Once the input port is chosen on the TV for the Roku usually the Roku remote will take over. Now when you choose the port it goes to the Roku screen saver but the Roku remote doesn't work. It's like the TV and remote are not talking to each other.
@natrajr, if it's a voice remote without a pairing button (it's not a reset button) you can put it into to pairing mode by pressing and holding Home and Back at the same time until the light starts flashing.

Have you tried new batteries in the remote? Is it a simple remote or a voice remote?
Even i have the same issue... I have tried the following:
1. Replacing new batteries
2. Resetting the Roku Express 4K+ device as there is no reset button on the remote.
3. Unplugging and plugging in back both HDMI and Micro USB cables.
Still the same. Can someone help?
