After trying to resolve a problem with Comcast on the loss of a channel, the HDMI cable hooked to the X1 box fell out. Since that time, my Sony TV has no signal. I have tried all the suggestions and gone through all the box and TV power off requests from Comcast and on my own. No change. I have had no tv picture since Tuesday but can stream from Netflix. This is a smart TV. I purchased a new HDMI cable but there is no change. I have seen all the messages about there being a problem with the HDMI signal getting out of sync. I don't know what else to try and Comcast has not gotten back to me as they said they would on Wednesday afternoon . I called Comcast again Thursday morning and went through all the power off and on checks but no picture. Any ideas on how to solve this problem would be appreciated. I can stream fine . I just can't watch TV channels.
When I asked Comcast that night, I was told to use the HDMI1 port. I just tried the other one after reading your post. It worked. Thank you so much for the suggestion. Before I got the new HDMI cable, my friend tried it but the old cable wouldn't reach. I guess because I had pulled the TV out from the wall so we assumed we had the right port. The new cable is much longer. Thank you again. I spent four days trying to resolve this problem because it made no sense that plugging the cable back in would not fix it. I can now enjoy the weekend! I hope I don't have the original problem again.
