I was given the Gallery 15 model as a present in 2008. It has worked fine up until last week when one morning I noticed it was just flashing the brand name over and over. I can't get the pictures to show now. There was no physical damage done to it. It was on the shelf as always, and I usually set it to turn off at 12.30am and turn on at 5.30am. When I got up at six am it was behaving as described above. Please can you suggest what might be wrong with it and if it can be repaired. Thank you. Therese Doyle.
