JP1 Remotes

Joyful moment. I only blame myself for not trying that code sooner. As EXIT is not a discrete key, remote could be used from there.

Yes, I finally got what I wanted. No, OBC 255 was just the last candidate from 256 possibilities. What I mean is that I've tried it all and there's no service menu key as specified on the Service Manual (unless for my unit even if I had the original remote from the previous owner). But I managed to ...

So I build up a Irplus profile to try it once and for all. I was in disbelief at the F 255, so I decided to try the non GAPs, one by one until the discrete key called "Brightness". So it pop up:

As soon as I tapped Exit, the settings for the grown-up appears :D ...

By tapping any button.

So far I tested 92-101 (did nothing). 103, 106 and then... 108 and my heart almost stopped, all green display.

For documentation purpose: JVC D3 F108 Green signal.

When I'm braver after that maybe I'll go ahead.

Yes, all my test is based on VOL pressed first, and seeing if it works. I only test the service menu key after testing the basic buttons before. Nothing is playing, just blank AV input.

I also tested my setup from files from here with others TVs of mine like LCD and for example my 10" Toshiba CRT ...

Basically, the lead-in pair doesn't repeat, but the rest of the signal does.

Indeed! Is what I found here:

Which is exactly what repeats do in IRS. So I tried it again just to make sure and even with 15s, also holding with TV turned on, also tried ...

Thank you for the tips, very useful. Yeah, I saw your warning before, that's the main reason I will not try it now, as you can read above, probably I already found the OBC I need, I just need the long press thing sorted out.

If the instructions say to hold the buttons for 15 seconds, then that might be the part that you're missing, if your IR-LED method isn't doing that.

Thank you for the tips so far.

Yeah, I'm struggling with that right now. It's possible to simulate it by simple wave editing if I knew how in JVC ...

Yes, D3 should be my best chance. Before trying the gaps, there's an untested method for the menu service I should try before, still with the F 106. The author of this upgrade states that it was learned from "video status and display" in the link below:

Indeed! It's like an extra button. I think they did this way (two keys) to force only their product could open it, no reasonable reason for this.

By "gap" codes you mean that I should for example, in IRScrutinized, under scrutinized remote tab add empty signals and manually try all the OBCs(F ...

Could someone please, learn the VIDEO STATUS and DISPLAY pressed simultaneously and share the update file with this code included? I think it's not possible from an UEI remote, just the original JVC or JVC OEM ones, but I'm not expert. My replica can't do it, JVC used ones are impossible to find ...
