PCM1789: Output Signal Issues

Other Parts Discussed in Thread: PCM1789

I need some assistance or recommendations. The design is using the PCM1789 DAC that is mated to an NXP HDMI RX chip. We are seeing an anomaly whereby one color band signals is stronger and more predominant than the others.

What we are using is the PCM1789 in General Mode (no sync pulse). 

But we did note in the datasheet that the PCM1789 has a Video Mode that has a sync function that is connected to one of the color output signals. Although we are not using this function we question whether or not this could somehow be part of our problem.

I appreciate any assistance or recommendations.
