This all started after an up date a week or so ago.
Hit mute, volume up, guide, change channel, pause, rewind, etc it lags and takes 5 or so seconds to respond.
Thanks for the post.
Have you already tried replacing the batteries in your remote to see if that helps the issue you are seeing?
Please keep us posted what you find out.
Thanks,
Danny
That's the first thing I tried. It didn't help.
These things are just little special purpose computers. Like their big brothers sometimes clearing things out by restarting them is all it needs.
Restart via Settings > System > System restart (Or for Roku TV: Settings > System > Power > System restart)
If a restart doesn't do it, try pulling the power plug to the device for a minute or so then plugging it back in.
Let us know how you make out.
