Smart TVs are supposed to stay plugged into an outlet. Even when turned off, they are usually in a low power state. You may not realize it, but this puts your TV at risk, however small. At any time, a power surge can damage the internal parts of your TV, including the power supply and capacitors; any parts that use electricity could be in danger. It’s always a problem when components fail, but data corruption due to storage hardware failure can be particularly troublesome. And a power surge could easily damage flash storage.
When data corruption occurs on a TV, the device may get stuck in a boot loop with the screen on but nothing displayed, apps may fail to load, the system may experience frequent crashes, and other elements of the TV may stop working altogether. Additionally, some of these issues are not necessarily attributable to storage. Turning on the TV to a perpetually blank screen might make you think it’s a display problem. If a power surge physically damages the storage, it likely cannot be repaired without professional help.
You can try a factory reset or search the manufacturer’s website for manual firmware update options; If possible you can update the firmware to see if that restores the base data or at least refreshes it. Otherwise, the best defense occurs before a push. This is also why, aside from unplugging your devices, one of the easiest ways to protect your technology from power outages is to back up your important data as much as possible.
What is data corruption in TV?

Modern smart TVs often include software and streaming technologies, designed to enhance your entertainment experience. Like any software, it must be stored somewhere, usually a small NAND or flash chip inside the device, called flash storage. If this storage fails or is damaged during a power surge, that’s when data corruption can occur. Data becomes garbled, unreadable or fragmented, meaning the TV can no longer access it and the resulting software and applications no longer load.
Data corruption, in itself, is a fairly common problem that affects computers, mobile devices, gaming consoles, and anything that uses a storage drive. A powerful power surge can effectively fry components inside a TV, including storage, while minor, repeated power surges could also damage it or cause components to overheat. When a power surge physically damages components, from internal storage to the motherboard, there isn’t much recourse other than repairing the parts, either by a DIYer or a professional, or replacing the TV.
Why do power surges occur and how to avoid them?

In American homes, outlets should theoretically provide a constant voltage of 120 volts, but alternating current (AC) realistically fluctuates over a range of 0 to 169 volts. Most electronic devices are designed to handle these minor changes; however, huge and sudden spikes are another story. Certain events can cause this voltage to rise well above the peak of 169 volts, which is when a surge occurs. You’re probably familiar with a lightning strike, which is one way a power surge occurs, but there are actually many other, more common events that can cause it.
Power surges can originate from the utility company during maintenance or can occur on the grid for a variety of reasons, such as a blown transformer or infrastructure outages. They can also occur in your home due to electrical outages or simply when high-wattage appliances turn on or off, such as an air conditioner. Often, when a circuit breaker trips or actively trips, it is due to a power surge. Surge protectors are your best solution.
A surge protector is inherently designed to protect your electronic devices from unexpected electrical events, hence the name. It’s always a good idea to plug your most valuable devices into a reliable device, although you should look for rugged options that offer better protection. Heavy-duty options have built-in circuit breakers to divert power surges; this is why some power strips have a reset button. You can also unplug your most important electronics during a storm, although it’s not always possible to unplug everything manually. This is why surge protectors are a great help.
