ADV7181D CSC

We have an RGB (640x480) connected to the ADV7181D. The ADV7181D is connected to an IMX6 processor and i can see an image.

Problem is the colours are very green.

Trying to experiment with the CSC registers is put A1,A2,A3, B1,B2,B3 and C1,C2,C3 to 0 and give some offset with A4,B4 and C4.

I capture the ADV7181D output on a digital scope, but the offsets doesn't seem to work.

 

Also when i want to give offsets with tje Channel offsets register 0x77-0x7A outputs keep 0.

 

Using the Force default colour output (0xBF - 0xC2) register the output is as expected.

 

Is there any blok after the CSC which manupilates the data ?

 

Any other setting i need to configure ?

 

Regards,
