XG1v4 4k DVR no signal to TV blue screen
Works fine until I switch HDMI input to other source like Xbox or Blu-ray then when I switch back to XG1v4 the TV displays a blue screen. I have to manually disconnect the HDMI cable from the back of the XG1v4 and plug it back in to watch my TV shows. I believe this is being caused by a failed HDCP "handshake" between the XG1v4 and my Samsung KS8500. Since this started happening only after upgrading from the old X1 DVR to the new XG1v4, I have to blame the newest component. I read another post on blue screen issues and laughed when the "service expert" suggested a short with the TV. Please don't insult me like that. And yes, I've already disconnected power and coaxial cable and waited 5 minutes and reconnected and It still does it. I swapped HDMI cords to a high quality cable, and tried different HDMI inputs on the TV. I don't think I should have to "trick" the XG1v4 to re-establish signal with my TV by pulling the HDMI cable every time it blue screens.
What's the solution?

Yes, this is exactly what we are experiencing. Interestingly, I was originally led to believe this was a Samsung/Comcast issue. Definitely a Comcast issue now. Others have Sony sets and now your Vizio. Keep checking back on this thread. This problem has not been solved for over six months.

All,
I seem to have found the cause of my issue. Since I've made the change I have not encountered the problem again.
I actually worked with a few different Comcast service reps (they were very knowledgeable/helpful!) - started by troubleshooting with settings on the box and settings on the TV. Ultimately in an earlier post/thread I remember seeing the HDMI link option (that had been on Comcast Labs) worked for one person but that was removed from options.
Searching options on my TV I found the CEC was turned on. There are probably more technical people on this thread that can explain better but since that was on it was causing my issue. More on CEC: http://encyclopedia2.thefreedictionary.com/hdmi+cec
Once I turned the CEC option off on my TV, I have not had the problem since!
I'm not sure for Samsung/Sony if the option would use the same term as Vizio, but I would suggest searching your TV settings for this to turn it off - reading that CEC still has some kinks across vendor products.

Unfortunately this did not work for me. I’ve got a Samsung TV and the setting for CEC was off. Still get the blue screen whenever I turn on the TV after it’s been off for a while. Same issue for over six months now. Fingers crossed for a fix, or for Dish to buy Comcast!

Tvguy2 -- Thank you for reaching out to us in the Forums and I apologize for the issues you are having. Were you able to swap your box out as suggested?

@ComcastLeon Would you still like my TV/Box info or have you given up on this issue?

So is Comcast/Xfinty in the habit of deleting posts now?

Issue with Sony TV, as well. Not a blue screen. Black screen. No sound. Nothing. Unplugging and replugging the hdmi cable is the only thing that works. HDMI cable was perfectly fine with directv. I can see from researching this forum that this problem has been ongoing for years, and comcast's continued response is that it must be a problem with their customer's equipment. Apparently the only solution is to put up with it until my contract expires, then return to satellite.

This solution may be Samsung specific but the only way I have been able to resolve the blue screen failure issue is to turn off HDMI UHD Color on all ports. Turning it off only on the port connected the XG1v4 box did not resolve the issue. This could be due to the single port connection from the multi-port one connect box to the TV.

Decided to give them one last try. They replaced the 'new' box, evidently designed for 4k tv's (I have a smart tv but not a 4k), with one of the previous models (the one with a clock on the front). No more problems. It has been over a week now, and the tv turns on perfectly every time.

I am having the same issue as the others here, we have the X1 DVR Box and have had it reset a multitude of times but are still getting the blue screen on our TV. I have called into customer support and both times they told me that we needed to switch to a coax cable because our TV is no longer able to support the high bandwidth of the box (this seems strange being that we have had no issues in the 8 months we have been customers and it was working this morning).
What do we do now? We do not have a coax cable, I do not want to go buy something for a service that I already pay $180 a month for, and our TV is only a couple of years old and high quality (Samsung) so that should not be the issue.

I just went to the new X1/4K box and am having the same issue. It first started with me when I went to HDMI 2 for 4K Apple TV. It doesn’t happen all the time, so I’m trying to pinpoint when it happens. So here’s my question, do I really need the Xfinity 4K box since nothing is broadcast in 4K. I don’t use the apps on my Samsung 4K UHD nor do I use Netflix, You Tube, etc through Xfinity. I use my 4K Apple TV for all that. So, am I better off going back to the “old” box?
