Signa S4 Soundbar HDMI control

My S4 does not respond to Sony Bravia TV remote. The TV is a recent model KD-50XB5J. I was using the same setup with a Klipsch Bar48 no problem. I went through the unplug everything, used the same HDMI, tried a second S4, and reset the setup in the Sony.

Polk of course said the problem is in the Sony TV well it worked fine with another bar.

It is not a debilitating problem just inconvenient. Anyone have any experience with this?

Thanks!
