Remove black values in a modis merge image

the following image shows my actuall result of a merged modis image. I used pyhdf.SD to open and manipulate and plot the data in a loop. It started on the right upper corner. The plot is ok... put on some areas overlaped. The easiest way is to remove the black borders.

Merged Image

I wanted to use this:

np.ma.masked_where(rgb_projected==0.,rgb_projected)

rgb_projected is the original rgb matix.

rgb_projected = np.zeros((1000, 1000,3))

rgb_projected[:,:,0] = z_01[:,:]
rgb_projected[:,:,1] = z_02[:,:]
rgb_projected[:,:,2] = z_03[:,:]

rgb_projected.shape


whereAreNaNs = np.isnan(rgb_projected);
rgb_projected[whereAreNaNs] = 0.;
rgb_plot=np.ma.masked_where(rgb_projected==0.,rgb_projected)

The interesting thing is, that everything is True although the first valueas are 0.

Any ideas?
