I have 2 Lifetime Tivo HDs that have worked on the same TVs and HDMI cables for almost 5 years without a problem until recently. One of them simply stopped outputting anything after the Tivo "Welcome.." screen. When the boot-up process advances to the "Almost There.." screen, the HDMI output signal simply goes off but the AV and Component signals keep working. Everything else works normally after that (except the HDMI signal). The System Status screen says HDMI is “not connected”.

I’ve swapped my two Tivos between rooms (every combination of TVs cables, etc) and the problem is clearly only with one of my Tivos. I inspected the HDMI connector physically outside and inside on the PC board and it looks good. Also, if it matters, I'm not using cable cards. I use only OTA and analog cable inputs on both.

Since the Welcome screen displays properly every time, it seems like the HDMI hardware must be working and it seems like a software or HDMI handshake problem.

I’ve searched several forums and saw other folks reporting similar problems but I didn’t find any solutions or explanations. I'm stumped - Any advice would be greatly appreciated.
