Can you help identify the correct protocol for this remote?

Tried the identified protocol (Emerson 10) without success, looks like default protocol not the correct one.

IR learned signals at:

2. Type of device: TV
3. Year: ? 2004 ?
4. JP1/UEI Remote model: OFA9910
5. Do you have a JP1 cable? Yes
6. Still have original remote? Yes

ylaviolette, Some Viewsonic TV's do use the Emerson Combo Protocol, so this is probably a correct decode.

I don't see upgrades in your IR file that use the 00 65 Emerson Protocol.

I think we need to see that to figure out why your upgrade isn't working.

The only difference that I see between those learns and the Emerson protocol is the frequency (Emerson is 36.7 and these are 37.7). Normally a difference that small shouldn't be a problem, but just in case that is the cause, here's a protocol upgrade that runs at 37.7

Upgrade protocol 0 = 00 65 (S3C8+) PB v4.01
43 8D 31 8B 12 D5 45 06 06 01 B3 01 9F 01 B3 05
05 CC 6A 06 CC 06 B8 E4 06 01 56 01 03 8D 01 46
End

So, create your upgrade in the normal way (using RM or KM) and copy it to IR.exe, then copy the protocol above over to IR also.

Thanks to you both; It finally worked using the "Emerson Combo (4 devices)" the two other Emerson protocols (3 devices and single device) didn't work; I didn't have to use the protocol upgrade you provided Robman, however I noticed that the "Emerson Combo (4 devices)" already has a protocol upgrade of it's own which the 3 devices and single device doesn't have; for my knowledge, what is the technical difference between these 3 protocols and could I have figured out myself which one is the correct one except by trial and error? Was there something in my learned codes that was pointing towards the 4-devices combo?

Thx again, will post my new upgrades once I'm finished with my 15 devices... almost done.

I forgot to subscribe on this one, so here's a late post:

I used RM and device code 10.

Let me know if you want me to run further tests but on my end everything is fine for this one.
