7 things that accidentally void your Smart TV warranty

Your Smart TV warranty is a safety net, meant to protect you if something goes wrong. However, you can accidentally void your Smart TV warranty without even realizing it—even if you're doing something completely normal.

Moving the TV the wrong way

 

Smart TVs are often fragile and their screens can easily crack during transport. The standard warranty only covers manufacturing defects, such as if a part breaks due to a mechanical fault. However, it does not cover damage caused by accident or misuse, including scratches, dents, chips, or scrapes caused by bumps or drops during transport.

So to keep your TV safe and your warranty from being affected by other potential problems, handle it with care. Get at least one extra person to help you move large screens – they're hard to carry alone and can be harmful to your spine. If you hire movers, make sure they actually know how to handle electronics.

Electrical failure

Most TV manufacturers include electrical damage provisions in their warranties and when looking at major manufacturers this will be confirmed. For example:

1. LG's warranty explicitly excludes damage caused by excessive voltage.
2. Likewise, Sony's warranty lists overvoltage as one of the excluded causes.
3. Samsung follows suit, with its standard limited warranty also excluding such damage, although an extended warranty, Samsung Care+, covers it at an additional cost.

 

This is just a handful of the major Smart TV manufacturers, but it's common across the industry. These companies want you to protect their products from voltage fluctuations that are completely out of your control. It may seem unfair, but from the manufacturer's perspective, they don't want to replace thousands of TVs that are damaged by a local power outage.

Using unsupported third-party accessories

 

Just because an accessory fits well doesn't mean it's safe. If it damages your TV, you're the one who's going to suffer the consequences. Let's say you buy a super cheap wall mount that's supposed to support the size and weight of your TV. It might look fine at first, but if it breaks and your TV falls, you're not covered by your TV warranty.

Likewise, if you use a third-party power adapter that is not designed for your TV, it may not provide the correct voltage or current. This could damage the power supply or other components of the TV, such as burning out the motherboard. The manufacturer may conclude that the power adapter caused this, so they will void the warranty.

Placing TV in extreme conditions

 

Major TV brands like Sony, Philips, and Samsung give some pretty specific operating specifications in their manuals. Most of the time, they recommend keeping your set comfortably between 50°F and 104°F (that's 10°C to 40°C, with humidity below 80%).

Take Philips, for example – the Philips Support page states that ideal conditions are 5 to 40°C (41 to 104°F) with humidity between 10% and 70% (as long as the moisture doesn't condense into tiny water droplets). Meanwhile, on Best Buy's Q&A, Sony's Insignia TVs are confirmed to thrive in the same temperature range of 5 to 40°C. In short, keep your TV away from extreme temperatures. The same goes for humidity.

Installing unauthorized software or jailbreaking

 

The appeal of jailbreaking your TV may be that you want more apps, more freedom, maybe even the ability to download a streaming service that your TV's app store doesn't support. But the harsh truth is that TV manufacturers really don't like it when you push the limits. If, during or after tinkering with your TV's software, your TV starts to malfunction, turns itself off during an update, or suddenly refuses to connect to Wi-Fi after you've tinkered with it, you've voided your warranty.

Unfortunately, even if your software modifications don't directly cause the problem, the fact that you changed the operating system is enough for the manufacturer to void your warranty claim.

Physical modification or self-repair

Physical modification is any change to the original state of the TV that goes beyond normal use. Manufacturers are pretty clear (and stubborn) about this. If you open your Smart TV – even just to 'watch' it – you'll almost certainly void the warranty. If you break the factory seal on the back, you'll be responsible for the damage.

Not registering warranty or keeping proof of purchase

Proof of purchase, such as a receipt or invoice, is the foundation of any warranty claim for your Smart TV. This serves as proof of ownership and date of purchase, both of which are necessary to verify warranty eligibility. Without this documentation, the manufacturer cannot confirm that the TV is under warranty or that you are the original purchaser, and in fact, the warranty will be void.

The limited warranty, which is standard on most Smart TVs, operates under slightly different rules. The manufacturer may require you to register it, but they're legally obligated to disclose it. And even if you skip the registration part, your warranty won't go away as long as you have proof of purchase.

Some brands still imply that registration is absolutely mandatory. Consumer groups like Consumer Reports have called this out, pointing out that it's often just a sneaky way to get your personal information. So don't let them guilt you into handing over your data unless it's absolutely necessary.
