Iam facing the same problem,can you let me know how is it resolved(if it is)
i have an 18 month old sony bravia that has started turning itself off and then back on again automatically . it does this within 5 to 30 seconds of it being switched on . ive changed the remote batteries , checked the cables , moved the plug to a different wall socket but its still doing it . the tv does not stay on long enough for me to check the settings. i have disconnected all the dvd and sky boxes and it still does it ...has anyone got any ideas ?
