IPG Troubleshooting

Welcome to IPG Troubleshooting for the 4DTV

The 4DTV Integrated Program Guide is an integral part of the receiver's charm and ease of use. It was also a key selling point of the box.
The IPG should be trouble-free, but unlike other IPG products, this one must take the data and run.
It requires 5 things to run:
a) A Subscription
b) Authorization
c) A Good data stream
d) Good Channel Coordinates
e) An opportunity to get 861 packets of data 

 

In order to check out IPG problems, you need to "Demand" a guide download.

The easy way to do this:

IT is as this point that the diagnosing of an IPG problem can begin:

A properly functioning IPG will have distinct characterisitics.

by checking these areas, one might isolate the problem.

First, you must be subscribed to the IPG.

 Beginning 1/1/2001, the IPG is now a PAY ITEM. The 4DTV will not tune to the guide at all if you do not have a subscription to it. Instead, it will simply bring up the guide bar at the top of the screen and will not tune to the guide channel. If this happened to you, check with your programmer to see if you are explicitly authorized for the guide. Get a Subscription or a Re-hit  if this is happening to you.

Second, it will tune to the right spot to retrieve the IPG.

The US IPG's channel coordinates are:



Check it by using OPTIONS 6-5 Line J for polarity 

 

 

 

 

 

 

 

 

 

 

 

 

 

and Diagnostics C for the other things. 

a) press options
b) press 6
c) press 0
d) press 5
e) use the right arrow to arrow over to Diagnostics C
f) Look at line 1, on the left
g) note the number is 07. This means a DCII Lock when tuned to a DCII channel. Confirm by looking at the front of the receiver for the
Green DCII Light.
h)
Look at line 3, on the right.
I) the  +9.5 is the signal level. Confirm with options 6-5
j) Look at line 4, in the middle
k) note the number 1:50 1270.000
l) the 1 is the Channel Catalog number. All Channels listed in the IPG have unique number. The actual number 1 means channel is the IPG.
m) the  50 is the Service Number. The service number is used to differentiate between channels in a DCII multiplex.
n) the 1270.000 is the I.F. frequency value.

It should look like the following Display while the IPG is downloading:


If it does not look like this:

Failure at this point indicates no guide authorization (see note above), bad channel maps or No Signal. See: Fixing the maps. 

If you are certain the maps are correct, check Options 5 for good signal/quality levels and the front panel for a Green DCII lock light. Adjust as necessary.

The third thing to look for: Stream Authorization

Assuming the 4DTV has indeed tuned to the correct channel, Refer to Diagnostics B. The bottom 2 lines indicate Authorization Status. You can get the guide if you have a status of any of the following:

If the status is US/US, NS/NS or MP/NS you do not have authorization.
Additionally US/US may mean a bad signal or bad channel maps.

Diagnostics B currently looks like this during IPG retrieval


The Fourth item: An opportunity.

The 4DTV is made to automatically tune to G0 during the night while the receiver is OFF

You may disable this setting with options 642. 

Additionally, it will not automatically tune to G0 if you do not turn off the receiver at night.
Failure at this point indicates:
a) Auto repoint is disabled
b) the receiver was on all night

c) No Guide subscription
If the guide did not load or does not have current listings and you have a subscription, 

you will see the following message in response to pressing the guide button:


You may also see this:


The Fith Item: A good data stream

So IF you gave the box:

and it stil doesn't update, the data stream itself might have a problem.
Diagnostics F will tell you if the stream is ok.

If the stream is OK, Diagnostics F will look like the display below. 

A good running data stream will cause the numbers in the rows after the d: to update.

Below the d: you see a 15. A number in this spot corresponds to the number of unreceived/rejected packets. The lower the number in this spot, the better. 

Below the 15 is a number 861. A number in this spot corresponds to the number of total  IPG packets.

The next 4 lines below the 56 and the 12 represent data. 

Diagnostics F during normal guide retrieval.

 

 

 

 

 

 

 

 

 

 

 

Indications of Failure at this stage:

Dysfunctional Diagnostics F

 

 

 

 

 

 

 

 

 

 

 

 

 

Diagnostics F: will have many 0's after the d:

Additionally the number 849 is a dead giveaway that something is very wrong.  

Solutions at this time:

 

"Your Satellite Provider" , NPS or HBO Direct among others, will $ell you a guide subscription, likely as part of a package.
