Why does my TV stays on rebooting/ welcoming loading screen?

Mine was doing this and 2 Cox techs said the DVR was failing which turned out to be correct.  It would only do this after the Daily Update (someone called it a refresh update) or if the DVR was unplugged then plugged back it.  The incoming signal to the DVR was strong and clear.  Apparently whatever device in the DVR that tries to connect to the Contour system fails, which causes it to keep retrying.  Just for fun I experimented with rearranging the splitters, putting an attenuator on the DVR, and keeping a log of everything that happened on the DVR and TV during the rebooting process.  For 7 weeks it would take from 1 to 7 hours for it to stop rebooting and have the DVR come on.  I changed the daily update schedule to run between 8:00-10:00AM which allows it to be skipped.  On the day it failed, it had been rebooting for 16 hours when the DVR showed some status codes and the clock came on which happens just before the flashing 3 dots appear on the TV before the DVR comes back on.  The 3 dots never appeared and 4 minutes later the DVR rebooted.  Four days later it was still in a coma and has now met its maker.  RIP.

The rebooting process was occasionally causing one or two recordings to disappear.  They never disappeared at other times.  If recordings were scheduled or in-process during the rebooting, they would initially appear on the list of recordings when the DVR came back on but would bring up error messages if attempted to watch them.  If left alone they would disappear after 15 minutes, and sometimes an older recording would also have disappeared.  If there weren't any recordings scheduled or in-process during the rebooting, an older recording would sometimes have disappeared 45 minutes after the DVR came back on

My replacement DVR has worked for 16 hours.  I skipped the daily update 🤪.
