I've had my TV for almost a year now and it's colors are all of a sudden different than what they were. I turned my TV off a few hours ago because I wasn't going to be watching it. I turned it back on about an hour and a half ago and the colors are off. Everything is black blue or red. It's not my internet and cable provider. Just wanting to know what to do. Should I try a reset?
Yep, these things are just little special purpose computers. Like their big brothers sometimes clearing things out by restarting them is all it needs.
You can restart via Roku menu path Settings > System > System restart (Or for Roku TV: Settings > System > Power > System restart - just turning the tv off/on doesn't give a full restart)
If a restart doesn't do it, or if you don't have sufficient control with the remote to navigate the Roku menus, you can also restart by pulling the power plug to the device for a minute or so then plugging it back in.
