CABLECARD

IN-HOME TROUBLESHOOTING

1. It is recommended that installers bring along a couple of CableCARDs for troubleshooting, This
will help eliminate the CableCARD as a possible problem during the installation.
2. Before installing the CableCARD, installers should check that the Digital Cable Ready (DCR), also
referred to as a HOST, is functional without a CableCARD.
a. Verify Host (TV) Operation: The installer can perform this by connecting the RF cable to the
correct cable input of the DCR (there may be connections for a terrestrial antenna) and
verifying good picture quality. The DCR will display all non~encrypted analog and digital
content. (The DCR must not receive RF signal via an STB or accessory RF modulator.) This
will eliminate basic TV circuitry as a possible problem.
b. Check that the CableCARD is inserted properly. When inserting cable card push carefully but
firmly until you feel the card click into place.
c. Verify RF from Cable System Tap: The installer can also connect a cable set top box to
confirm reception of encrypted digital services. This will help eliminate the RF signal as a
possible problem,
3. If the first CableCARD installed does not result in a User Interface screen (also referred to as
MMI screen) within 5 ~ 7 minutes, try unplugging the AC Power cord of the DCR and reconnecting
it (to reset the DCR) then try to await coming out of the User Interface screen again. If this is
still unsuccessful, try another CableCARD.
a. To eliminate the possibility of a damaged CableCARD or DCR device, the technician should look
closely at the CableCARD device to ensure that none of the pinholes are blocked or clogged.
b. Check Host Interface. Using a flashlight, the technician should check the CableCARD slot on the
DCR TV to ensure that there are no bent pins.
4. If the second CableCARD is successful, make sure the CSR or Dispatcher knows the new MAC ID
and CableCARD ID to complete the installation. The original card should be marked accordingly
and returned for repair.
5. Check the CableCARD menu options. If the second CableCARD fails to bring up the User Interface
screen, the technician should refer to the diagnostic menus on the DCR for further troubleshooting.
The technician can pull up the User Interface screen manually through the menu choices. The
customer should provide the User Manual, so the technician can easily navigate through the
DCR TV menu screens. The table on the next page describes how to navigate the CableCARD
menu. The list of selectable CableCARD options will vary, depending on your cable service
provider or CableCARD manufacturer. The table also shows how to access diagnostic screens for
the DCR TV. Many of these screens are not described in the User Manual.
6. If the second CableCARD is successful, make sure the CSR or Dispatcher knows the new MAC ID
and CableCARD ID to complete the installation. The original card should be marked accordingly
and returned for repair.
