If the power indicator is blinking on the front of the VIERA, turn off the TV and unplug all HDMI cables that are connected to the TV. Then unplug the power cable from the current power source. Try a different electrical outlet. Remove the power cable from the rear of the TV and plug it back it in (the power cable tab is inserted correctly when you hear a click).
Just unplug the tV from AC powwer wall socket, let it be at theis state for about 30 minutes, replugh the TV only, and check whether the fault rectifes. OK.

The other day when you go to turn the tv on it takes about 2to3 min. for the picture to come on. But yesterday a new problem started now when you try to turn it on the green powwer light comes on then...

Your problem definitely relates to the Capacitors on the power board.
Common and WIDESPREAD issue that Samsung refuses to acknowledge.
The capacitors bulge and may leak fluid, they require replacing with higher voltage caps. Call a service tech if you are uncomfortable with replacing them yourself.

If that fails, you will have to replace the entire power board, they are available on the net for approx $100.

Good Luck

My TV worked fine this morning,Turned it off,Went back to put it on and now it won't turn on at all,Why?

Maybe faulty power switch or its blown a fuse or the powwer supply inside the TV is kaput.
If its out of warranty get in touch with a reputable TV mechanic and ask them to come and repair it. It might be good to get a ballpark figure on how much it's going to cost.
Good Luck
