I must therefore use the "search" mode to program the remote control: you have to press a sequence of keys, then press several times (up to 150 times according to the manual) to find the right setting. In my case this was done at the end of forty support.
Then the usual keys work perfectly: switch, choice of channel, volume. For rarer functions (settings: brightness, format ...) it seems to work for but try a little all keys to get there.
Update 09/2013: Some features of my tv are not played on the remote control: showing / hiding subtitles, choice of input mode (tnt / VGA / HDMI / USB ...): I remove one star compared to the initial rating
One regret: the key to mute the sound is not with a picture of speaker cut but with the English "mute".
Furthermore, the remote by its shape and manufacture of buttons is quite pleasant to use.
For less than 10 euros is a bargain.
