A:Answer The answer in the owner's manual from Sony is YES. They give advice on how to best avoid this issue, but it can occur. After a set amount of time, as little as 5 minutes, the TV will begin a screen saver function, to help prevent burn in. You can also program a sleep or auto off feature; sleep can be set as to as low as 30 minutes, auto off in as low as 15 as part of the Eco power settings function.
I own this exact model, so all of the functions and times I've listed are exact; I made sure to access all these menus while I was typing this response, just to make sure I was giving you all accurate info.
