I replaced a tv with bigger one recently. However my UVerse remote does not turn it on. Only remote for Roku tv works. It takes me several steps to get the tv on. Pressing power button on Roku remote turns on, scroll to the right for the cable image, press enter. They I have the pre screen for uverse and I have to press ok on my uverse remote to get tv. How do I just turn on the tv with the uverse remote??
