More than half of my channels are not working

[Molecular]

I finally got my HD box hooked up and working but more than half of the regular and HD channels are not displaying. The banner on the bottom shows up saying what's on but, no picture or sound is displated. Any suggestions?

Connect a box from another room and then connect it back up to normal.  I had to do that the other day and it worked.

that can work, 

also verizon has the in home agent built into the box that works real good

go to

menu

help

in home agent

run that and see if it gives you any errors

if you get a low DB or SNR

then that is talking about the coax cable going to the wall, so you will want to unplug it at both ends and plug it back in nice and secure at both ends

if that doesn't fix it, then seriously consider replacing that one cable.    they are inexpensive.    3 bux bought me 12 feet a few months back.

Its more than likely a cabling issue to the box.  To check whats called
your, SNR number, you'll need to do a little troubleshooting.  The SNR
number, is the signal strength to the box.
First turn the STB (set top box) on.
Second, on the front of the box, there are a bunch of buttons, you'll
need to push the Power button once, and the select button twice.  Not
holding any of the buttons, but kind of fast when you push them.
This will get the box into the diagnostics mode.  If it says general
status, you went to far, just push the left arrow to get you to the
selection screen.
Now that you are into Diagnostics, just use the arrows on the front of
the box, or the remote, and cruise on down to D04 if you are on an HD
box, or 03 if you are on a Standard Def box.  Now push Select.
On this screen, near the bottom, you'll see your SNR Number, it should
be somewhere above 35, for all channels to work.  If it is below 35,
try reseating the coax cable on the back of the box, and if that
doesn't get it up, try reseating the coax cable on the wall.  If it
still doesn't improve, try the box in another room, if its still below
35, its the box.
If its above 35 in the other room, its the cabling in the first room.
Try replacing the coax in that case, if still not above 35, call
verizon tech support, they will need to send out a tech to check the
inside wiring and the splitter at the ONT
