Samsung UN40MU6290 won't turn on sometimes

I don't know what is up with my TV. Sometimes it won't have power at all (not even the standby light is on). The outlet has power and the cord going to the TV has power. The cord is plugged into the TV completely. It just won't turn on. Then randomly it will fix itself and I'll notice that it is back in standby mode and I can turn it on. It just happened to me for the third time recently where I couldn't turn it on all day yesterday but now today it will turn on.

What could cause this? Is there some sort of safety feature or something that prevents itself from turning on? I have had the TV since late December so it's still under warranty. Maybe I should exchange it at Best Buy for a new one?

Any thoughts?

P.S. - this TV doesn't have any actual buttons? It's strictly controlled by the remote?

Power board, check the relay. If under warranty, I would exchange it.

bulb save money by checking your insurance every 2 years (and not every 20) Thanks Liberty Mutual for reminding me to shop. The $842 increase this year sums it up. Across the board increase for Ohio....whatever
