Yesterday I was moving my TiVo around and grabbed the case from the front, wrapping my fingers underneath on the right hand side and discovered that there is an active current running through the thing. In the past I had associated the current and subsequent shock to power running in the cable line itself, but when I touched the cable connectors I didn't feel anything. Several times I touched the TiVo while sliding it around to remove the HDMI cable and each time I touched a spot on the chassis that delivered the shock. What gives? is this current coming in from the cable line, or do I have defective TiVo? It's done this from day one since I first discovered the shock when setting up cable cards and a tuning adapter a few years ago. This THD is unmodded so I know it doesn't have any loose parts I left laying around in it that might be causing it. Ideas? What are my options with TiVo? It's way out of warranty.
