Nothing else seems shorting to ground. But we will see tomorrow after I swap the FTDI chip.
(I used ChipQuik to remove the FTDI chip instead of a heatgun. Quick and easy.)

Removal of the CCD... two steps (I can't remember in which order).

1. The sensor is glued (epoxied) to the metal carrier so you need to "melt" the epoxy. The usual procedure is to use an DMSO bath for a few days. It will completely melt the epoxy and the sensor will simply come off. It won't damage the sensor. Make sure you bathe the sensor long enough so that no epoxy is left on its back or it can affect the cooling performance later on.
Make sure you read the safety precautions for DMSO.
The usual supplier is ebay or chemists.

2. For desoldering of the sensor Brendan used the desoldering pump (watch for static electricity) on 4 sensors and I used ChipQuik on 3 sensors. They all survived. The recommendation is to keep the sensor as cool as possible so try to be as quick as possible.

Unlike D70, the D40 has a flexible PCB and that one can be removed quite easily, pin-by-pin.
