I’ve noticed on one of our TVs that the picture is a little blurry or something slightly off… more noticeable while watching sports. I’ve unplugged and plugged back in the Roku stick and that didn’t do anything. Played with the settings and that didn’t help either. I’m sure it’s the Roku because when using the smart tv app for YTTV the same game looks great, but when using the Roku it’s not. So, do these sticks wear out over time? I will say that a few times over the past year a warning saying the device is overheating pops up and it does feel pretty warm. Thought about replacing with a Roku box… but I don’t think YTTV would be available on new device. Any experts who’d know about this?
