Just do a re-check on your PSU spec, look at it's duty cycle and has it got batteries fitted? Some PSU figures are maximim output "without" the battery load and at 50% duty cycle. You may simply be over driving the PSU without realising it....

Scott,

Preferably on a bench, try using a higher current output single regulated PSU, perhaps 1.5 or 2 amp, and put a test meter on the +12v input to the camera.

Run the camera with the lens removed (and unplugged), check the input voltage, then force the camera to changeover to B/W and see what happens to the voltage reading (make a note of displacement, recovery time etc.). Allow the camera to revert to colour mode and take note of what happens with the filter mechanism (is it slow / laboured, cranky etc.)

From what you've said so far, I'd still tend to think that it's probably an issue connected with the mechanical filter changeover.

Look guy's thanks for all your input and your proberly right it is me im ****. But when i do get back on site i'll try another type of psu, I've never tried this combo before its been samsung col/mono and dantec in the past.
