Gun balance doesn't change in a week; if it was fine the first time, what
happened to require major gun adjustment the second time? I'd suggest trying
the
first procedure again, whatever that was, and seeing what happens. If its an
LCD, then using PreCAL on it may well be the issue. There are variables
ranging
from the video card, to the chipset, to the monitor make and model, to the
Spyder itself, but ColorVision tech support would be in a better position to
deal with sorting all that out, rather than trying to do it by guess on a
public
list.

That would all lean towards it not being the precalibration, or the video

Such things have been known to happen. email@hidden should be
able
to figure it out, or replace the unit, whichever proves to be needed.
