I have a Sharp LC-70UD1X
I have had it for a year with no problems.
I moved to Maraetai (Auckland NZ) with the same signals as the Auckland City.
I plugging into the Arial and everything worked fine, picked up all the normal freeview Digital TV channels
etc. However, when I turned the TV off....the next day when I turned it back on, it could not see any DTV channels (said channel wiped on the message), it had completely lost all channels with the exception for Kordia TV (200) which really is just an add.
I can re-install the channels by doing a new search and all is well, until the TV is turned off for a reasonable period of time (if I turn TV off it will keep all the channels when I turn back on after a short period of time), then it completely wipes all channels again with the exception of Kordia TV.
When I have all channels operating correctly and select the Kordia TV channel, it runs the Kordia add thing, but wipes all other channels.
What can I do to fix this please.
