Macro question. In the off macro, just put the power command in twice. If your tv needs a slight delay between each press of the power button, you can insert a timer button press between the two power commands. Each press of the timer button will delay the next command about 1 second, and will not do anything else.
1st macro-tv component button, power, amp component, power, stb, power
2nd macro-tv component button, power, timer button if necessary, power button, amp component, power, stb, power, and then press the component button you want to end up on
Volume button problem-If you learned the power command (I don’t know why you would have, but incorrect learning is the only thing I can think of), relearn and be sure to hold the button on the original remote down until the 3000 beeps. If your original remote permits you to rase or lower as long as the button is depressed, the 3000 should also do it.
Your question, and many others which may come up, will be answered somewhere in the following threads.
