I have a TCD649080 series 2 that is 5 years old with a lifetime subscription. All I get is black screen. No menus, no boot up screen, nothing but orange light for 5 seconds, then the green light. From reading around, it seems my power supply is near death. Option 1- Pay Tivo $149 + $200 to transfer the subscription. Option 2- Mail it to a website for repair, $149. Option 3- Buy a USED PSU on eBay for $15 While option 3 seems like the choice, I will be left with a 5 year old Tivo. If the fan goes next year, etc, etc.... Wouldn't it make more sense to just buy a brand new TCD649080 on eBay for $50 and put my old motherboard into a brand new Tivo? Is there anything wrong with this logic? Is there anything I need to know other than the excellent photos and instruction I found at iFixit for the TCD540080? Thanks in advance for any answers!
