My original 3TB Bolt fell victim to the flashing lights failure back in late November. Tivo replaced it with an identical 3TB Bolt for about $80. I thought everything would be good for a few years until the new 3TB drive failed. Starting a couple of weeks ago I started having the problem described in the subject line. About once a week, if watching the Bolt at the time, I'd get a multi-color screen flash and then all black. The green power light and red recording light (if recording) stayed on but absolute no response from any remote button activity. The only fix was to pull the plug and reboot. If I wasn't watching at the time, then when I turned the TV on all I'd get was the black screen and unresponsive remote. The Bolt was in the same cabinet all my Tivos, including the original Bolt, for many years. I am having the same problem even sitting out in the open in a fairly cool house. The problem is starting to happen more than once per day. Anyone else having the problem and/or anyone have a suggestion as to what the problem could be? Thanks in advance. Edit: I swapped out the power supply and the problem continues.
