Advertisements Ok...after getting the Premiere in February and dealing with little to no signal on my digital and hd channels we finally got the problem fixed by Comcast running RG11 cable. This worked wonders but now we have a new problem. 3 times in the last 3 weeks I've turned on our Sony Bravia and have a black screen with a message saying there is no signal on that HDMI port. One time the signal went out while I watching TV. Unplugging the HDMI cable and plugging back in does not work. Switching to a different port does not help. Switching cables does not help. The only way to get the signal back is to reboot the Tivo. Since the signal from Comcast is not the problem, this makes me think this is a Tivo issue and not the HDMI cable or TV. Anyone else having this problem?
