Satellite TV Diagnostics
I get a black screen when switching channels
Double-check your adapter settings and ensure any unused adapters are disabled then re-save.
I receive a Media Not Available message
If you receive a Media Not Available message while in Satellite TV it means that something
has caused VDR (the application receiving the signal) to terminate.
Manually type in a FTA channel and check the strength and the quality of the signal by
pressing the Menu button and select Signal Information. It is important that both meters STR &
SNR are steadily in the green.
●
If the values are too low you may need to readjust or increase the size of your antenna.
●
If the strength(STR) is good, but the quality(SNR) is poor or fluctuating:
●
It may be that you are getting interference(noise) somewhere between your
antenna and your CW-3000HD. That being the case you will have to recheck
your cabling and any other component in between (diplexers, splitters, barrel
connectors, etc.). Start by simplifying your setup and use a direct line. If that
solves the issue add any component back one at a time until you can determine
the culprit causing the noise.
●
It may be that you have an improperly grounded antenna setup. This can cause
fluctuations and tuning problems. It is strongly advised that you to read National
Electric Code if you plan to do the dish installation yourself. Particularly, section
810-20 or hire a certified technician/electrician to do the job.
●
It may be that you have inadequate cooling. Poor airflow can cause the tuner
cards to decrease efficiency due to heat. If the issue started shorty after the
addition of a hard drive it may be that some cables were accidentally moved and
are now impeding air flow.
●
There might be a slim chance that during shipment the internal tuner cards
became slightly unseated. Disconnect the box from power and open the top lid.
Locate the tuner cards. Unscrew, remove, then return it to its original slot to
ensure it is properly seated. Repeat for the next card.
Try creating a new user profile to see if it is limited to a specific profile.
I get audio stutter on some channels
This can sometimes happen if a channel has a low quality (SNR) signal. To verify that this is
most likely the cause check the strength and the quality of the signal by pressing the Menu
button and select Signal Information.
●
A commonly used method to minimize the stutter is to briefly press pause then press
pause again to increase the amount of prebuffering.
