Advertisements Hello. I had to replace a power unit on one of my SD-DVR40 Series 2 Tivos. While doing so, I disconnected the "ribbon" that connects the power unit to the motherboard. When I reconnected the ribbon to the new power unit, the interface of the ribbon had part of its "edge" come off. I think it's a good idea to get some spares for these. Does anyone know what this part is called? It's a ribbon that connects the power unit to the motherboard. Mine says "SCBL-00031-001 Rev A" on it. I tried Googling it but they do not show what this "ribbon" is called.
