I have just bought a 22" Bush LED TV for my bedroom (BLED22FHDL8), however I do not plan on watching television on it as I have only bought it to play games on and watch DVDs etc, but every time I turn it on it tries to automatically tune itself which is rather annoying since I have to exit several menu screens before I can start using my TV. Is there any way I can turn this function off?

This doesn't sound like a "function" of the TV. What menus are you exiting each time the TV starts up? Is it acting like it is the first time it is being turned on? For example, is it running a "first time setup"?

If it does this all the time, when you shut it off, are you unplugging it or turning off a power strip? Or is it connected to a "green power" power strip? Some of these power strips will have a master plugin, and let's say you plug a lamp into that master plugin, the strip will not allow any power at all to be used by any of the other plugins unless your lamp is turned on. So make sure your TV is plugged into that master plugin spot.
