user: your support page is a piece of garbage. I'm trying to fix a channel unavailable error, and it keeps asking me to login. and then when I do, it keeps taking me to the main account dashboard, which is useless.
agent: We'll be glad to help! How many channels are you getting that error on?
user: Undetermined, a lot of them but not all. Not just HD channels. I've power cycled both the STB and VZ router (haven't touched ONT). For example 509 doesn’t work (CBS) but 550 does (USAHD).
agent: Appreciate that info! Can you try disconnecting both power and coax cables from the box and wall jack?  We want to make sure the needle wire is straight on both ends. Reconnect everything after 30 seconds.
user: It almost feels like an account provisioning issue, but I don’t recall making any changes to the channel lineup recently.
agent: That error message is associated to a signal issue.

Customer is stating the error in the chanel. Agent updated that it is due to associated signal issue.
