I'm wondering if anyone has successfully programmed the AUX key to control a Sony 2400ES A/V Receiver. I've tried the same process successfully used to control my former receiver; but none of the codes listed in the 622 Manual work. I also tried to scan the bank of codes; but, again none seems to work. I depressed the AUX botton, hit 2, the star key, the power button and then the down key until the list was complete and I received 8 flashes. Any ideas would be gratefully received.
