XG1v4 requires reboot everyday...

I see this with my box as well.  I just traded in my old non X1 box that performed well for the last 5 years.  My first X1 box was DOA as was the second.  The third box worked.  Every morning I have to reboot the box to get a picture. It isn’t the cable and it isn’t the TV.  I figured out it is after they do the daily updates. Every time Comcast remotely accesses the box for their daily whatever, it bricks the box.  I changed the time from 4 am to 2 pm and when I got home from work today, it was bricked. It follows the daily update time.  It is likely a software issue that is not compatible with the hardware. This should be something they should fix ASAP or there will be a lawsuit against them. It is unreal. I’m going to turn off as many features as I can to see if there is some feature incompatibility during the daily updates that is causing the issue.  I doubt it though.  Probably need a different model box, like maybe my old one, that will fix this. Techs and calls to service won’t get you anywhere. It is a software/hardware compatibility issue thatgot past their quality control testing, if they do any.

There are only two HDMI ports on the XG1v4.  One is labeled "Input".  The other one is labeled "HDMI TV".  Obviously, the TV is connected to the latter.

Huskur, can you please explain in detail what HDMI port did you swap and how.  You apparently have a Vizio TV. Many of the complaints were reported by users who have Samsunk 4K TVs.  The remedy may not be the same with those. Thanks.

I see. The cable is already plugged to HDMI 1.  HDMI 4 only is ARC on my TV.  The cable will be harder to swap because it is builder-installed behind the drywall.  But I will do some testing outside.  Thanks again.

If it is an HDMI issue, then you should be able to unplug and plug back in the cable to bring back the picture.  That would indicate an HDCP handshake issue.    I doubt that is it, but I’ll try it tomorrow when my box bricks again after the daily update.  I also turned off just about every feature on the box that is programmable so will see if that does anything.  If not, I’m taking the box back and getting the non-X1 box.  I have a Vizio TV and my box is X1 but not the 4K box. I am using the same HDMI cable I was using with my old box that had no issues. 

I will be interested in what you find.  I already tried disconnecting the HDMI cable in an attempt to bring the picture back from black screen but it did not help.  I have XG1v4 4K DVR, so that could make a difference indeed.  

Ok, I have done a couple experiments in the last two days with interesting results. I’m honing in on it and will get to a solution but I’m not there yet.

I have the non 4K box. I have HDMI going through a receiver to my TV using ARC HDMI port.  Here is what I did.

1) Disabled every available programmable feature.

Result- Black screen and no picture after daily update

Action 1 - unplugged and plugged back in the HDMI cable.

Result- No change

Action 2- unplugged and plugged back in the RF cable on the back of the box

Result-Picture came back

Conclusion-Box does not have to be rebooted

2) Next day - unplugged HDMI cable before I went to work.  Daily update occurred.

Action 1- Plugged in HDMI cable. Then turned on TV.

Result: No picture. 

Action 2- Unplugged HDMI cable and plugged back in.

Result: Picture came on after a slight delay

Conclusion: Hmmm.  May be an HDMI handshaking issue. Also picture came back after delay, so I’m wondering in day 1 if I didn’t wait long enough

Planned experiments:

Bypass received and go straight to TV with Comcast provided HDMI cable.

After daily update, if no picture, change HDMI port on TV and then switch back. Determine if pic comes back. If so this may be an acceptable compromise. If not, I’ll unplug HDMI and plug back in.  If that fixes it, I may try using a non ARC Port.  Not sure where to go if that doesn’t work. I’ll get my old box back!

Maybe someone else can try some of these to see if they work on the 4K box.  Wonder why they didn’t give me a 4K box!

Their supplied HDMI cable caused error problems for me day 1.  My HDMI cable did not for 22 months.  Yesterday, the box would not start up.  Box reboots and system restores allowed the secondary box which runs off the primary box data to operate, but not the primary.  Code XR-00075 or something.  I could even pull up the guide because my TV is paired to the primary box but could not open any channels. 90 minutes on the phone where they repeated the same trouble shooting efforts I already did resulted in a service call.  Service guy said the system said it wasn't the box but the drop line had experienced issues.  He replaced the line which increased internet speeds but problem persisted. When he realized the box would never activate but that upstairs secondary unit was working, he realized the primary box was not putting out video.  He's been doing this for 15 year and said the  XG1v4 has presented more problems than any other unit.  Moral of the story is if your having to continually reboot, something is probably wrong.

besides your DVR do you have at least one XG2 companion set top box? it can supply tuners and access to the internet for other devices (like wireless xi5/xi6 or the coax connected xi3/xid). that would free up the tuners in your DVR.
