Hi, Try a power reset.

  1. Turn off the TV
  2. Switch off the power outlet and disconnect the TV power cord.
  3. Press and hold the TV power button for about 30 seconds to dissipate any residual power from the TV.
  4. Reconnect the TV power cord to the outlet and switch on the outlet.
  5. Turn on the TV and see if it starts OK.
