Re: VECTOR: Star Wars "bloom" problem with a twist:Update

Had the same after installing my wintron.

It turned out to be the wiring to the focus/screen block. One wire was
sitting loose in it's shrinktube.
Any change in beam current (especially such as with the ds explosion!) will
create a large voltage drop over this bad connection.
