OK DS, I've got more stuff for you to try out. The following two files are IR files with lots of upgrades in them, all of them supposedly being for Skyworth TVs. The first file has 19 upgrades, the second has 4. There are no macros to make it easier this time, so you will either need to come up with some macros yourself or just try the codes one at a time.

Good luck.

Thanks Rob.

I'll post the report here after I have tried all these upgrades.

Tried all 23 upgrades, Rob. No luck.

Don't feel bad about giving up right here... :-)))

I think you've exhausted the JP1 and UEI knowledge on this brand now.

Remind me, did you try the conventional remote search for this, i.e. using the 991 command?

Yes I did, after having had an embarrasing (on my side) conversation with Vicky on Page1 of this thread. :)
t'was to no avail.

Oh well... after all, knowing how to give up may also be useful in this life... :-)

Based on guess-work and finding this posting about Akai TVs declaring themselves as Skyworths, is it worth trying all the Akai upgrades including the Akai multiple upgrade in the File Section?

underquark, thanks. I guess, it doesn't cost me anything to try - I will report the results here once I've done that.

Try these trident/akai upgrades.

Try these two upgrades also, they need the protocol upgrade below. They are just the power keys.

Upgrade Code 0 = 02 05 (TV/0517) keymap-master Device Upgrade (KM v9.20)
3D 00 11 F8 FC BE
End

Upgrade Code 0 = 00 D9 (TV/0217) keymap-master Device Upgrade (KM v9.20)
3D 00 11 F0 FE 7C
End

Upgrade Protocol 0 = 00 3D (S3C8+) pid: 00 3D (KM v9.20)
00 00 21 8B 14 85 E5 A0 10 05 07 00 06 00 1B 00
06 00 52 D6 95 00 06 00 BF E4 04 08 E4 03 06 8D
01 46
End

Tip: When creating an upgrade, always include ALL functions from the oem remote, even if you never plan on assigning them to a button. Complete function lists makes an upgrade more helpful to others.

underquark, Vicky and Rob,

Finally some good news...

The upgrade Akai_TV05 from the pack suggested by underquark has a correct protocol (NEC1, 32). OBCs are completely wrong, but this is a minor detail.

So, I have not tried further upgrades from the pack (Akai_TV06 and onwards, or maybe I should? ) and concentrated on figuring out the correct OBCs instead.

Pretty much done them all now, except "OK" (there seems to be something inherently wrong between me and the "OK" OBCs in JP1 remote controls - they just don't like me! :-))) and "A12" (A12 is a selection button for audio part of Skyworth proprietary digital processing engine. I have found V12 - video part - selection OBC, but not A12, alas)

Hence the question: I have only tried the OBCs from 0 to 100 so far. (just plain ran out of time last night). What is the full range of OBC values for this protocol? Is it 0 to 127?

Any other suggestions are welcome, of course.

But even what I have now is already a win for sure. Let's see if we can improve it, but if not I'll upload the upgrade soon as it is.
----------------

Oh, BTW, Vicky, your two upgrades ("Power" only) above didn't work.

If I remember correctly, the NEC1 codes usually occupy 0 to 31, miss out 32 to 63, use 64 to 95 etc. although I don't believe that they have to do that. Here is a mapping of codes for my Topfield TF5800PVR (which also, co-incidently, uses NEC1, Dev 32). The digits on the left column are the "tens" of the hex value and the digits along the top the units, thus the OBC for OK is Hex 1F in my table or Dec 031 - for my device, of course.

Okay, I have tried all possible "OK" EFCs for all NEC1 protocols listed for even remotely possible devices from lookup tool (brands included Akai, JNC, Maqma, Technotrend, Time, Telefunken). That covered also Akai TV/2232 (BTW, Vicky, 245 is the EFC for OK from that set code, not OBC).
I have also tried all OBCs from 0 to 140 and 240 to 255 (just didn't have time to test ALL 256 OBCs).
I have not found OK button.
I am starting to think that the original remote doesn't have the OK button, as the selections can be made by other keys (left/right or numericals).
Anyway, I will try the rest of OBCs (141 to 239), and then post the upgrade here, whether I wil have "OK" found or not.

Or, btw, I haven't found A12 either.
