XG1v4 requires reboot everyday...

[chrismireya]

After a recent move, we upgraded from our old X1 box to the new 4K "XG1v4-A" box to work with our Samsung 4K UHD television.

We immediately realized that our box was requiring a reboot every day. So, we've been unplugging the box and plugging it back in. I've contact Xfinity about this issue several times. No one over the phone has been able to help.

Xfinity tech support simply had me swap out my box for a new one (which they have to send via FedEx -- requiring me to drop off the old box to the Xfinity store).  This is the third box and I still have the same issue. 

So, Xfinity sent out a tech yesterday. We were also having some internet connectivity problems (intermittent loss of internet on all of our devices). He discovered that the splice was installed by the Xfinity installation guy incorrectly (or so he said). 

However, the tech was puzzled. He said that everything should be working. He then attempted to say that our "problem" was our television.

I explained that we have swapped to another TV that worked perfectly fine (trading my sister-in-law's for a few days). Our television worked perfectly fine at her house with Xfinity and her TV worked fine at our house using the same box and same HDMI cable.

I explained to the tech that this didn't happen with the old X1 box. It doesn't happen with anything else connected to the TV (e.g., Xbox One, Blu-ray, etc.). I've even swapped HDMI cords, switched HDMI inputs, etc. Each and every time, the problem is only with the new XG1v4 box. 

The tech then said that he thinks that the cable issue that he "fixed" might solve the issue. He left roughly 25 minutes after arriving and said that he would have someone follow-up with me in a couple of days.

Today, I turned everything on again....and have the same problem. 

My TV is a Samsung 4K UHD television.

My power save mode is OFF.

My HDMI cable is 2.0 compatible (and I've tried FIVE of them -- all with the same issue).

My TV's firmware is up-to-date.

Apparently, this is a known issue. There are quite a few threads on the Xfinity forums with many posters addressing this issue. For instance:

Doe anyone have a resolution?

How about trying a HDMI 2.2 cable?  Does the TV have an HDMI 2.2 port?

[chrismireya]

The TV is HDCP 2.2 compliant (if that is what you mean). I've used a Monster cable that is specifically for 4K as well as the cables that came with the 4K boxes that were sent directly from Xfinity. I went to the Xfinity store and they provided me with yet another new cable that they said should work (but it didn't). 

I woke up this morning being forced to unplug and replug the box...again.

I'm largely frustrated that Xfinity knew what my problem was but sent a tech who didn't seem to care enough to say that it was anything other than my television. He kept wanting me to prove that my TV was 4K -- despite the "UHD" posted on the stand as well as behind the television.

I have two XG1v4 boxes and I've never had this issue.  Did you try a tech visit?

[chrismireya]

Yes, the tech visited. I even demonstrated the problem (turning on the TV with no picture). He didn't seem to even care about trying to find the cause. He tried to insinuate that the problem was broken HDMI connections on my TV.

I explained that everything else (e.g., Xbox One, Roku, Blu-ray player, etc.) works in each of the HDMI connections on that Samsung 4K UHD TV.

I explained that another Samsung 4K TV had the SAME ISSUE here but that my TV worked flawlessly at someone else's house (albeit with Direct TV).

I explained that I've tried multiple HDMI cables and none of them work.

This issue seems to be widespread because there are plenty of articles on Xfinity's forums about this same issue. Yet, there hasn't been any sort of solution.

[MNtundraRET]

As already stated; you should be using 4K HDMI cables that are 2.2 compliant. Not all 4K HDMI are created equal. Your first post stated your's are only 2.0 compliant.

[chrismireya]

Are you saying that the cables sent by Xfinity with the 4K XG1v4 box and Monster cables that are marked specifically for "4K ready" arent' 2.2 compliant? My TV is certainly 2.2 compliant. 

[chrismireya]

UPDATE:

There is still no resolution despite the following attempts:

1.) I bought yet another set of HDMI cables (per these recommendations) that are specifically marketed as "HDMI 2.0" and "2.2 compliant" and meant for 4K televisions. The issue persists. 

2.) I tried changing my box's settings down to 1080p and 1080i. Neither solution worked. 

So, I continue having to reboot my XG1v4 Xfinity 4K box every single day. Oddly enough, the phone techs haven't suggested replacing my box with an older box (which obviously worked without issue before).

It would be interesting to see if the old box had the same issue.  Is there any reason you want the 4k box?  I don't need to watch Netflix in 4k so I only use my 4k box for the bluetooth headphone support.

[chrismireya]

We traded televisions with my sister-in-law recently just to check. They have an old Xfinity X1 set top box w/DVR and it worked perfectly with no issues. 

I guess that I will simply have to go and swap out boxes...again. I had hoped that Xfinity would have figured this out. 

On a strangely related note: Since moving to our new home, we have been getting extraordinarily fast internet speeds. We have the 400 Mbps tier. However, we have been easily hitting over 1 Gbps (and sometimes faster). I've used several tests to confirm it. Once, I even hit 3.5 Gbps (which I didn't think was possible) as measured by fast.com. 

That wouldn't be a contributing factor or symptom, would it?

You are correct; it is not possible to get speeds like that unless you have the right modem.  Do you have the XB6?  In the Houston market, they upgraded the 250 tier to 400.  It shows up in the My Account website now.

[chrismireya]

Yes, I have the XB6. I live in the Silicon Valley (Palo Alto). 

The cable coming into the house is connected to a splitter. From there, one cable goes to the XB6 gateway. The other cable goes directly to my XG1v4 set-top box. 

We were having issues with the internet too. Our Wifi was intermittent and my desktop (which is directly plugged into the XB6) would periodically show no internet. After the tech installed the splitter, we've had a few issues. However, Comcast attributed these issues to local outages. 

Interestingly, I didn't have to unplug the XG1v4 yesterday. However, some of the X1 apps (e.g., Netflix app, etc.) didn't work at all until I rebooted the XG1v4.

Sounds like and issue with Internet as a guess.  You can try calling 1800comcast (Internet) and you can try posting in the Home Network forum about your Internet issue.

[Bluesteel2]

Do not have a resolution, just the same problem

Tried anything I can think off, including getting a new XG1v4.  First XG1v$ box a few months ago. Changed back to older X1 due to the reboot issue. Old X1 worked great (until a power surge killed it). Just last week I got another XG1v4. Every morning I have to do a reboot. Disabled power save feature. Set the box to 1080 rather than 2160.

I can see on my Emotiva AV receiver that the box puts out a 1080/60 signal (black screen) with no sound (0 bits).  Every cable, every piece of electronic, are to the latest 4k HDCP2.2 standards.

I guess I have to swap it out for the older box again...

This must be an issue Comcast is aware off. However, nothing is communicated to the techies nor users...

Frustrating!

[chrismireya]

Yeah. This is exceptionally frustrating. I am frustrated that a tech support worker was sent to simply tell me that he has no idea why it doesn't work. He wanted to leave ten minutes after arriving until I explained the issues with intermittent internet too.

A few minutes later, he replaced the splitter (with the older one that splits into three) and told me that they would call back to check on whether my TV and internet was still having problems. He then left. No one ever called back. 

[chrismireya]

Does anyone have a recommendation on how to deal with Xfinity to try and resolve this?

I have two 4k DVR's and neither of them need a reboot EVERY day.  All X1 devices reboot overnight.  You may want to call 800-Comcast and select TV. ask the agent to run the internal troubleshooting guide (einstein) and let it test your line.

"I have two 4k DVR's and neither of them need a reboot EVERY day. All X1 devices reboot overnight. You may want to call 800-Comcast and select TV. ask the agent to run the internal troubleshooting guide (einstein) and let it test your line."

I've had THREE of these 4k DVR's sent to me by Comcast. Both require a reboot every day. I suspect that they probably reboot overnight (but I haven't been up to actually witness this).

I've called Comcast/Xfinity on numerous occasions. When it isn't working and they test the line, they can't detect a signal with the box. When it is working (after I reboot it) and they test the line, the signal seems perfectly fine.

Phone tech support ultimately want to send out a tech. In fact, they did send out a tech who wanted to leave within 15 minutes. He admitted that he had no idea what the problem is. He thought that it was a "malfunctioning TV." However, I pointed out that there is no signal if the box is not rebooted. He tests the incoming line (and it's fine).

Thus, I can only conclude that the issue is with the box (and probably a software/firmware issue at that).

I've noticed on Xfinity forums (and elsewhere) that many people have similar problems. It seems like the issue is most often with Sony and Samsung 4k televisions. They describe the exact problem.

If the problem was really an HDMI cable from the box to my 4k television, then why is it that Comcast cannot detect the box (before it is rebooted)? Besides, my 4k Blu-ray player (as well as my 4k Xbox streaming) works perfectly with the same cables and in the same HDMI ports.

This is an issue with the box. I just don't think that Comcast even cares to look more intently into this.

Years ago, I had a high end Toshiba television that didn't work with HDMI. It worked perfectly fine with HD component cables. We tried the HDMI cables periodically until a Comcast in-home tech admitted that they had no idea why it didn't work.

So, we relied upon the component cables until we bought a new TV (because Comcast phone techs convinced us that our TV or its HDMI connections were defective) -- despite there being quite a few people on the Comcast forums with that same problem.

We kept the old Toshiba TV for a while and used it as a spare in the bedroom.  I plugged it in a couple of years later and PRESTO the HDMI cords worked perfectly. Apparently, a software/firmware update for the X1 box made it compatible with that Toshiba TV.

My issue here is that the box clearly doesn't work to the point that a signal cannot get through once per day -- and the remote line test fails. That seems to indicate something wrong with the box.

What is "remote line test"?

[chrismireya]

I guess that "remote line test" might not be the best way to describe it. 

By "remote line test," I refer to the signal test by the Comcast tech support phone representative who tests the signal to the box. Before I reboot the box (even with the light on), they cannot detect that the box is even plugged in. When I unplug it and plug it back in, they can suddenly detect it.  

Example: 

1. I use the Xfinity remote to turn on my Samsung 4k UHD TV. There is no signal from the box; so, the screen is black. I can still use the remote to control volume or switch to different HDMI inputs (e.g., Xbox One, 4k Blu-ray, etc.). I can still use the apps on the TV.
2. I call Comcast/Xfinity Tech Support. They run a test to my device. They cannot detect that it is on. They cannot even reboot it remotely.
3. I manually reboot the box (by unplugging the device, wait for a minute and plug it back in).
4. The Comcast/Xfinity Tech Support rep runs the test again. They now see the box. They can reboot it themselves.
5. The box will now work for about a day.

NEXT DAY: Repeat.

[4kUHD]

I have the same issue and have been trying to debug it.

It's not the cables, TV or AVR, it's the set-top box.

I can get sound from my AVR at times no picture on the tv and then try to change the channel to her if the sound changes, but the box is frozen. Login into my Xfinity account and do a reset and everything works within 10 minutes.

That sounds like a communcation issue of some kind (I have two 4k DVR's and neither of them has ever exhibiited this issue.)

[MSDOGS1976]

I signed up for cable back in March of this year and got the same 4k box discussed here. My box would freeze almost daily at various times during the day. Usually no more than once a day. Last week I finally got Comcast to send me a new box with cables and so far......no freezing. Not sure if it's due to the box or better cables. These cables are easier to snug up for a tight connection. BTW when I called Comcast to activate the box I asked this person if he had heard of much freezing and he said not much at all. He said in his experience it was usually due to a signal being dropped somewhere in the house(line problem). Who knows......

Hopefully my situation has been corrected but might be early to say for sure.

One thing to remember is that only those that run into problems end up on the forum. Most get things straightened out before asking questions here.

[chrismireya]

Yeah, I have tried everything. I've been on the phone numerous times. I've had a tech show up to the house. Nothing works until I unplug the device and plug it back in again. Then, it will work perfect all day....until the next morning.

I am tempted to try one more box (just in case). I'd hate to lose the 4k box simply because -- through bad luck -- I received several defective boxes.

[Whiteheather66]

Exactly same issue as described by you. This is my 2nd XG1v4. The first did exactly same until suddenly wouldn’t reboot. I also have Samsung TV with no problems with any other box including Apple TV, ROku or Amazon Fire Cube.

UPDATE: 

I don't know if Xfinity reps were reading this and acted upon it. However, I noticed an Xfinity tech outside of our home this past week. I don't know what they were doing. However, our Xfinity box has turned on every day since. This has been five days in a row -- something that has never happened before.

If that changes, I'll provide an update.

the x1 set top boxes do not 'turn off' they are always on. there is an option to go into power save (around a watt savings) that turns off the HDMI connector and the power LED. 

[chrismireya]

Well, I am speaking of turning on the TV with the Xfinity remote only to see nothing but "black."

Somehow, the TV turned on every day this week. It hasn't ever done this. It worked for about seven days. Each day that I pressed the power button, the TV turned on with picture. 

UNFORTUNATELY, it didn't work today. 

Ugh. 

I had to upplug the box, wait a minute and then plug it back in again. After booting, it will work fine. I wonder how long this will work.

when the TV turned on and you had black video image, was there normal audio? if not, next time press the xfinity button  or channel up/down button and wait 20-30 seconds to see if box wakes up.

[Gnocchi71]

Same thing going on with mine.

I am on my second box. When you turn the tv on in the morning. First box said no signal. Second box is just a black screen. And it doesn’t boot up. It is becoming a waste of time between the phone calls and running to the Xfinity store. Second box they sent me has the old style remote. Don’t know if box is an older one.

[jnelson2000]

Exact issue here. Happens on both of my XG1v4 DVRS. Doesnt matter if connected to my AVR or direct to TV. Only been a customer for a week. Seriously thinking about going back to DTV. Doesnt matter if display is set to 2160P or 1080P. Black screen and no sound until reboot of box.

hi, I only see this when they update the firmware version or the XRE menu software. the issue seems to be that on first reboot after the change the 'settings' for powersave that are stored is not loaded with the first boot. If you have power save 'on' then that is causing your TV to drop connection with the set top box (a TV issue).  I use the TV remote when 'black' (no signal on that HDMI port) to change selected HDMI port to a live one (like DVD player). then I change back to the DVR HDMI port and the box wakes up. My other DVRs (3) don't have that issue, only the xg1v4. 

[serviceman77]

Same issue here. Going on my 3rd tech visit in 3 weeks. Dvr has black screen but 3 satellite boxes work. U plug dvr and all of for 1 day or so. Other problem is dvr works but 3 satellite boxes have purple screen with Something not right. RDK 10000. Lines outside replaced. Fittings on pole. Amp removed. Every morning the box needs to be reset. Cannot send refresh signal from Xfinity account app. Tech coming out in the morning but I don’t think it’s going to do any good. Last visit dvr and 1 satellite were replaced. Added screen shots of the errors.

[chrismireya]

For the record: This issue persists. I have to unplug the XG1v4 box every day and wait for it to reboot in order to use it. After this, it will work....for the rest of the day. The next day, it will require another reboot.

I did notice that if I leave the TV on past the time that it is usually refreshed during the middle of the night, it will work the next morning.

[serviceman77]

It was a main line signal issue. My signal was too strong going into my home. I guess they replaced the main line on the pole this summer and did not adjust so when the cold weather came it activated the line amp in the neighborhood causing the signals to increase. An hour after the tech left there was a line maintenance worker out and they adjusted something and now I have almost perfect signals. +2 to the model compared to +17. Might want to have them out to look at your main line.

it is an often reported issue and even happens on my own xg1v4. I'm guessing that 2 things cause this: firmware update does it for me each time, and 5 hours will often put my xg1v4 into powersave mode even though it is set to off in device power settings. So far Comcast has yet to adress the issue. To fix it for me when it happens I use the TV remote and change to any live HDMI connected device (in my case Chromecast dongle). then change back to DVR HDMI port and the xg1v4 begins sending video (or the box handshakes with the TV). 

[Gnocchi71]

I went into power settings. Thinking I could have it power down in the night and i could just turn it on in the morning. There was a power off option, so I manually powered down. When I turned it back on signal was lost. So when the box powers down or resets in the middle of the night, it never sends out an hdmi Signal after restarting without unplugging.

Any other suggestion to try?

[jnelson2000]

I believe you may be right. I have a XG1V4 connected with an Audioquest Carbon 2M HDMI canoe to a Marantz AV8805. Every day I turn on the TV for the first time I get a no video/audio and have to reboot the DVR.

Out of curiosity and to prove what you said, I turned off my Marantz 8805 and rebooted the XG1v4. After 15 minutes I turned on my TV and AVR and to my surprise no video. I can now reproduce this bug.

This is definitely a HDCP handshake issue and should be corrected via a firmware update. When? Lol. No clue.

Try this....

Plug 4k DVR HDMI cable directly to your tv one night.  Eliminate the AVR sound system.  Many times it's the AVR sound system especially Denon receivers.

If 4K box stays on after nightly update then Leave the 4K plugged directly into the TV and use TV's ARC HDMI out to AVR receiver rather than 4k box to receiver THAN to TV.

It sounds like the 2.2 handshake is not passing through.  Either your AVR receiver needs a firmware update or you must hook 4K dvr to TV THAN to AVR receiver using HDMI ARC out.  Usually TVs have one of their 2.2 HDMI inputs capable of ARC 2.2 out.

Okay, I just replaced my old DVR with the new xg1v4 and found I have the same problem as many others, the DVR will not wake up when I turn my TV on in the morning. I have a new Vizio series E55-e2. This problem is a real pain and from what I gather from reading all the posts online this is definitely a Comcast issue, being firmware, software handshaking, whatever, it's their problem and needs to be fixed. I just need to know if they are truly working on it and some kind of estimate when I can expect a fix. Should I return the DVR, but then I'm not sure if they have an older model. Should I call Comcast support, but from what I gather I'll just get the runaround. I guess I'm just venting and looking for some guidance on what I should do?

I’m having the same problem. Replaced the set top box but it made no difference.

Come on, Comcast, address this problem!

So I figured I'd call Comcast support, of course I got someone in the Philippines that didn't know and gave me the run-around about the issue. I then found an old number for a Comcast rep in my area that I've used in the past and called him. He said Comcast is very aware of the issue and they are working on it and on the next firmware update it will be fixed. He apologized and asked me to be patient, but did not give a date when the new release will come out, hopefully soon.

the xg1v4 seems to go into powersave mode even though settings say off'. I use the TV input remote button to change to another active port (like Chromecast) then back to DVR and the connection is back on. never had the issue with the xg1v2 model.

As noted above, if I turn on my DVD player connected to HDMI-2 and play a little bit of the DVD and then switch back to HDMI-1 where my TVs connected the TV now works. It's still faster just to unplug the DVR and plug it back in.

I have grown accustomed to rebooting my box every morning. I've been doing this daily for SIX MONTHS. I visited my parents during Thanksgiving and forgot how nice it can be to simply turn on your TV and have instant access to programming. 

The sad part about this is that Comcast reps have promised me a "credit" for my inconvenience several times; yet, no credit ever appears on my bill. I'm used to the "Comcast letdown" now.
