On another note... to more easily access the back door menu, I programmed a universal remote to rapidly execute the button sequence. You must execute the presses quickly... so quick that it can be difficult to do. I programmed the codes with a .1 sec delay between each code. It did not work with a .3 sec delay. Also, if you have an HDMI source plugged into the TV I recommend switching over to the TV input before attempting this because when the TV powers up, the HDMI chatter interrupts the back door menu process and kicks you out of it.
