Just got a Yamaha RX-V481 A/V receiver. Can't find a remote code so my M7820 remote can control it. 1276 turns it off but not on. Have tried 0176 1176 0354 1810 0133 1331 0186 1375 and 1809. 991 procedure does nothing.
Have you tried searching for the code? If you have tried this step and it's still not working, you can try to swap the remote for a newer model. The new model has 2061 as the programming code for the Yamaha.
