I think you will do much better pursuing this with the manufacturers or the people you bought these things from (tell me you didn't buy this over the internet...)

I am tempted to say "what does the manual say," but I have to assume you checked it out thoroughly.

Please supply model numbers. I can't imagine that Mikomi makes only one model of LCD TV, and if one of us is to give advice, we have to know that we are talking about the correct model. Oh, yes, of the freeview decoder, too. If freeview a brand or a concept, or perhaps both? I see from google that I can choose from more than a million things to look at information on "freeview," so that is a bit wide of a net to cast!
