I'm having the same issues with my phillips flat panel. I downloaded the firmware update from phillips and that helped...but only once. I'm back to the same issue this morning. But you might try this download...it may work for you.
1.Check first if the shutdown of your tv follows a certain period of time. Example after using it within 12 hours it automatically shut down. If so the the matter is only on settings of your tv. 2.But if your tv shut down at an irregular time the problem is in your board. In this case if your tv still work but still shutting down automatically its better not to use it so that their will be broader damage. 3.The most common defect on this case is loss contact of components due heat and mechanical undergone during the usage of the tv. If you know how to resolder board, try to resolder the components specially those who are showing loss contact. You can recognize it because a good solder one has shinny and no round like on the soldered surface.Try also to resolder important parts such as IC's and transistors. note : a good resolder needs to be done in order to avoid problems and damage. 4.Another possible cause is the tack switch for channels,menu,power and etc. You can remedy it by spraying it a contact cleaner. 5.If the problem still going even after the procedure its better to bring it on reliable and trusted service center.
TV shutting off automatically means its a problem with the Lamp. Contact Pioneer or any local tech shop or Best buy and get the same replaced. Turning off after specific time : Go to the timer option and disable the Automatically Switch off option. This will resolve the issue. Please let me know if it worked.
