Out of the myriad of things that can happen to your television, a power surge could be one of the worst.

All appliances and electronic devices have their limits. Just like them, wall circuits or electrical outlets are no different.
When there’s too much electricity being passed on and surged, there’s a big chance that it can cut the power off or worse – damage and break your devices.
Did you know that appliances and electrical devices that require high energy are notorious for power surge causes?
Huge chunks and amounts of powder are drawn from these, and therefore, they can spark up and initiate the power surge that you did not expect.

Little did we know, power outages are also a cause of a power surge. This happens because when the power turns back on, the amount of electricity distributed could be different – it could be higher.
It’s common to note that exposed wires and cables are a cause of concern. That being said, the electricity that’s transported could be unbound all throughout your entire living space.

One of the signs that your television needs fixing after experiencing a power surge is that it’s not turning on.
So, is there something you can do to resolve it? Here’s the process of how you can fix your television if it’s not powering on succeeding a power surge.
The first and the most basic step that you want to do is to test the wall outlet where the TV is connected.
You can try plugging in your phone charger to see if it would charge.
After that, you would want to drain power from the television by unplugging it for about five minutes.
Keep it unplugged in order for the electricity to stop circulating within it.
Then, disconnect all cables and wires connected to the TV. This would include:
- HDMI cables attached and connected to it
- Speakers and subwoofers
- Streaming devices
Note: You need to get rid of and remove everything connected to it.
Different television brands would have different methods of factory resetting. In your part, you have to know how to reset it.
Most televisions would have a Reset button anywhere at the back of the TV. Alternatively, you can try to go into your TV’s settings to initiate the reset.
Since we’re talking about “power,” it would be worthy to take a look at the television’s power supply, too.
Don’t worry, oftentimes, your television would still be repairable even after it’s hit by a power surge. You just need to do the right things to make it work.
You’ll often find your television’s power supply at the middle part of the board at the back. It’s a component that has a lot of transformers with capacitors and integrated circuits.
Here’s the process on how you can do that:
- Avoid overloaded wall outlets when doing this.
- Plug in and connect the TV to power.
- Set your multimeter to DC.
- Depending on every pin’s voltage, check the multimeter if it gives the same value.
- Locate the pin that is either not giving any value or is short of what’s indicated.
You’ll be able to find and purchase whatever part it is you need from your local electronics shop.
The power board is among the components of a TV that gives it life. And if you’ve experienced a power surge, it could actually be where the damage is.
Similar to capacitors and ICs, you’ll find power boards easy to get, especially if you’re near a service center.
NOTE: Unless you’re knowledgeable and experienced in this field, it’s recommended that you contact a local electrician or expert about it.
If you’re able to carefully follow these steps and your television still refuses to turn on, the next best thing to do is to check the TV’s interior.

There are instances where the power cord is the component that gets damaged during a power surge. You might not see it, but the wires inside it could be ruptured.
So, try using a different power cord to see if it will work.
NOTE: Plug it only on an outlet that’s safe.
If you’ve done the 6-step process and you’re still not getting anything from your TV, the next best thing to do is to contact a local electrician or TV expert to help you.
They don’t have to be from your TV’s manufacturer. So long as they know what they’re doing, you’ll be able to get what you’re looking for.
