Mmmmm at this point in time, a machine has to be fairly special to warrant me bothering with a flyback replacement. If one were to fail on either of my iMacs for instance, I dare say at this stage I would simply just replace the whole A-board with a known good unit. If I had something rareish like  a Lisa or something then obviously that would change things a little.

But yes, an LCD swap sounds like a better long term option if you arent a stickler for authenticity.
