First of all check the power cable is connected to both the TV and power outlet correctly and that no fuses are blown.

Are you needing a replacement?

In order to ensure, it is not caused by the input device, connect a DVD player and see. Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
