Hi, I have a VERY old Tivo Series2 with lifetime, that finally died. Wouldn't get past the starting up screen. I assumed a bad hard drive so I used MFSTools and restored a backup to another drive. This got as far as the Tivo animation screen, then video cut out and it will only boot if it's unplugged for a while, but never past the 'Almost There...' screen. Any suggestions for next troubleshooting? Any chance its the power supply? Not sure what else to check. Thanks!
