Blocking/artifacting on certain channels

[adams8281]

Most channels work great, but I get severe blocking/artifacting (and audio problems) on a few channels.

After doing many of the online steps (checking all cable connections, resetting the box, resetting the ONT, etc. etc.) it seems like all signs point to some kind of signal issue. Is there anything else I can try before paying for a tech to come out? Even for the TV that is just 1 splitter off of the main line into the house, I have issues.

Thanks

Shouldn't have to pay if issue is theirs.

Can you check signal level on closest STB to ONT?

Have you checked that cable connected to ONT is tight?

Last thing to try would be to see if you can reset ONT.
Depending on if you have battery back up or not, pull power.

Wait a minute or so and plug it back in.

Otherwise, call support and let them know what you have tried so far.

The box closest (1 split off ONT) has slightly less blocking/artifacting, but still displays this issue.

All cables were checked for damage, disconnected and reconnected. Through the self-help tools, I beleive the ONT was reset.

I tried contacting Verizon about this, and they indicated since it was likely a cable issue, that it would be my responsibilty (not theirs) and charges would apply?

If it is a problem with the coax cable, then yes it is your responsibility.

If it is the ONT, then it is theirs.

What model box do you have?

Also could you Identify Channels.  Some channels are know to have a lower quality signal (i.e source problems) while others happen to be at higher freuenceies were cable quality makes a difference.
