JP1 Remotes

1. Device: IS-TV040922
2. Type of device: TV
3. Year: 2005
4. JP1/UEI Remote model: Comcast 1067BX3 jp1.3
5. Do you have a JP1 cable? No
6. Still have original remote? Yes
7. Checked the file section? Yes. I found a code for a similar model with same original remote, but my Comcast remote won't accept that code at all. It gives me the one long "rejected" blink when I enter the code (TV/0019). I do not have a JP1 cable so I can't do upgrades automatically.
8. Checked Pronto file section (at R/C)? Yes. All codes were for Philips remotes, and my computer can't read .CCF extensions.
9. Partially working setup code? TV/1523. Buttons are all scrambled but still work. I have figured out several of the EFCs by trying all those listed in the Lookup Tool. So far, I have 44997 Power, 13253 Channel +, 12997 Channel -, 12229 Volume+, 11973 Vol-, 44485 Mute, 44229 TV/AV, 27845 Menu, and all numbers in order from 1 to 9 and 0: 61893, 61381, 62405, 60613, 61637, 61126, 62149, 28101, 29125, and 60869. The Closed Caption button is one of the few EFCs I can't find, but it is vital that I have that key.
10. Learning remote question? N/A
11. Have you tried the JP1 Lookup Tool? Yes, I found code 1523 and tried all listed EFCs, resulting in the codes in number 9 above.

Give 23781 and 44517 a try

Neither code appears to do anything at all.

Your EFCs so far yield OBCs (function numbers) that are 0-9 for digits 0-9, and ranging up to 31 for Vol-. You can search on all 256 possible OBCs using the following formula for EFCs.

EFC=n*2048+1221 + c*256, where n ranges from 0 to 31, and c runs from 0 to 7. I think you should search on the lowest OBCs first, and the order of n to do that is:
29,13,21,5,1,17,25,9,27,11,19,3,31,15,23,7,30,14,22,6,2,18,26,10,28,12,20,4,0,16,24,8. For each value of n, use all 8 values of c. If you want to get a strict order of OBC, use c in the order 1,5,3,7,0,4,2,6.

Or you can use RemoteMaster, and enter in OBCs from 0 to 255, and then (critical step) change each hex code from eg. DC 20 to DC 00-- the second byte must be 00.

I used Excel to make a column of numbers from 0 to 255, pasted that into the OBC column in RM, copied the hex column to Excel, replaced all instances of <space 20> to <space 00> and copied that back into RM. That gave me the correct list of EFCs.

Vicky:
Bit 5 of the hex data must be set to 0. That's a control bit that tells the executor to compute the second byte of device by itself. 1523 has fixed data 8, 255,2,255, but we want to send 8.247, and not 8.255. For upgrades loaded by interface cable, this doesn't matter, since RM/KM will put 247 into the fixed data, but it does for manual entry of EFCs. So your suggested EFCs above should have been 23749 and 44485 (which was already established to be Mute).

5. Do you have a JP1 cable? No

In case you ever do get a JP1 cable, Found a match and recorded the IR signals with the JP1 tools to create the respective files.
