my ROKU device is now flickering on the video. worked fine this morning, but this afternoon it is doing this. I have unplugged the power and hdmi to it,I have tried other hdmi ports, nothing works. I have confirmed that the HDMI ports are functional with my OPPO (which doesnt do updating). I think this may be an update issue and the latest update tells the ROKU not to like my TVs HDMI ports. Any ideas on how to fix this, other than buying a brand new one.
In desperation, I did a factory reset and forced the device to a 720p interface. for some reason 1080p would not work, it would be all static and flickering. This is interesting because my TV is 1080p. Lets hope another update doesn't cause it to revert back to 1080p and flickering.
