Thank you very much!

I'll try to decode with the tools you linked.

I tried to send the signal a longer time (i didn't use macro and i don't need them).

All i need is to get working hex codes for the functions 251 till 255. They didnt work, so i thought i made something wrong with makehex, so i thought i should try my own generated hex codes at first with the power on function which also didnt work as i have written.

I use TotalRemote on my PDA.

I'm only doing this because i need to access a menu which is only accessible with a special service remote from LG. I got the codes and (251 till 255) now i only need the matching hex codes for the functions 251 till 255.

Maybe, can you generate these hex codes for me or tell me what am I doing wrong with makehex?

This is how i generated my Codes:

makehex nec1.irp myhexcodes.txt

content of nec1.irp:

Device=4
Function=0..255

Protocol=NEC
Frequency=38000
Time Base=564
One=1,-3
Zero=1,-1
Prefix=16,-8
Suffix=1,-78
R-Prefix=16,-4
R-Suffix=1,-174
Default S=~D
Form=*,D:8,S:8,F:8,~F:8,_;*,_

Then i tried the matching functions that should work (like power, mute, etc.) and they didnt...

Thanks a lot johnsfine, it's so good not to be left alone with a problem and materia i don't understand :)
