Since thunderstorm last Wednesday, I have had nothing but a blue screen. Audio over optical works fine and changes as I change channels. But I am not getting any video. Connected via hdmi using redmere cable.
Has been working flawlessly for months. I've rebooted, dis/reconnected power and hdmi, confirmed input. Countless "signals" sent via self serve app, and 2 different comcast techs. One I spoke to on the phone for over an hour, the other I wasted another hour with, via chat. Both assured me "this will definitely fix the issue". It didn't, either time. Both assured me at the end of our sessions, that I would get an email with support ticket info, to follow up. Never got any email either time - that alone is entirely unaccceotable!) Sigh.
Each time I reboot the x1dvr, I initially get a black screen that says "welcome to x1 platform", so I know signal is getting to the display, the hdmi cable is fine, the display is working and set to proper input. But when the boot completes, the screen goes solid blue, but I get audio. And when I shut the x1 off (remove AC) or disconnect hdmi, the screen goes from blue to black, so the blue is definitely coming from the x1, not a default screen on the display.
Anyone have any other suggestions, or ability to confirm the x1 box being the issue? I can't bear to waste any more time with the laughably-lame Comcast support - especially since I seem to be getting blown off, and there's never a ticket issued documenting my previous support follies, so I have to start over each time ("Is your x1 box plugged in to power, sir?" Cmon!
Also note that both times I've contacted "support" I requested escalated or tier2 support from the start, and numerous times during the exchanges, and both reps "talked me out of it" - essentially refused).
Is there any way I can reach anyone at Comcast who is technically /analytically savvy on the issues (rather than clearly following a very weak and rigid support script), can communicate professionally, and has at lease basic grade-school-level mastery of spoken English?
And am I insane to think I can get a tech to bring a new x1dvr to me, rather than me having to waste more of my time driving n standing in line?
Open to suggested next steps.
Thanks in advance gurus!
on your Xfinity remote press the following buttons -- exit exit exit 720
If no picture then power down reboot the cable box.
It's possible during the storm that the hdmi port on the dvr was damaged. Since audio is working it's a safe bet the dvr is ok but you'll need to swap it. Assuming you've tried different devices on the hdmi port of the tv (to rule out the tv's hdmi port) and different hdmi cord.
Signal levels are well within spec. If you can, use a second tv and see if it replicates it or not.
You pressed Exit three times and entered the numbers 720? Why would you even think of doing this and why would this change anything?
It changes the STB output resolution to 720p. Some TV's need that resolution to work with X1.
To help residents and emergency personnel stay connected during this time, Comcast is opening up Xfinity WiFi outdoor and SMB hotspots in these communities to anyone who needs them, including non-Xfinity Internet subscribers.
This will be starting at 4:00 PM ET on Monday, March 5, 2018, through Friday, March 16, 2018.
