I'm having the same problems with my ECL Westerns, more often being blank,
or with very poor signals, than working. The developer is working OK and
the only reason we could come up with was that something must be
interfering with the reagants in some way. The reagants are made up in
sterile containers though so we are a bit stumped as to what the problem
could be. 

I may have missed the start of this thread so I would appreciate any
thoughts anyone has on the problem.

Thanks in advance
