Problem/ Condition
Possible Interpretations
What to do
IP Address = 192.168.0.0
Card has not fully booted yet.
An invalid IP destination was
entered.
Card rebooted with Persistent set to
„0‟.
Wait for the PWR LED to stop flashing.
Verify the configuration settings.
Try reprogramming the card, making sure
to set Persistent set to „1‟.
All tuners locked to 99B
channels lock and unlock
simultaneously, but only for a
few seconds at a time.
RF Interference from certain 2-way
radios can overpower the B band
converters, causing tuners to lose
lock briefly.
Due to its transient nature, no solution has
been identified.
Card required multiple
authorization “hits”
Possibly nothing – it could just be a
function of the way the authorization
queue works
Possible RF problems
Possible guide acquisition problems
Wait the full 24 hours recommended for
authorization.
Run through the guide acquisition spot-
checks. If all tests pass, tune to channel
100 and attempt reauthorization.
Verify that the account has been set up
properly.
Tuners locked to 103B
channels lose their
authorization every few days.
The COM24 network tuner is unable
find the guide data from the 119
satellite.
Revisit the RF installation guidelines.
Run through the guide acquisition spot-
checks.
Frequent macroblocking of the
picture.
If the weather conditions are
favorable, there could be an RF
signaling problem.
If only high-action channels are
affected, it could be a problem with
the QAM setup.
Try to isolate the problem to a particular
tuner or frequency by temporarily changing
the DIRECTV channel.
Verify that the installer has not attempted to
“stack” three (3) HD DIRECTV programs
onto a single QAM channel.
Pink and green blocks on TV.
Problem with the Pro:Idiom decode
path.
This may be seen at power-up of
some TV models.
The TV you are trying to use does
not support Pro:Idiom encryption.
Change the television channel.
Check television model for Pro:Idiom
encryption capability.
COM24 cards only tune to SD
versions of channels.
Possible RF signaling problem.
Possible guide acquisition problem.
Possible entitlement problem.
Revisit the RF installation guidelines.
Run through the guide acquisition spot-
checks.
No video on one channel.
Possible RF signaling problem.
Possible authorization problem.
Try tuning to other networks to rule out B
band converter issues.
Check the CAM log for authorization
problems. If found, tune to channel 100
and attempt reauthorization.
