ADV7619 4k hdmi reset on signal loss

While receiving a 3840x2160 30 Hz signal, if the hdmi cable is removed and replaced, the Vsync from the ADV7619 is corrupt, has some -ve going Hsync pulses. I tried restarting the equalizer (http://ez.analog.com/message/113257#113257), but nothing short of re-powering the board seems to fix the situation. Any ideas or tips very welcome.
