onn. 65" Class 4K (2160p) UHD LED Roku Smart TV HDR 100021261. Won't turn on, no red light now. Had lightning storm near home. It fried the modem and router however nothing else in the house except this TV. The TV was connected to router by ethernet cord. Can anyone help? Tried power reset, still nothing.
Is this a good question?

Hi @diamond8879
Was the TV's power cord connected directly to the wall outlet or to a power strip?
Have you checked that the power outlet that the TV is connected to is working OK? (plug in a hair dryer and check)
If the power outlet works OK (wall or powerstrip), disconnect the power to the TV and then remove the back cover from the TV and inspect the power board for any damage i.e. blown fuse and/or burnt components. The power board is the board that the power cord connector is connected to.
Post some close up images of the board back here in your question so any damage that you may have missed might be seen etc. Here's how to do this on ifixit. Adding images to an existing question
Also include an image of the power board's board identification information. It will either be printed directly on the board or is on a sticker on the board. This is so a correct replacement may be found if it turns out to be more than a fuse or surge protector on the board that has blown.
Also maybe check your home contents insurance policy. Sometimes it covers events like this. It doesn't hurt to check. ;-)
Was this answer helpful?
Unfortunately it was plugged into the wall outlet. When I noticed the red light was no longer on, I unplugged it, waited like 5 mins and plugged back in, still no power. I checked the outlet with a fan and the plug is getting power. I even plugged TV into multiple outlets and surge protector. I will open the TV up and check the power board. I will send pictures. Its just weird that it seemed as it fried modem/router that was plugged into surge protector in a different outlet and nothing else in the house. Thank you for the response.
Depending on the type of surge protector you have for the modem/router, you may also have to replace it as well.
Briefly most surge protectors are of the sacrificial type i.e. they die protecting the devices connected to them and need to be replaced, whilst the connected device remains unharmed
The trouble is that some of the cheaper end protectors do not indicate that they have operated during a surge event and will still provide power on the outlet after the event has passed. So whilst they have protected once they cannot do it a second time and you are unaware of this, so if another surge event occurs the "protected" device is then harmed.
The next level protector up in price will also protect only the one time but there will be no power through the protector after it has operated during a surge so you know that it has to be replaced.
The higher end in price protectors give an indication, usually a light no longer working on the protector, that denotes it has operated during a surge and also needs to be replaced.
There are higher end surge protectors on offer where the manufacturer provides insurance if the surge protector fails to protect the device attached to it, some to the value of $10,000. I don't know how good the cover is just letting you know.
Thank you for the information. It's just weird because the other stuff plugged into that surge protector at the time works perfectly. It didn't fry the modem/router power supply, (I should note) it fried the signal, where the cable goes into, (so modem wasn't recieveing the signal from cable company) on router it fried the ethernet ports. And tv of course because it was hard wired. Almost like the power surge came thru the cable cord and ethernet. Tv wouldn't turn on after that. But I will get it opened up and look at board.
It's not unknown for lightning to hit the ground and flow through any cables buried in the ground nearby.
Worked for the phone company for 45 years and had several instances of the phone (corded phone) being badly damaged due to lightning traveling up the phone cable. Have also seen household power boxes which were blown up due to lightning hitting the overhead power lines and once where it hit the ground and they had underground power to the premises.
The phone company here used to advise that people not use their phones during a storm for that reason, to prevent getting an electric shock or worse. They still do but its buried in the phone book and nobody reads that anymore or they have cell phones instead ;-)
There are power boards (powerstrips) available where not only are the power outlets surge protected they also have a feature where you can run the internet cable connection in and out of the powerstrip to get to the modem and this goes through a surge protector also i.e. connecting cable from internet connection point in premises into powerstrip - through surge protector in powerstrip - connection cable to modem line input
I figured out finally why mine would not work out of the box. I opened he back of the tv and the wire was not completely plugged in. I plugged it in and works great now
