Re: Intermittent Video Issues Affecting Some Customers

Does this solution also work for the following issue: I recently upgraded my DVR box to the 4k version, and just today found that it has an auto-reboot that occurs every night. For the past couple of weeks, every morning when I turn on the TV (which is 1080p), the channel video is shoved off to the right. I can see the channel video, but it is just shoved off to the right, a little less than halfway across the screen, with a black area filling the remaining area on the left of the screen. If I change the channel, to any other channel, the picture resets and fills the screen like it's supposed to. But every morning, the same thing happens, and every morning, I have to change the channel just to make the picture fill the screen again. This has been extremely annoying!

I'm new to Xfininty. I had Direct TV for the last 14 years. My first 2 months with Xfininty have been nothing but intermittent black screens. It doesn't matter if it's DVR, netflix or live TV. Anythiing through the cable box has this problem.

WHEN IS THIS GETTING FIXED??? I'm ready to pay the early cancelation fee and go back to DirectTV

describe your wiring? is the x1 connected directly to your TV? to HDMI 1 or HDMI 2? have you unplugged the HDMI connector ends and press in again feeling and hearing the 'click' as it locks into place?

Mine shows 117.1.1
I did notice that I set the box to 4K the other day and today when I check again it defaulted to 1080p

Re: Intermittent Video Issues Affecting Some Customers

My XG1v4 4K box took the new update to 117.1.1 dated August 6 and I still have the same problems of the box defaulting to 1080p each time I shut the tv off for a period ranging from 15 minutes to overnight.

 

Leaving my 4K capable TV at 1080p still continues to  start with a tv screen that slowly begins with 1-2  flashing thin horizontal line(s) and the longer TV is on, moves into a flashing partial screen, and the longer I watch, the worse it becomes until the flashing is so frequent(sometimes more than once a second)

 

This eventually leaves the TV unwatchable in the default 1080p as ever larger portions of the screen intermittantly flashes. 

 

Changing the resolution to 2160p 4K clears up this issue,  the X1Gv4's menu shows TV is 4K capable and the resolution is available.  It's not an HDMI cable, as using 4K clears up the issue, seems more like HDCP issue. I was running this exact system prior to the June update without this problem.

 

I read on another posting, that since these recent updates, older X1 boxes that supported component video out have been broken as well by recent updates, with a black screen being displayed, and only sound.

Re: Intermittent Video Issues Affecting Some Customers

I've tried this and it's still pixelating.  I've tried to contact Xfinity and all I get is the stupid troubleshooting, I run through troubleshooting and it doesn't fix it and I can't get a person or appointment.  What's the secret?  My nextdoor neighbor is having the same problem!

Re: Intermittent Video Issues Affecting Some Customers

I have the problem mentioned at the end of your post, after a firmware update, I can no longer watch on demand or DVR recorded content over coax out. All live channel content works. Had Xfinity tech out, replaced with brand new HD receiver (same model I had), and no difference. He called manager and I was told to switch my receiver to 720 before watching, tried, it works. Well, it worked... tonight wife tried to watch an on demand and picture disappeared.
I checked and verified box set to 720, then tried watching a weather channel recording from recent hurricane... Black screen. Even at 720p now locks receiver with no output, have to restart it to get anything on my remote 6yo 50" Sony Bravia.... Not acceptable to try watching a recording I recently made and be forced to restart Xfinity new model Arris HD box. 2160p 4K is beautiful. My box worked perfectly a month ago, only possible change is a firmware update now messing up the coax out for any playback of streaming content... Afraid someone decided to block on purpose like I am some bar running movies on boxes all over my bar... wrong, been a residential Xfinity customer as far back as 2013.
Hope they fix soon.

Re: Intermittent Video Issues Affecting Some Customers

I had a tech come out to fix my intermittent video issues.  He came in and showed him and alos told him my neighbor had the same issue which never happens on Netflix.  He went out to the street and said we were on the same port but the amplifier was making a noise it shouldn't.  He called out the crew that works on that and it was fixed with in an hour.  The only way I got help was calling 1-800-266-2278 and I had to google to get the numer.  I told them I have been through all of their  troubleshooting and wasn't going to do it again.

Re: Intermittent Video Issues Affecting Some Customers

Has this been resolved?  I am still getting sound drop-off, picture turning black for a second or two and pixelating.  My X-1 box was swapped out three years ago, so is it time to swap again or will the firmware update solve the problems?

 

Phone support was of no help.  Lots of, "gee, I don't know" and "I guess that might work" answers.

Mine was an amplifier problem at the street.  It was fixed the day the tech came out.  He did have to call out the other techs that handle that part but they had it fixed within an hour.

Re: Intermittent Video Issues Affecting Some Customers

My problem was finally fixed by a technician visting my house. I availed myself of all the remote options, but no solution.  My problem was the line from to my house from the street box. I'll be getting another visit by the crew that can thread it though the underground pipe. It's temporarily above ground.

I have a buried line, so any problem would be at the top of the pole. I guess the squirrels could have been hungry and decided to feed up there, but I have not called for an inspection. Perhaps I will.

Re: Intermittent Video Issues Affecting Some Customers

Ok, lots of moving pieces, so I'm not sure just exactly which one worked or whether all of them needed to be done to solve my intermittent outage issues.  I scheduled a line tech to come out to check the outside wiring.  The tech found no squirrel feasting signs and received acceptable signals both at the pole and at the junction box outside my house.  Thus, the outages were not squirrel, vole, or worm related.  (Remember buried line.)

The tech then checked the connections inside my house and swapped out the amplifier for a current model.  He noticed that I had more than four TVs in the house but only had one DVR box.  He stated that I might have an issue with that many TVs and not enough tuners for viewing or recording so he swapped out a small HD box for a DVR-ish box that has four tuners inside but does not have the clock on the outside.   We then had 8 tuners total - four in each box. Thinking all would be good, he left.

About an hour or so into test viewing on various channels, the problem was still there.  I disconnected the HD box that was attached to the TV we watch the most and went to an Xfinity store and asked for a replacement.  I installed the replacement HD box and power supply and it slowed the problem but we still had the black-outs and sound drops. 

On a whim, since it came with the new HD box anyway, I swapped out the HDMI cable with the new one even though it looked like it had less shielding than the casing of the one we were using.  The wire gauging was the same, so I felt it should be OK.  Low and behold, the problem became resolved and now two days later, we have yet to have any blips or sound drop outs.  Crossing fingers, toes, eyes, and whatever else, we hope the problem is now premanently resolved.

Soooo, was it the amplifier?  Not enough tuners?  Bad HD box?  Bad HDMI cable?  Who knows?  All I know is that the problem has gone away for now.

 

That's our litany.  I hope yours ends as well.

Re: Intermittent Video Issues Affecting Some Customers

This thread says the box issue creating black screen resolved however I upgraded to a new box in August and encountered this issue. Just shelled out $65 to TV repair guy only to be told the TV is working just fine when off the box. Should I swap to another box? Thx.

the normal fix is to pull out the HDMI cord end and reinsert feeling and hearing the 'click' as it locks in. do this on both ends.

Re: Intermittent Video Issues Affecting Some Customers

The "official" resolution does everything but tell us to put rabbit ears back on our TV. I have a 4k UHD tv. I pay for an Xi6 (and an Xi4) to go wireless. The picture freezes and the surround sound channels cut in and out. It is NOT my surround system so don't blame them. My speeds, at times, are 1Mb/sec download! 

Xfinity's data speeds may be to blame for the problem.
