Similar to other Comcast customers posting on this topic, I have recently been unable to successfully troubleshoot a recent "No Signal" issue.  It occurred when I turned on my TV (it was working then) a few days ago.  Intending to watch a DVD, I switched to AV1 to watch my DVD. I could hear sound, but no picture, then the "No Signal" message appeared on the TV.  I switch back to HDMI1, but received "No Signal" there as well.  For the past 3 days, I have been trying the troubleshooting possibilities sugested by others (all cables are correctly connected, replaced HDMI and video/audio cables, etc.).  When I select "auto tune" to see if I have any channels, the result for Channels Found is zero.  What should my next step be?

Please help.

I did not find the right solution from the Internet.
