG TV to turn off every 5 seconds. 

A firmware update should enhance an existing feature, but at times it does the opposite and adds a bug that operates devices in a way that is not desirable. 

The TV can have performance issues such as violent on-off once it has reliable but old software or it has been corrupted.

Power Supply Issues: 

Your LG TV has a power supply unit (PSU) and that powers it on, it’s one of the most essential components. 

If the power supply unit (PSU) has issues such as fluctuation of voltage levels or damaged parts, there is a risk that the TV may jolt off and back on several times during a hub. 

In some cases, an overload of power or disconnection of power adds to the PSU burning and damaging it which causes more issues.

Overheating:  

Recent editions of any electronic device, LG TVs included, have procedures that avoid any damage due to excessive heat to a great extent. 

However, in some cases, if the TV is placed in a compact, congested area, or if it is filled up with dirt and dust. 

Overheating and thereby shutting down will occur to save the gadget from further damage.

Remote Control Problems: 

It is not uncommon for the remote control rather than the TV itself to be the source of a problem. 

A broken or jammed button on the remote may cause it to emit signals that would unsafely switch off the television in most cases. 

Such a scenario can trigger the TV to turn off when it is still in use without the owner’s consent.

External Devices:

If there are external devices attached to the LG TV, such as a gaming console, external sound, or similar devices, it could be any of those devices that caused the problem. 

For example, an exposed HDMI wire may send disorderly signals that can result in the devices shutting down altogether.

Hardware Failures:

LG TVs, much like any other electronic gadget, bear the risk of hardware breakdowns with time and service. 

LG TV’s hardware set breakdowns can be a possible cause of such failures such as components capacitors mainboards or simply wire connections.

Troubleshooting Steps

Step 1: Check for Software Updates

First of all, see if the software on your LG device is current:

Access Settings: 

If possible, switch on your TV and press the Settings button on your remote control.

Navigate to About This TV: 

From the end of the Options and Settings menu, pick All Settings and then About This TV or Support.

Check for Updates: 

Search for an option that reads “The updates will characterize this”: in that case, yes, there may be one. If so, go ahead and update it.

Step 2: Inspect the Power Supply

The first step if the television has shut down again would be to check the power cord:

Examine the Power Cord: 

inspect the power cord for any external damage. Check for any cuts, breaks, or signs of wear and tear.

Test the Outlet: 

To exclude the possibility that it is the socket at fault, unplug the television and plug it into a different socket.

Use a Surge Protector: 

If you do not already employ one, it would be a good idea to plug your television into surge protection.

Step 3: Ensure Proper Ventilation

To avoid overheating, check the following:

Check TV Placement: 

Do you keep the TV inside a cabinet or against the wall? As a rule of thumb, the TV should have several inches of space around it on all sides.

Clean the Vents:  

Dust settles in the vents and restricts the flow of air. 

A gentle brush or a vacuum with a brush attachment can be used to clean off the vents.

Step 4: Investigate the Remote Control

To eliminate the possibility of remote control issues:

Tweak the Remote Control: 

Disconnect the batteries from your remote control and press each button to make sure they are not stuck in place.

Try Without Remote Control: 

Use the physical buttons present on the TV in order to turn the television on and off to check if it still turns off automatically.

Step 5: Disconnect External Devices

If the above action does not work and the television continues shutting itself then remove all peripheral devices.

Unplug the HDMI Devices: 

Disconnect any HDMI devices, or other such devices connected external to the TV, such as gaming devices or streaming devices.

Look and Check the Wires: 

Check the wires for any cuts or ruptures. If able to, see if other wires will have the same outcome.

Step 6: Perform a Factory Reset

If the above measures fail to be effective, it is suggested to initiate a factory reset.

Go to Settings: 

Using the remote control, click the Settings option.

The Panel Resets: 

Click on General, and scrolling down the panel, look for the option that allows resetting the initial settings.

Proceed to a Final Confirmation: 

Follow all instructions until the final confirmation is reached. Be aware that this will remove all the configured settings and saved data.

Step 7: Seek Professional Help

If your TV still believes it has a sleeping problem and turns off every five seconds, as it is doing in this case. 

We would recommend contacting LG customer support or your professional technician. 

Faulty components within the TV set may require special tools, and some experience as well in diagnosing and fixing them.

Personal Anecdote: My Encounter with the Same Issue

I endured what many have; my LG television set ceased to function every 5 seconds. The very first time was during a key playoff match. 

The first was, I assume, a small issue. I attempted to disregard it but the television wouldn’t let me. 

It would go off with the scores being on the verge of a change. It disheartened me time and again.

After some banging of the remote like it was supposed to help in the first place that deregulated any hopes, I pulled my fingers into the repair process. 

There is no proper manual for all sorts of trouble: the first thing to do when an update is available is to check for that. 

Fortunately, I sat down to check on an update because there was one and I put it in. The television acted right for some time but then came back with the issue again.

I have to say it was a little while, but by pulling each part apart one at a time, I came to the conclusion that the power supply is what it is.

I was lucky; a quick trip to my local electronics shop for a new cable did the trick. 

That experience was a revelation for me about needing to educate oneself about the technology one uses on a day-to-day basis, and not excuse panic at the first sign of trouble.

FAQs

Why does my LG TV continue to turn off by itself even with a factory reset applied to it?

For instance, if a user applies a factory reset to their LG TV or smart TV only to find that it keeps on switching itself off automatically, it might be a sign of developing internal hardware defect. 

Possibly, a power supply that is not supplying efficient energy, failing internal circuitry or even the motherboard of the television is having technical issues.

Is it true that LG TVs can be irreversibly harmed by overheating?

Such conditions where overheating occurs for extended periods will damage the LG TVs or lg washer and dryer permanently. 

This would lead either to faulty units or, at worst, a complete equipment failure. 

One should always ensure that there is ample space for the air to flow inside the unit and the air vents should be dusted frequently.

On average, how long do I have to wait until the calibration of my LG TV’s software is complete?

In such cases, users may find it helpful to look for the software update two to three times a year or at the least request an update upon noticing delayed performance. 

Regular software add-ons are distributed amongst the users due to the proactive and efficient team of managers at LG who focus on improving the quality of service and removing errors.

Should my LG TV be left on standby all the time if it tends to switch itself off?

In such cases, it is better to stay away from your TV until the cause of the switching is found and fixed. 

Continuing to use the device in this manner can further aggravate the problem in the device increasing the extent of damage suffered.

What action should I take if I have a problem with the remote control?

In particular, if you think that your remote is the source of the problem, start troubleshooting by changing its batteries first. 

If this does not work, get a new remote control or reset the old one if it is not working at all.

Conclusion

It can be very frustrating to deal with an LG TV that turns itself off every five seconds. Knowing the potential triggers and systematically troubleshooting can help resolve this most of the time. 

Whether it is a software update or a hardware failure, do not despair. All issues are solvable, especially those with technology. 

With a little bit of time and effort, you can again enjoy your television without interruptions to watch your favorite movies and shows. 

However, if nothing works, do not be afraid to seek the services of an expert. It is worth it for your entertainment!
