Since yesterday the time on the TV schedule keeps changing. When you start the TV the time is correct. Then you go to the schedule and it stays correct for about 5 seconds and then jumps 8 hours or so into the future. I've tried unplugging the device for 5-10 minutes then plugging it back in. Didn't work. I've tried going to settings, then system, then power, then system restart, and it turned off the TV then on. That fixed it once but not again when it happened an hour later. I've tried Home (5 times), Up (once), Rewind (2 times), and Fast Forward (2 times) to clear the cache. Didn't work. We can no longer tell what's on any of the channels because the schedule is anywhere from 5 to 9 hours off. This seems to have all started after the last update yesterday, but don't know if that's the actual cause. Might just be a coincidence. How do we fix this?
