I have three Roku devices attached to my Vizio TVs. I bought the first two Roku Express 4K + in August and have no problem with them. Every once in a while I get a message that says "Roku is having trouble playing this content. Not sure what that is about but I hit OK and the program continues. In October I bought another Roku Express 4K+ and placed on the TV in our Game/Family room. This is the one that gives me error code 020. I can watch for a long while and it suddenly appears. I have unplugged, shut down, pugged into the wall outlet, moved to another HDMI port on the TV all to no avail! I see many complaints about this but so far no real fix. Anyone?
I've seen plenty of complaints over the years without any one solution. Can you try shuffling things around to see if the problem stays with the Roku device or the TV or a particular cable or power adapter?
