Help with collimating binoculars

I bought a pair of 10x25 tasco binoculars from e-bay (no warranty - yeah, I know - slap self on side of head - hard) for my daughters for christmas. I didn't expect much from them but I was pleasantly surprised at how much I could see with them.

Then I was reading one of the messages in the forums and it made me go and check both pairs. And unfortunately, one of the pairs is out of alignment.

The right side is perfect, the left side however shows a ghost image to the top right. I pulled the binoculars apart (as you do) and put the prism from the right side into the left and it was perfect. So ... I have narrowed it down to the prism from the left side but I have no idea how to re-align a prism.

Has anyone had this problem before and do they know if it was fixable.
Or have I done my dough and should I just buy another pair.

Please help.
Denis.
