Attached is an LIRC config file for the Panasonic remote N2QAYB001010 (Panasonic Vierra TX50DX700B) as I wasnt able to find any other fully (or even mostly) working config files on the internet.
Every single button on the remote has been allocated (including the apps, netflix and home buttons) with kodi functions so you can reprogram any button you desire.
So for example there is no kodi equivalent for the AUX button so i’ve set it to ANGLE and if you want to change it to something more useful you can do it using the keymap editor addon (but Ive also included the relevant key code, where applicable)
This TV does support CEC so this may not be terribly useful for anyone else, but on my setup the IR reciever on the TV is kind of blocked so I can place the Vero one in a better place.
Unfortunately these arent hex codes, they are raw, if anyone knows how to convert them give me a shout.
