Hi, we have Zinwell box and a Hitachi TV which has given us no problems to date. Yesterday our daughter swears she only tried to turn the tv off using the tv remote, however has managed to lose freeview all together. The freeview is also used to mirror tv in our bedroom,  and it works fine in there. We have tried turning everything  off and retuning (direct option as opposed to position on tv) however just same black and white fuzzy screen. Cannot see the freeview box menu at all on the TV.  The tv HDMI cable and other AVs work fine on the TV. Any helpful suggestions welcome. Will probably have to get someone in!,
