Alan,
You probably already
found this for the manual with codes for your Comcast supplied remote, but maybe you can try the "Searching for your code" process.
SEARCHING FOR YOUR CODE
If your home entertainment device does
not respond to the remote control after
trying all of the codes listed for your
brand, or if your brand is not listed at all,
try searching for your code.
For example, after trying all of the
codes for your TV, you still cannot get
the remote control to operate your TV,
then:
1. Turn on your TV.
2. On the remote control, press TV
once. Then press and hold Setup
until the TV key blinks twice, then
release Setup.
3. Enter 9 - 9 - 1. The TV key will
blink twice.
4. Aim the remote control at the the
TV and slowly alternate between
pressing Power and TV.
Stop when the TV turns off. A
working code has been found.
NOTE: In the search mode, the
remote control will send IR codes
from its library to the selected device,
starting with the most popular code
first.
5. Press Setup once to lock in the
code.The TV key will blink twice.
6. To search for the codes of another
device, repeat steps 1 to 5, but
substitute the AUX key for the auxiliary
device you are searching for.
CHECKING THE CODES
If you have set up the remote control
using the Searching For Your Code
procedure, you may need to find out
which four-digit code is operating your
equipment. Perform the following steps
after setting up your devices to find out
which four-digit code operates your
equipment. For example, to find out
which code is operating your TV:
1. Turn on your TV.
2. On the remote control, press TV
once. Then press and hold Setup
until the TV key blinks twice, thenrelease Setup.
3. Enter 9 - 9 - 0. The TV key will
blink twice.
4. To view the code for the first digit,
press 1 once. Wait 3 seconds and
count the number of times the TV
key blinks (e.g., 3 blinks = 3) and
write down the number in the
leftmost TV Code box (at end of
this section).
NOTE: If a code digit is “0”, the selected
mode key will not blink.
5. Repeat step 4 three more times for
the remaining digits. Use 2 for the
second digit, 3 for the third digit,
and 4 for the fourth digit. Finish
writing down the code in the TV
Code boxes (at end of this section).
6. To check another device code,
repeat steps 1 to 5, but substitute
the AUX key for the auxiliary
device you are checking. Write
down the codes in the appropriate
boxes below:
AUX Code:
Device Type:______________
TV Code:
