Mate, if that makes you happy, well that's cool. I just don't quite understand why you will accept that as the fix.
We are at a day and age when regardless of if your TV is on or off, your ps3 will turn on. Hell, I just press the ps button on my ps3 controller and Ps3, receiver and tv all come on together and flick to the appropriate channels. That is the kind of technology you should be expecting in your brand new TV and your brand new PS3. I could not accept "TV just has to be turned off when I turn the ps3 on" or anything like that for an answer. Your TV is retarded, swap it.
