I've done everything documented to try and fix this.
Xfinity sent me a new X2 remote also...not luck.
Power on/off and All power on/off on X2 displays the Smartbar popup instead of powering on/off.
Been through all the resets and all the codes...
TV is an older LG 32LCD.
Everything on remote works except for this. Very frustrating
I chatted with service and they sent me one. But no luck....same issue.
I'm thinking they know it's a problem with some TVs...but aren't willing to fix it.....
