This Sony LED tv required that I leave it in the off position in order to have the firmware software update. It was unbelieveable to me that I would be expected to leave my TV off for 24-36 hrs in order to get the updates necessary to use the online applications. The printed and online manual is very poorly written and inadequate. No explanation of lights on front display and the layout of the input output jax are poorly described in the manual. Registration instructions conflict between online & enclosed.
