Mine too. Was fine at lunch time but by 2 o'clock it keeps switching on, shows 'welcome' then switches off again. Noticed there were people with the same fault about a year ago and the solution was going into the 'easy setup' on page 101 of the manual but this isn't working on mine. Live TV appears for about a second then freezes and the unit switches off again! Pressing 'System Menu' doesn't do anything. The previous people said it was a faulty firmware update from the bbc. It seems funny that both machines have developed the same fault on the same day. I live in Devon, where are you?
