I have a TiVo Premiere TCD746320 that I've had in use for several years and for which I purchased Lifetime service. I'd like to keep it alive if possible. A couple months ago, it died and after rebooting it was stuck on the "Welcome… Starting Up" screen. It would reboot and then go back to that screen. After each of the steps below, the problem persisted. I'm trying to figure out what to do next… Removed M-Card Removed 320GB hard drive and replaced with 4TB WD Red that I imaged with DVRbars and a clean image that I got from a kind person on this forum Replaced Power Supply with part from Weaknees I feel like I've done all the steps that I could reasonably try. I assume that my lifetime service is tied to the logic board and I can't make any other repairs to this device. Anything that I'm missing or should try next?
