From article <1991May18.161722.21388@colnet.uucp>, by res@colnet.uucp (Rob Stampfli):
: The most common problem with 3B1 monitors is a failure mode where the right
: side of the screen becomes increasingly nonlinear.  Once this starts, it
: proceeds at an exponential rate until the monitor fails.  The problem is
: a bad capacitor in the flyback circuitry.  If it is caught prior to the
: actual failure of the monitor, this is all that has to be replaced.  Once
: the capacitor fails, it takes out many hard-to-replace parts, like the
: flyback transformer, effectively rendering the monitor unrepairable at any
: reasonable cost.

Rob,

Can you tell us where this capacitor located and what size it is (or some
other way to identify it)?

Thanks.
