MAJOR ISSUES. My Roku stick has been working perfectly with the same TV for over a year. Suddenly, I turned it on and the menu came up for a second before going to black and staying that way. I can hear the Roku menu noises when I hit buttons on my remote, but can't see what I'm doing, so can't really get to any settings or anything.
I've unplugged everything and re-plugged it in. I tried other HDMI ports. It's not the TV or the ports because other devices work fine in the HDMI ports. The Roku worked fine last night. Nothing has changed, so I don't understand why it's suddenly not working.
I tried the reset button on the Roku. I was able to get part way through setup before it blacked out again.
UPDATE: I found a workaround in another thread. It would seem this is a pretty widespread issue... But this worked for me for now. Hopefully Roku fixes whatever happened with that last update!
