ADV7511W - I2C ISSUES ( Read Fail )

I can talk to ADV7611 via I2C (bus seems okay), but I’m having an issue talking to ADV7511W via I2C.  

 

I am trying to read register 0 at address 0x3D
(7-bit) but getting a read fail.  Using a I2C analyzer, it don’t seem the
device responses at all.  Power rails are okay.

Note:  I have a pull-up at the PD pin.

 

Thoughts or any tips on what I should do?
