After following the topic:

I have doubts about what kind of Ambilight the 42PDL7806/12 should have?
Mine only have one colour each side.
Which means "ambilight spectra 2" that is mentioned in spec?

Update, my mistake after all if I look in the back of Tv I have multicolour ambilight, but in the wall I only see some kind of one colour effect.
