Possible Interpretations

What to do

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 99B or 103B

channels lose their

authorization every few days.

 The COM46 network tuner is unable

find the guide data from the 101

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

 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.

No video on multiple channels.

 If the channels are supposed to be

coming from the same slot, it could

mean a problem with that COM46

card

 If the channels are on different cards,

it could mean an RF signaling

problem

 If the channels are on different cards,

it could mean a guide acquisition

problem

 Verify that the PWR and Tuner LEDs

behave as expected

 Verify that there are no authorization

problems with the affected cards. If there

are, tune to channel 100 and re-attempt the

authorization process

Cannot execute file transfers.

 Firewall might be blocking transfers.

 TFTP server setup issues.

 IP address issues.

 Disable third-party firewalls.

 Refer to Section 7 and check for errors in

upgrade settings.
