I tried to convert my Nikon D70 into IR and after replacing the filter and reassembling the camera, I am unable to take any new pictures. I am able to see pictures that were previously present on the CF card, but new images are not previewed or stored to the card.

The shutter, focus, LCD and metering work fine.

What could have gone wrong? How do I verify if my sensor board is zapped or the problem lies elsewhere.

Thank you.
