Problem setting up tivo Roamio OTA tcd846000
Can't advance beyond the welcome screen. NOT getting the 4 blinking lights of death. In fact, all I get are the green light at far left, and the green light at center logo, and they stay solid. No other panel lights come on. The screen briefly goes black every 10 minutes or so, which I believe is a reset.
I formatted the original hard drive in NTFS. I swapped to a known good 2.5" drive formatted to NTFS. I tried a different power supply that I have rated for 12v 3a (original is 12v 2a).
Any suggestions on how to proceed? I'm assuming it's not the power brick since that's indicated by all panel lights flashing? A bad mainboard? I'd hate to give up on this, as it has a lifetime subscription attached.
