How long do LG TVs last?

One of the greatest benefits of purchasing an LG television is the access to numerous channels that offer music, movies, shows, and more, without ever needing to connect your unit to antennas or buy expensive cable service subscriptions.

Another major benefit of this television brand is access to compatible media content, gaming opportunities, and Internet browsing.

All these available features mean you will likely be using your television regularly for different tasks, so it must last. 

The general rule of thumb for this brand is moderate users can expect longevity of 7-15 years, with it being common to surpass 15 years because of the high-quality components used by the manufacturer.

How to make an LG TV last longer?

Prolonging the life of your television is certainly possible by taking the following steps to ensure it remains in top condition:

Check the brightness

The higher the brightness level you use, the faster your backlighting components burn out. Therefore, it is important to set the brightness to the level recommended by LG.

Clean and maintain your TV

Start and follow a routine of keeping your TV as clean as possible to ensure it’s not full of debris and dust. For the screen, use a microfiber cloth to gather any dust particles. 

During the cleaning process, utilize compressed air to blow dust out of the vents, which can limit airflow when clogged, and never use chemicals on these sensitive components.

Ensure you turn off your television after use

Always turn off your TV when not using it. The backlight on your model is one of the first components to go because heat pools and causes it to burn out, thus rendering the hardware useless.

Some LG televisions have integrated timers to automatically shut off at specific times. Look for this feature in the manual and use it to help prolong your investment.

Put the TV in the right location

Make sure to keep your television away from the window so sunlight so that inclement weather doesn’t cause damage. Also, don’t keep your television near an appliance that produces a significant amount of heat, which can also cause overheating issues. 

Furthermore, place your television in a location where plenty of airflows exists, so it will keep the backlighting cool. 

Wall mounts are an excellent option since they prop your set against the wall away from heat sources while providing plenty of airflow between the wall and the back of the TV.

Use a power strip

Unexpected power surges have been known to completely fry a television, which means you will have to purchase a new unit. 

A power strip or surge protector absorbs extra surges and can save your television from burning or breaking the electrical parts.

Implementing these simple steps can help prolong the life of your LG television by several years, if not longer.

Common causes of LG TVs breaking

There’s nothing worse than sitting down to watch your favorite show after a grueling day at work and having the screen pixelate, block, or freeze. 

When you have a hardware problem or an issue with your cabling, many complications can lead to a broken TV, including:


Burn-in is a common issue that arises when a static image sits on the screen for a considerable time. The pixels essentially become stuck in that fixed position, thus leaving a permanent image or shadow.

While TV manufacturers have added features to eliminate this issue, it still occurs with gaming, menu screen, or when borders appear around programming.

For this reason, you should always turn off your television after use.

Extreme Temperatures

Extreme moisture, humidity, cold, or heat can permanently damage your LG TV’s flat-screen display. 

Humidity will short circuity the internal wiring of the television while extreme cold or heat disrupts the proper changing of color pixels.

If you must store your television for an extended period, then it’s ideal to keep it in a climate-controlled location.

Hardware problems

The component inside of an LG television is complicated and extensive, so many issues could arise. The most common issue, because it’s the first component to die, is backlighting problems. 

The backlighting provides the light behind the screen, so you can see the picture in a variety of intensities.

If the backlight overheats due to excessive use, not enough airflow, or is just old, it needs to be replaced for the television to work properly.

Inclement weather

Inclement weather is another cause of LG TVs breaking. If lighting strikes an electrical pole and runs inside through your wiring, it can fry the television. 

Surge protectors were designed to catch the excess electricity from a storm, so if you’re not using one, your set is at risk.
