Advertisements Hello, I'm new here and am hoping someone can help me pinpoint what may be wrong with my Tivo HD. Symptoms: Blocky/pixelated channels, worse on HD channels, low signal strength via diagnostics (varies between 0-44), utterly insane number of RS errors, high-pitched whining noise I had the cable guy come out to check the line, no problems with signal on other devices. My Premiere gets a 93% on that same exact line and plays fine. I also replaced the cable card and hdmi cable, just to rule out possible issues there. It made no difference. As for the whine, it seems to come from the HD, so am currently doing that kickstart HD test on it. Older recorded content plays back fine on the Tivo, however, so it may not necessarily be a HD problem. Some of the capacitors on the power supply look a teensy bit 'puffed up' near the top, but did not notice any blown capacitors on the power supply itself. No clicking sounds or problems starting the Tivo. So, any ideas? I thought maybe due to the RS errors, I would need a line filter/attenuator thingy, but that probably doesn't make a whole lot of sense if the signal strength is coming in at 44%.
