Power outage then wont turn on

Faulty or worn internal surge protector. External surge protection recommend.

there is a surge protector on the main power board this has probably blown. or the main power board fuse or plug fuse. check them one by one. there even may be a secondary fuse in the tv around 3amp witch can blow. it will have red and black lines on it or orange that is the rating of the fuse. surge protector is like a battery shap round with 2 prongs onto the board.

Power surge protectors don't always work 100%.
Hopefully the TV has internal Diode protection and it can be fixed cheap

try cycling the power (unplug 2 minutes) and plug in and wait 30 seconds and turn back on. if this doesn't work, could have been a surge, your protector should have saved it, but could have been through cable or something. surge protectors will guarantee no damage for several years, check with the manufacturer maybe they'll cover the repair.

I had a similar problem when there was a power outage or the lights went briefly out. I unplugged the TV and left it for a few days/weeks and then plugged it in and the TV worked. I think newer TVs should be treated like a home computer and put them on surge protectors.

A lot of times its simply a fuse that goes out. Either way someone is going to have to open it up and inspect the fuses first. It 's a fairly inexpensive service call.

Hopefully the fuse took the hit from the storm.

Laptops are far more prone to be taken out by even minor power surges then anything else in your home, including desktop computers.
If you have any method (multimeter etc) to check the voltage from the power supply you may have been lucky and it took the bullet to save the laptop.
If the power is registering in the correct range, around 18volts, then chances are your laptop has taken the hit and the motherboard is gone.
If this is the case, then before you throw it against the nearest wall, take it to a laptop repair centre. It "may" have been saved by a fuse on the motherboard and therefore protected itself as best it could.
Prices to have it looked at will vary alot, so call around.

have you checked the fuses inside the set. The power outage could have surged just enough to blow the fuse. Dont forget to unplug it when you check the fuse.

LOT OF TIME WHEN YOU LEAVE IT OFF FOR THE NIGHT DISCONNECT POWER CORD DEFECTIVE SURGE PROTECTOR IS NOT GOOD FORE EVER PLUG TV IN THE WALL WITOUT THE SURGE PROTECTOR IF IT GOOD CHANGE THE SURGE PROTECTOR FOR NEW ONE CHEERS

Sounds like the typical power surge created by the outage has caused a power supply problem inside your TV. IF that is it, there not much you can do yourself.
