There was a power outage today and now the tv wont turn on not even the red light and tried disconnecting and everything, nothing happened , other tv is working as normal how to fix it? Tv less than a year old and samsung says it might not cover since it was an outage.
Is this a good question?

Don’t know the TV but if the TV’s power board “board” number is BN44-00876D, verify that the fuse specifications say T4AH 250V.
If so the T indicates that it is a timed fuse (aka slow blow).
It is important that you replace the fuse with the same type i.e. slow blow, because if it is replaced with a standard (aka fast acting) fuse the fuse could blow straight away when the power is applied due to the current inrush, whereas a slow blow fuse will hold until the current inrush has passed. We’re talking milliseconds here.
When ordering a fuse ensure that you order a T4AH 250V slow blow axial fuse -supplier example only to get the correct one.
Also the surge suppressor next to the fuse may have been damaged as well.
Here’s an image of the power board from your model TV (if it is the same?) where I’ve enlarged the section showing the fuse and its specification. I’ve also shown the MOV surge suppressor that should be inspected for any damage. If it is damaged hopefully you can discern the markings on it to find out what value replacement to get.

Hi @alexdrenea
With power connected to the TV check if there is voltage on the STB (standby) voltage reference point on the power board.
Here's an image of the board showing where to look.
Be safety aware when testing as there is lethal exposed AC voltage on the "hot" side of the board.
When power is applied to the TV a STB voltage signal is sent from the power board to the mainboard to indicate that power is available. It is the mainboard that turns the red power LED on.
If there's no voltage or the incorrect voltage on the STB ref. point then there's a problem on the power board. Unfortunately I cannot find a schematic for the board. You may have better luck. If the STB voltage is correct then it may be the mainboard. Was the TV on at the time the power failed?

Power outages are often preceeded by very short power spikes. It is quite possible that one set has been damaged by a power spike. That being said... if you donot even have the red standby light, the main internal fuse may be blown. This could be a simple fix. If you feel comfortable opening up the back, do so and check the fuse. Lets start there before any other attempts.
Please post the model number of the set too so we can provide detailed information.

Can you tell me what fuse I would require, I have the same problem after a power outage no standby light.
Model number is
UE55MU6400UXXU
Thanks for any help

You will need a 5A 250V pigtail fuse. Open up the back and you will see the fuse right above the AC inlet.

I know this is a reaaly old post but this just happened to me last week!
EXACT same symptom as posted and incidentally, I have the exact same Power Supply (BN44-00876D) that @jayeff mentioned.
I checked the fuse and it looks like it's not blown (able to test with a multimeter for continuity).
Anything else I could check for? How do I check the surge suppressor next to it? Looks fine to me but not sure what I should be looking for.
Thanks!
