No, the NS-55D510NA19 is not a smart TV. There is no wireless or wired network option built into this model. The specifications are available here: https://www.insigniaproducts.com/pdp/NS-55D510NA19/6172325 . I hope this helps. Cindy Wells

Here is the board you should need, its even somewhat reasonably prices, replace that and your TV should be good as new again. http://www.shopjimmy.com/samsung-bn44-00329a-power-supply-unit.htm

Try unplugging and waiting about a minute and then plug it in again. If that doesn't work then it's probably a problem in the power supply.

Probably shorted LEDs behind the screen. Probably you can unplug the lights and see if TV stays on. There is quite a lot of Info on the Net on how to change them actually. Some tvs I just order a strip of them and just solder in new ones.

need the model number please

Sounds like LED strips are bad

There should be a power button on the unit itself
