Bose universal remote does not turn tv on/off

Hi,
I set up my Bose Cinemate 520 with sound touch yesterday. I was able to configure the Bose remote to control my Verizon Fios Cable set top box. 
However when I hit the Cable/Sat button the TV LG55" LM 7600 model # does not automatically turn off. It would not turn off when I press Audio button. I have tried CEC auto and alternate as well.
The TV is connected via ARC HDMI port.
Please advice.
Thanks,
B

Hi B,
Assuming you have also programmed your remote to control the TV, (with a code similar to what you did for the Cable box)  Turning the TV off can be done manually by selecting the TV button and then pressing "Source power".  (to the right of the "Audio Power" button).  This function cannot be attached to the Cbl-Sat button as that relates only to Cable box control.
Thank you.
