Remote not turning the tv off

Hello RID. Thank you for being a Cox Customer. I certainly apologize for the remote issue you are experiencing. I can understand how frustrating that can be. In these instances, the main codes can override each other, in which you may need to set one or the other manually. I would suggest programming the audio receiver first with the on screen assistance as you have done, then program the TV manually after. To program the TV manually, you would hold the SETUP button down until the LED light on the top goes from red to green, then you would press 12051. See if that keeps the programming for both. If not, repeat the steps and use the following codes to see which one will work. 12280, 12281, 10766, 10814, 10032, 10060, 10178, 10408, 10482, 11597, 11959, 10812, 11632, 10702, 11454, 12253, 11903, 11060, 10587, 10217, 10329, 10030, 10650, 12284, 10056, 10090, 10427, 11575, 13118, 12278, 11581. Please let us know if that works. 

The second recommendation worked with the first code, 30176.  Power button works on both and volume works for the Yahama audio receiver. Thank you.
