Hi!

 

I have a question about ADV7181D.

I'm asking to give me more information but we have to solve this problem as soon as possible so let me ask one question now.

 

Our customer are connecting three CVBS to ADV7181D.

Some time when they change the ANALOG input , pink image outputs appear or there is no output.

After there system detect NG(No good), they use software reset.

And after the software reset, they read back all registers.

And there were some difference between after NG and after OK.

 

 

Can you give any advice what is happening to there system?

Some of the register which is different between NG and OK are hidden register so we can not understand what is happening.

 

Also I am asking to my customer to give me more information so I will update here if I got more information.

 

Best regards

Kawa
