XG1v4 requires reboot everyday...

Yes, that is correct.  But I don't understand why your xg1v4 is sending PCM when it is capable of dolby digital.  Or why it would select that on auto if your TV is capable of accepting DD.  That's why I wondered if it would see the DD capability if you plugged it into your receiver.  When you are testing, be sure you are using a source that sends surround (maybe the netflix or amazon apps where the content is marked), although mine seems to send everything as DD even if there are only 2 channels.

The Netflix app and content should be the same if you run it on the X1 box.   Have you checked if there is a firmware update for your TV.  Some other (different) LG issues posted here were resolved with an update.

If the Netflix and Amazon apps on the X1 box send DD 5.1 the settings have to be right.  Mine (on auto setting) seems to send everything converted to DD.

The problem returned about 2 weeks ago. And then there was a restart or reconfiguration in my service area, where I had to restart my other boxes. And the problem with the x1 went away. Weird.

I am the original poster for this. Somehow, an "answer" was selected for this that was NOT a real answer (and it wasn't selected by me). So, let me provide an update.

 

My issue began in July 2018. After countless attempts to resolve this issue, multiple XG1v4 replacements, many phone calls, a few tech workers sent to our home, changing settings on the TV or X1 device, etc., nothing worked.

 

By October 2019 (literally 15 months after the problem was first noticed -- and more than 450 days of having to unplug and replug my XG1v4 box to reboot it -- I had given up hope. I was going to transfer my home phone line from Comcast to AT&T and simply cancel my Comcast Xfinity service altogether (after 11 years with Comcast).

 

As my one-year locked Xfinity pricing was about to end,  something changed. Suddenly (in October), there was an outage. Afterward, I could turn on my TV with the remote and it actually worked. I had little faith that it would last more than a day or two -- but it did. A few weeks later, it still worked. It felt like a miracle. My cable would actually work when I turned it on!

 

It is now mid-November and I have not had this problem for about a month. The only thing that I can conclude is that it was some sort of software issue that was FINALLY resolved. It wasn't a tech support person fixing this via the phone. It wasn't a tech sent to my home. It wasn't a setting on my TV or X1 box. It simply started working.

 

It is crazy to think back over the last 16 months and how I had to unplug and replug my TV in every single day throughout that time period. To compensate me for my inconvenience, I had been promised credits a few times. They never showed up on my account. I had been promised that my issue would be escalated and I would receive a call. No one ever called back. 

 

In fact, I think that I only actually received one $20 for the "inconvenience" (of being unable to use my cable each day without having to unplug and replug my box in everyday). I don't think that I ever felt less valued as a customer than I did throughout that time. I think that Ken (the Xfinity rep in this thread) was the only one that seemed to go out of his way to find a solution. 

 

Still, it is nice to know that this issue has been resolved for me. I don't know HOW it was resolved after 16 months. However, it was resolved nonetheless. 

 

If you're still experiencing the problem, I would suggest that you contact Xfinity Tech Support and refer them to this thread. Whatever they did for me (and others like me) needs to be done for you.

How do I order an outage?  Ever since we moved to our new house, I've had to occassionally reboot an X1 box in the same room.  The setup in the room hasn't changed since we moved in:  Cable wire into X1 4k box...HDMI to Pioneer Elite receiver...Receiver HDMI out to LG OLED TV HDMI in (not ARC).  TV not on on power save/eco settings.  When not in use, TV and receiver are turned off.  X1 4k box had always beeen on power save mode.  We have another 4k X1 box running through a Yamaha receiver into an LG and a non-4k, non-DVR X1 box straight into a Samsung TV....both have had no issues.

The week before Thanksgiving the cable wouldn't come on after several unplugging/plugging attempts.  Would occassionally see the "welcome" screen and then black screen on the TV (which meant that the TV was receiving a signal...when the TV doesn't have any signal it displays a message to that effect).  Reciever was still passing signals to TV because output from the the Blue-ray player through the reciver to the TV worked, as did the receiver's menu.  Swapped HDMI cable from X1 to reciever but still nothing.  Called Comcast and tech came out.  Checked all cables and signal strengths and said everything was fine...good signal from the passive splitter to the X1, etc.  He ended up installing a new (refurbished) box.   During setup of the new box, the tech had to use his portable TV to set up the new box b/c it didn't send signals through the receiver to my LG (in retrospect, that wasn't a good sign).  However once set up, he switched the HDMI cable from his TV to the reciever and all was well.  No problems until last week (Dec. 8th).

Last Sunday, the same problem occurred.  Lather, rinse, and repeat re: testing all inputs, etc.  Another tech came and this time he swapped out the power supply.  He was able to set up the 2nd box without having to use his portable TV so he attributed the previous incident to the power supply.

This morning, the same issue...no cable.  Tried this time to switch the HDMI from the receiver to go to the TV's HDMI 2 (ARC) connection...still nothing.  Then found this thread.  A third tech will come tomorrow with a non-4k, non-DVR X1 box...will see if that works.  (WHile the LG is 4k capable, the Pioneer is too old to pass 4k signals so it won't be a big loss.)  Perhaps the problem will go away.  Or perhaps someone can let me know how I can order an outage in the Boston suburbs?

That's not the normal experience.  If disconnecting the HDMI and reconnecting wakes it up, it is the handshake with the TV failing which seems to happen with a few brands/models.  Switching TV inputs to a different port and back might be enough to wake it up.  Some people have fixed it by changing the low power/sleep modes of the box and/or TV, updating TV firmware, changing the HDMI cable, or swapping the X1 box.

Twice I haad the problem, and twice it was resolved after an area-wide Comcast reset. Not a software version on the box, not a software upgrade to the TV, but a reset area-wide. Maybe it's a signal strength issue, or something, but it's working now.

I have remarked this post as your Best Answer. You deserve it.

This post will be "Locked" since solved for you.

Thank you.
