@ Thefish -Hi - it's a Harmony 555 and a LG 42LH4000 model TV.
@ makitamark - I've already looked at the IR Codelists and although I may have missed it there didn't seem to be much LG stuff ?
Regarding current LG Hex Codes - I don't have any at the moment but I'm about to dig up my old Plam M100 PDA (LOL) and load a trial URC Program which should I think allow me to learn a couple of codes and dump them out.
When I get them I will post them back and also the "corresponding" RS232 Codes if that's of any use ?
