Yamaha htr-6240 directv codes do not work on rc65rx remote

SOURCE: All Yamaha HTR-6130 codes don't work on DirecTV remote

try 30176 and dont forget to assign the remote to turn up the receiver not the tv

SOURCE: Can't set TV code on Yamaha rav293 remote

i had the same problem with the same remote but just figured it out. on the remote, to the left of the "DOCK" button, you'll see two buttons labeled "[A]" and [B] which is what you'll use as the TV source button. press the code set button, wait for it to blink two times, then press the [A] button, and press your code. VOILA! problem solved. you could also use the [B] button, but it doesn't really matter. now the tv controls work on the remote. you may have to go through all the codes for your manufacturer but eventually it should work
