Hi Gang. It's been a couple of years, but my Cablecards are acting up again. Both of my Series 3's are getting the "searching for signal" and gray screen on one or both tuners. Already trekked to the Comcast store and got two new cards for TiVo 1 and only one of them works, NOW TiVo 2 is acting up. Not sure if it's part of the same problem or if the CSR at Comcast messed it up when she was trying to fix my other TiVo. So now I have TWO hosed TiVos. Not sure what else to do except wait for the Truck Roll today. I'll keep you posted. FWIW my signal levels are at about 95 on average and my Signal to Noise Ratio is at 35 dB (is that too low?). Any thoughts on what might be going on?
