Me to for the last 3 days have pulled the power cord then the time came back but the next day the time was gone and also the TV is not automatically checking for updates and then when you check for an update it doesn't show that you checked that day until you unplug the power cord and try again
i have the same problem on two Roku TCL televisions, It started on Sunday. The clock does not appear on the homepage and no channel guide information unless I reset the tv. Resetting is only a temporary fix. If the tv is left off for a while the clock and guide data go away again.
The following are the answer to your questions:
I am able to stream from other channels when the clock is missing: Philo, Netflix, Amazon, Hulu...
If I restart, the clock and data guide reappears initially but then goes away again aftern an extended period of time off.
My zip code is correct. I have also re-entered the zip code several times.
Same for me on both Roku TV's in this home. Seemed to come back after a power off restart, but then disappears again. The TV's are different brands ... one by Sharp, the other by Insignia ... so it's not unique to a particular brand. Tried system update to see if that would help, but no joy.
