I’ve done all that. I can input two or three codes which will turn off the TV, but pressing OK (as instructed) for 3 seconds only results in two blinks of the red light – it has always only flashed 2 times from the start. The only way I’ve managed to control the TV (on/off and volume) with the Aura remote was when I reformatted the hard drive and started from scratch during which as I vaguely recall there was a key sequence “concerning” the remote. I’m hoping that someone knows that sequence.
