Tips to protect and extend the life of your TV

💡 Need to know

• The average TV lasts 7 to 10 years before experiencing noticeable dimness or component degradation.
• Summer is peak breakdown season. According to Asurion claims data, more TV issues are reported in July than any other month, closely followed by June and August.
• Simple maintenance prevents major failures. Using high-quality surge protectors, adjusting brightness settings, and ensuring proper ventilation can double your TV's lifespan.

Modern TVs are incredibly reliable compared to devices from years past, but they aren't invincible. In fact, according to Asurion claims data, your television is actually more susceptible to problems during the summer—more issues are reported in July than any other month, with June and August right behind.

Summer thunderstorms and power surges are likely causes of the seasonal spike, but the experts on our team who are parents suspect another culprit is also to blame: kids being home from school for the summer, testing the absolute structural limits of your remote control, and logging marathon hours on their gaming consoles.

Don't worry, though. There are simple things you can do to keep your screen running beautifully throughout the year. Here's a guide from Asurion Experts on what to expect from your television's lifecycle and exactly how to protect your investment.

How long should a TV last?

Whether you own a standard LED, a premium QLED, or a cutting-edge OLED television, you can generally expect a TV to last between 7 and 10 years under normal viewing conditions.

Unlike older tech that would suddenly burn out completely, modern flat panels slowly lose their peak brightness over time. This lifecycle is measured in operational hours:

• LED and QLED TVs: Typically rated for 40,000—60,000 hours of peak performance.
• OLED TVs: Rated for up to 100,000 hours before the organic pixels degrade to 50% of their original luminance.

Because display engineering moves so quickly, the reality is that you will likely choose to upgrade your TV to a newer smart platform or a higher resolution long before your current panel actually gives up.

4 tips for preventing problems & damage to your TV

To help your television make it past the decade mark, implement these four expert maintenance habits.

1. Use a high-quality surge protection device

Electrical surges are the leading cause of sudden motherboard and power-supply failure in modern televisions. To protect your investment, never plug your TV directly into a standard wall outlet. Always route your television and its peripherals (streaming sticks, soundbars, gaming consoles) through a high-quality surge protector rated for consumer electronics.

While summer thunderstorms and grid brownouts are common culprits, they aren't the only threat. Every time your refrigerator, air conditioner, or clothes dryer cycles on, these power-heavy appliances send micro-surges back through your home's electrical wiring. Over time, these repeated small spikes degrade your TV's delicate internal capacitors until the unit refuses to turn on.

2. Optimize your brightness and contrast settings

Leaving your TV on its default "Vivid" or "Showroom" mode strains the display panel. Higher brightness requires more electrical current, which generates excessive internal heat and accelerates pixel aging (especially the blue organic material in OLED screens).

🛠️ The fix: Switch your picture mode to Standard, Eco, or Movie. Lowering your backlighting or panel brightness by even 20% dramatically reduces power consumption and extends your TV's operational half-life.

3. Clean and dust your TV screen safely

Dust buildup acts as an insulating blanket, trapping heat inside the chassis and clogging the ventilation grates that cool the internal processor. Clean your TV regularly using an anti-static microfiber cloth.

⚠️ Warning: Never spray commercial glass cleaners (like Windex) or water directly onto the screen. Liquid can easily drip down into the lower bezel, instantly short-circuiting the display's ribbon cables. For a complete safety breakdown, check out our guide on how to clean your TV screen without damaging it.

4. Ensure proper climate control and ventilation

Using or storing your TV in areas exposed to high humidity or drastic temperature swings will shorten its lifespan significantly.

• Indoor placement: Ensure there is at least 2 to 4 inches of open space between the back of your TV and the wall or entertainment center to allow proper heat dissipation. Avoid mounting a television directly above a working fireplace.
• Outdoor TVs: It's not smart to use standard indoor televisions on an outdoor patio or porch. Moisture from humidity will cause rapid internal corrosion. For outdoor setups, invest in a purpose-built, weatherproof outdoor display.

FAQ

How long should a TV last?

Most modern TVs can last anywhere from 7 to 10 years or more. How long yours lasts depends on factors like usage, maintenance, and how well it's protected from heat, dust, and power surges.

Does turning my TV off extend its lifespan?

Yes. While TVs are designed for regular use, turning them off when you're not watching helps reduce wear over time and can lower energy consumption.

Can dust damage a TV?

It can. Dust buildup around vents can trap heat and make internal components work harder. That's why our experts recommend cleaning your TV and its vents a few times a year.

Should I use a surge protector with my TV?

Absolutely. A surge protector is one of the simplest and most affordable ways to protect your TV from power spikes caused by storms, outages, or electrical issues.

What's the best way to clean a TV screen?

Use a clean, dry microfiber cloth. Avoid paper towels, household cleaners, or spraying liquid directly onto the screen, as they can damage protective coatings.

Does high brightness shorten a TV's lifespan?

Running your TV at maximum brightness all the time can create more heat and put extra strain on the panel. Lowering the brightness to a comfortable level can help reduce wear while still delivering a great picture.
