Well, I can't personally say that they do, but I am pretty sure that Roku does not manufacture its own TVs and that it is dependent on what manufacture they use to make them. When a TV costs only a couple hundred dollars of any brand, they are either very old models, basic ones or new models with components whose quality is questionable. You may get one to last a long time and you may get one that will last a week, that is usually the downside to cheaper TVs. There are only about 5 manufacturers of the screens, but it is usually the other components like the control board that tend to be problems, due to the widely varying quality of the parts.
