Ha. My channel guide went to "no data available" like others have had. Checked all the supposed areas, internet connnection, zip code ect. I have fast power on because I have remote roku speakers. One post suggested it was a daylight saving thing. Hmm that's exactly about when the smart guide stopped working. Post said clock gone on main menu, ya mines gone too. Went to settings / system / power / system restart. Well dang after restart clocks back and smart menu back. So it's obviously a system/software screwup caused by daylight savings change. Hard to keep up without tv guide/smart menue. Bright side is at least there's a roku community to go to to solve these kinds issues. Thanks folks.
