I’ve done all the trouble shooting. Turning it off and on again. Unplugging it. Deleting apps. Reading apps. Reset picture quality. Etc etc. my roku still flickers. Only certain shows. Various times. Doesn’t matter the channel. It just flashes the scenes with a second or two of black in between the picture. Audi is fine. It’s very frustrating and also the fact that I can’t Contact an agent because of “picture quality” and After going through the online prompts to only get a statement that I need to contact the community for this issue. How do I get it fixed? Is it a faulty roku?
