ADV7611 won't terminate the HDMI input

We are having problems getting an ADV7611 HDMI receiver to operate. It isn't pulling up (terminating) the TMDS input signals.

 

The transmitter is sending data and if we pull up a line to 3.3V with a 50 ohm resistor, we see the correct data.

 

All the power supplies are correct and we are using register settings from the ADV reference design.

 

We can correctly read back the register values and the device does output a clock and some sort of data.
