The signals sent by the Harmony Hub are IP, not RF or IR. One of the problems is the navigation buttons don't work reliably when trying to navigate on the main screen of the Sony KD-65X85K television.
In case anyone is looking for the same solution, it turns out that Logitech has since updated the device file for the Sony KD-65X85K television. Now the navigation buttons work perfectly but the power on commands don't work reliably. Perhaps they'll eventually fix this, too.
Meanwhile Logitech support proposed this simple fix. Using MyHarmony, just add the device Sony XR-65A90J to your account. MyHarmony will search for the Sony XR-65A90J on your home network but won't be able to find it. Simply click on "Done" and you will have added the device. Then replace the KD-65X85K device in your activities with the Sony XR-65A90J device. You will now be able to control your TV with reliable IR signals.
I wish I would have done this a year ago, but at that time Logitech support was unable to help me. Now it's a year later and things have changed. It appears Logitech is trying really hard to support the Harmony remote, even though they stopped making it. I guess they are concerned with brand loyalty. I was ready to give up on Logitech and never buy another one of their products unless I had to. Now my attitude is reversed, and I commend them for their support.
