I have 3 of the above sets in my workshop, all from the same hotel with the same fault.
The fault is that although I get a good picture on DTV, I cannot change channel (changes channel ok on analog) also I cannot access the digital menu, everything else seems to work ok (picture and sound menus and scart socket) I am thinking firmware/software, would be very grateful if any body could help. Times are hard and this hotel as quite a number of these sets and therefore could be a nice earner(for a change)
