We are using the ADV 7179 in NTSC square pixel mode, with a 24.5454 MHz clock. The output is displayed only in black and white, even when using the internal color bar test pattern.


We are in mode 0 slave option, using DAC A CVBS output, and our register programming is as follows:


MR0: 0x00

MR1: 0x38

MR2: 0x01

MR3: 0x00

MR4: 0x10

TR0: 0x08

TR1: 0x00

FSC3: 0x55

FSC2: 0x55

FSC1: 0x55

FSC0: 0x25


Do you see a problem with the configuration? Is there something else that could be causing this problem? Any help will be greatly appreciated.


Thank you,
