Then post in a thread designed to capture those brands that didn't make the Wii U's extensive list - like I did - and you never know where help will come from - like one of the members of the team that contributed to the Wii U's TV remote app.
Just keep the thread free of 'mine works' and 'you should have bought a....' comments and it'll be useful.
Anybody in Australia, New Zealand, or the UK with a:
Kogan 32" LED TV, model KHLED32XXXYB
select from the TV remote menu:
Brand: CMX
Remote code# : 2
For all other Kogan models, try the range of CMX codes first then post here if you still have no luck and we'll see what happens.
Any other unlisted HD TV brands are welcome to post for assistance but please also state which country you reside in.

Any ideas?
