Every time I pull up YouTube, it doesn’t show full screen is zoomed in and pixelated and I can’t get it to come up. I’ve tried turning my TV off I’ve tried deleting the app and re-downloading it. I’ve also tried to update it there is no update and I’m trying to see if my TV needs an update in there needs to be new update so I don’t know what’s wrong with my YouTube but I can’t get it to work on my Roku TV now it just started happening.
Try rebooting your router.
How far is your device from the router? How old is your router? What model/brand of router?
After removing the channel, but BEFORE reinstalling it, did you RESTART** your Roku to clear its memory cache? Without the restart you may not get a clean reinstall. This is not a cure-all but at least it will assure you of having an uncorrupted copy of the current channel app.
Depending on your Roku model number you'll find the "System restart" option under either "Settings > System > Power" or under "Settings > System". If you don't have sufficient control to use the menus, or if it is just more convenient, you can also restart by pulling the power plug for a short while, then plugging it back in.
**On a Roku TV with "Fast TV Start" enabled, turning the TV off/on only puts you in/out of a low power standby state, it does NOT give you a complete restart. Use the methods above.
