Tube burn spots, white dots, and green splotches

[Mondomark]

Advance apologies if this might be in the wrong thread as these issues affect consumer & prosumer tube video cameras from the 80s.

During the filming of an experimental doc, a burn spot occurred using a Canon VC-50 Pro. I've created a short video on YouTube (http://youtu.be/QtnYkZpvWJ8) that documents the spot on a saticon tube, plus related flaws on other cameras for which any help in remedying (or minimizing) the issues would be greatly appreciated.

The additional flaws include what appear to be dead pixels on another Canon, a black spot on a Quasar Newvicon camera, and green stains that warps the colour registration on both Quasar and Sylvania (JVC) Newvicon cameras.

Cheers,
