X1 Technical Issues

Yes - dozens of times as indicated in my posts.  And OK - internet doesnt matter - thats fine.  I'm not refusing anything, just indicating that signal strength seems ok.  So maybe quality isn't although phone rep said signal quality was fine btw - so I guess tech support is able to see that remotely?

Either way freezing on a just a handful of channels out of hundreds seems odd to me but I guess I will be taking a day off for a tech visit.

Can you please point me to another post where someone had just HBO, Cinemax, and Showtime freezing (with the HBO2 etc. versions of those working fine?)  Perhaps I missed them in my searches.

Thanks.

Update: here are my current power/snr readings connected to the splitter (cable modem on other leg of 2 way splitter):

Downstream power 6.8

Downstream SNR 37.8

Upstream power: 45

Within spec?

from previous comcast posts...

Upstream Transmit Power Level: 25 to 53 dBmV.
Downstream Receive Power Level: -8 to 10 dBmV.
Upstream Receive Power Level: -2 to 2 dBmV (technically should be as close to zero as possible)
Downstream Signal to Noise Ratio (SNR): minimum of 35 dB.
Upstream Signal to Noise Ratio (SNR) Individual Modem: minimum of 31 dB.
Upstream Signal to Noise Ratio (SNR) Channel Average: minimum of 31 dB.

My long standing issue w/ the X1 box is whenever I try to delete a show, it crashes.  Even after I watch a recorded show, when it goes to the 'DELETE NOW ' 'DO NOT DELETE' screen, even if I try to exit out, it hangs and crashes.  The only way I can delete is go thru the website.  I will try recording this and post the video here.    If my X1 box is faulty, will comcast switch out a new one for me?  at no cost????

hmm I found the problem it says made in China on the bottom.     Oh well it lasted 8 days. I will call tomorrow and schedule the tech to come swap it then

i have the X1 system with 1 DVR and 2 RNG 150N HD boxes. Today one of the boxes had a flashing yellow envelope data and did not turn on.  i called support they did something and its been flashing these threee lights now like kit from knight rider. The support guy said it would take an hour and it should reboot its been 3 hours. I am guessing this box is jacked????

Hi. Just had X1 yesterday. The second box in bedroom keeps changing between channels and won't stop. Saying temporarily having troubles tuning in, now tuning to previous channel. Is ANNOYING please help.

Pull the power cord on the unit and let it sit... for some reason it is seeing a continuous channel change from the IR ....if powering down and restarting do not fix the issue, look to get that box replaced!!!!

I'm pretty sure the Tech will get you fixed up!

I'll take  day off in a couple weeks and have a tech out.

Just for fun I hooked up a PPC evo 5 u/u and saw no difference - excellent SNR all around and still pretty high power readings downstream.

I then inserted a -9dB attenuator and everything showed closer to the ideal 0 downstream power and still close to 40 SNR - everything worked the same.  Upstream power was borderline at 50 - but again everything worked identically wether my signal was hot or attenuated (and I tried 3 and 6 db attenuation as well without any difference).

So it doesnt look like signal strength makes a big difference for me and my SNR is always close to 40.

So it must be something further upstream like you said.

thanks for the input.

Ok thanks.

I thought the in-band network readings (Summary, In-band Network) vs. (System, DOCSIS) were for whatever channel each tuner was tuned to.
