I got that message today (2/2/2020) on my refurbished Bolt Vox that Tivo sent at the end of Nov. of last year. It replaced a Bolt box that had a bad hdmi port. The message also said that the box was trying to fix the problem and it could take up to 3 hours, if that was not successful to call Tivo support. It has been over 10 hours and it is still not fixed. If it is the hard drive and tivo wants to charge me another $84.53(that includes tax), I will replace the drive myself. Will the hard drive from a Tivo Elite box fit in the Bolt? If not what is the price for a 500 gb. hard drive that works in a Bolt? Will the cable card bracket from the Bolt fit in a Roamio OTA? Update Last Thursday I called Tivo and told them about my problem and in about 5 min. they said that they would replace the box for free. It arrived Monday afternoon and every thing is working so far.
