Signal and Picture Quality
Why is my picture not coming in clear? Why am I getting artifacts on the screen?
Digital signals will show a clear picture unless there's some type of interference. If you see some
artifacts on the screen but the picture is still there, you may need to use a different HDMI cable.
Why am I getting a "No / Bad Signal" message on my TV when my antenna is connected to
the DVR+?
Please ask your installer or qualified installation engineer to check that the antenna is in good
condition with no visible signs of damage. Check that the cable(s) between the antenna and
the DVR+ receiver are properly connected. If you have an older antenna, consult a professional
installation engineer to diagnose any issues with antenna system setup.
I hooked up my DVR+, so why am I seeing a blue TV screen with a "No Signal" message?
Please check that the correct input is selected on your TV and that the HDMI cable is properly
connected on both ends. If your TV's input is set to something other than HDMI, it will not display a
picture on your TV.
Channels and Program Guide
Why is the DVR+ not showing 14 days of guide data on some channels?
When connected to the Internet, the DVR+ will list up to 14 days of guide data for channels
associated with the ZIP code that you entered in the Setup Wizard. Channels that are not associated
with this ZIP code according to Rovi (the data provider) will display only the guide data sent over the
air by the broadcaster.
Why does my DVR+ not seem to find all channels?
Verify that the channel is still available using an up-to-date reference (antennaweb.org), and if
needed, perform a manual channel search. If necessary, download the latest software for your
DVR+, perform a factory reset, and run the Setup Wizard. After completion of the channel scan, all
available channels should now be listed.
Why does my TV get more channels than my DVR+?
This is uncommon, but unfortunately it can happen from time to time. All tuners are different and
respond differently to signal strength and quality. If your TV tuner picks up a channel that the
DVR+ does not, this does not indicate that your DVR+ receiver is defective. The DVR+ tuning
sensitivity is controlled by software, so only software improvements can be made; another DVR+ unit
will likely provide he same inconsistency because the hardware is identical.
If your DVR+ is not receiving a specific channel or the signal quality is not the same as you
experienced on your TV, we strongly suggest trying to improve your signal strength and quality by
changing your antenna's location, replacing your antenna with a model with more gain, or adding a
pre-amplifier.
In many instances the DVR+ tuner will outperform TV tuners in certain areas, and in other instances
the TV tuner will outperform the DVR+ tuners in another area. If you continue to have problems with
channel/signal reception with the DVR+ in your home, we strongly recommend hiring a professional
installer with the correct tools and signal analyzers to troubleshoot what's causing the issue.
