help! stranded with purple problems - HD deck

So I used this deck earlier in the day no problem, then it got used for tape outputs from FCP, and now when I try to digitize again the image is purple...

It is a Sony HDW M2000 (HDCam deck).

I have no separate monitor sadly, just my computer screen.

Using FCP 6.0.2, with a KONA card. I have tried various capture AV settings, from the AJA 3 ones to the DVCPro HD ones, to no avail. The tape was recorded at 1080/23.98PsF.

Any wisdom or anecdotes warmly accepted,

Marla

Might try ditching FCP prefs and also reinstall Kona drivers.
