Does your plug have a reset on it?
No!
No! But I am going to check the power supply Thank You!

I have an element flat panel and the power went out. I opened the back and checked the power board for burnt components and blown capacitors. I found a blown cap. I removed the board, unsoldered the bad cap and soldered the replacement to the board, plugged everything in and voila power restored!

Describe the past - How did it fail? One day or acting up for a while? Could be a weak power supply - a bad capacitor on a power supply too. Look for popped up capacitor top inside.

If
it's failing to turn on, the main power supply is probably at
fault and without some technical background and a couple of test instruments,
you will not be able to do the repair yourself.
What you can do though is; unplug the set, let it
stand overnight or at least several hours, remove the back panel and look for a
separate board with mostly larger components on it; it will have a ferrite core
(no laminations as with a line-frequency part) transformer on it and several
larger capacitors which are cylindrical and mounted vertically to the board.
Before touching anything inside, especially on
that board, allow several hours to be safe since the larger capacitors can hold
a painful voltage charge for some hours.
If you see signs of overheating such as
discoloration of the board material, it may not be repairable but if you can
find a part number on the board, you might be able to buy the power supply and
install it yourself but it will likely have the same problem eventually unless
they have altered the design.
If there are no signs of heat damage to the board,
there may be companies offering to repair it as a subassembly instead of
repairing the whole set which could be much more expensive.
If you choose to replace or have it done, the
power supply still may not be at fault since most are capable
of switching on and off if a downstream problem is causing an overload.
Another possibility is a close lightning strike and the factory surge protection is not up to preventing damage from those.
