Pixelation with fiber optic cables

All of a sudden six months ago my Xfinity 4K DVR started pixelating. I'm being treated as if it's all in my head.  The technician yesterday wanted me to find it on live TV while he was here.  Last night I used my phone to video examples for the next time I have a technician out.  I live in a new condo complex with fiber optic cabling.  I have had two new DVRs (one 1080 and one 4K), all new cables, technicians out that say my signal is fine, have had my signal reset, unplugged everything to refresh and I still have pixelation.  What else could be causing it?

Solved all my problems by installing this amplifier: PPC EVO1-9-u/u. Slight pixilation recently started again after hurricane Irma along with some slow responses from the remote. I unplugged the amp for 10 seconds today and all seems to be back to normal. Could be coincidence but this amplifier seemed to work great for some years now.

Thanks for the response and of course I’m wondering why Xfinity hasn’t suggested an amplifier or put one on.  I needed an amplifier at my last condo in the basement of the building, so I have a good idea what you’re referring to.  The old condo had cables outside underground, but at this new condo Xfinity keeps telling me all my fiber optic cabling is within my unit, so there’s no signal to trace outside to find out where or why it’s dropping off.  I’m guessing the amplifier would go somewhere in the cable panel in my unit.  The technician that was here the other day was very patronizing because I couldn’t duplicate the pixelation while he was here, so I keep taking videos of it on my phone.  Thanks for the idea and I’ll look into an amplifier.

Hello @user_d539f5

Thank you for taking a moment to bring these questions and concerns to our Xfinity Community Forum. I am sorry to read about the trouble with pixelation you've been experiencing and the trouble getting a resolution. Intermittent issues like this one can be tricky to diagnose if we cannot recreate the issue while we are working on it. My team is happy to help.

 

Is the 4K DVR your primary cable box? Or a secondary wireless box?

I no longer work for Comcast.
