In order to ensure, it is not caused by the input device, connect a DVD player and see. Also look for any loose contacts in power outlet, RC jack, cable and socket. Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, I suggest it is better to refer it to a qualified service technician, since the back cover has to be opened for investigation/rectification.

Sets new?! Hook up antenna that works?
If nada, have them pick it up and exchange it for a new, hopefully working unit.
Take no prisoners!!!!!!
