i got a new Sony Bravia KD-65x9000f once set up i tried to set the time, The Auto time does not work at all.  So i set it manually, And thought all was fine.  Turned the TV on this morning and the time had reset along with the date, So i manually entered the time and date again.  Anyway i was just watching BBCi then came out to go back onto my PC and the screen went black with the Sony Logo then my PC came onto the screen.  After this happened i noticed the Date and Time had once again reset!
