Press the Power button on it, and on the TV itself.
If not:
• Check that the power plug is securely inserted into both
the AC INPUT socket on the TV and the wall outlet, and
that both are switched on.
• Check that power is available from the power outlet by
trying another known working appliance (e.g. desk
lamp) from that same power outlet.
