|How is the Viera getting its tv signal - Sky or Virgin satellite box, or Freeview antenna system?|
Have you verified the Viera is selected to the correct input signal source?
Is this a recent problem, as in everything was OK and now not so?
Is there a network cable and thus an internet connection - which is providing the iPlayer signal/output?
Not having anything like the Viera I may be asking for details which might be familiar to anyone who has one. I still have and view a good old reliable Panasonic 24ins glass box (crt set).
