My roku premiere has never had a problem until a few days ago. It actually startles me when it happens. I'd be watching a movie and then the screen would suddenly crash for a split second or two, and then go back to normal. When it happens, it makes a static noise and the screen goes black, and then it goes back to normal about 2 seconds later. Its been happening about every few hours or so. I've tried changing the #hdmi inputs on tv, #reboot, tv power cord wall change, unplugged the roku, ect. This has never happened before this last new software update.
Some people say changing the roku display settings to #720p works. So i will try this and see what happens. I also see lots of people has been having this same problem. Glad its not just me. Roku needs to fix this bug with a new update asap!!!
