Solution
Unplug the power from the wall plug and press the power button on the TV itself (not the remote) for about 10seconds. Replug the power and try powering up again.
Any LEDs blinking or similar?

Which TV model is it? Have a look at the label on the back of the TV and post the exact model number.

Warranty? RMA it

The cause is most probably parts of the power supply inside the TV are broken.
