Help with samsung tv

I have a 50in Samsung model # UN55EH6030F. When I turn the TV on, it will come on but as soon as it starts to show the blue screen with the Samsung logo, (so maybe around 5 sec.) It will turn itself off. Can someone please tell me what might be wrong with it? Please and thank you...

Can only guess.

But that sounds like the LED or other parts have shorted or over-currented and the TV shuts down. It's not considered user serviceable but you can find YouTubes about how to test the LED strips.

Just for clarity.

I've had techs tell me it's not the LED strips because "I can see the Samsung logo" or more. I don't have patience so I give a nod to my senior tech to give the rundown on this area. This is a typical issue so I can only share it so you can go get the YouTubes about it, how to test LED strips and how you can unplug them to sniff out if that's it.

Even so, this may be too much for first time TV repair folk to get into but I share anyway.

sounds like the power board

On youtube there's a "tampatec" user who does this work and plenty of videos about it, shows the various internal workings and how to repair them.
