Though, power outages and surges can cause electronics to do weird things. If the issue persists, you could unplug the TV at night.
Also, if this is a common enough occurrence that it has become an issue, I would recommend using a surge protector because these power fluctuations are not good for the TV. While unplugging all your electrical appliances during a thunderstorm may sound a bit unnecessary, doing so can protect your devices from damaging power surges.
As a result, your electronic devices will likely be damaged, and your television may not work properly following the surge. If this scenario has happened to you and you now find yourself with a faulty television, don’t worry.
There’s likely a simple way for you to repair it that doesn’t involve any special equipment and won’t harm your TV. To learn how to properly reset a TV after a power surge, follow these easy steps.
By learning how to prevent surges from occurring, you can avoid the hassle of resetting or repairing your television in the future. To resolve this issue, ask your electrician to establish dedicated circuits for each large appliance.
If your home was built before the 1980s, for example, it’s likely unequipped to handle large entertainment systems. A good way to tell if your home’s wiring is inadequate is if fuses are frequently blown, lights flicker or dim when large appliances are running, or circuit breakers trip often.
In addition to potentially damaging your television, such faulty wiring could become a fire hazard in the future. Now that you have ensured that there is a problem with your television, not your electrical socket, you can follow the below steps to reset your TV and get it working properly again.
The first step to properly resetting your television after a power surge is to unplug your TV from your wall outlet so that no electrical power is being provided to it. After unscrewing the cables, plug your television’s power cord back into the wall outlet.
After the menu screen has appeared, select the “Settings” option for your television. On the list of settings, choose the “Options” or “Advanced” tab, depending on your television’s selections.
Turn your television on for a final time to ensure that it’s working properly again. You will have to unscrew the back of your TV and locate the power supply board.
As a secondary check, you can do a visual inspection to look for burns or blown capacitors, as pictured below. The easiest way to find it is to search by each set of numbers on our website.
If your television doesn’t turn on after you’ve completed the steps above, there could be a greater problem. You may be able to visually see the damage to the board, such as a burn or a blown capacitor, that look like the images below.

Reattach the cable to the port on the back it was removed from earlier. Plug the TV's power cord back into the wall outlet.
Turn the TV on with the front or side control panel. Select “Factory reset” or “Factory default” from the list of choices presented on a new screen -- the actual name may vary slightly, depending upon the manufacturer of the TV.
