I came accross this forum while looking for help with my KDS Avitron 21" monitor. The particular thread is this one: http://www.daniweb.com/techtalkforums/thread5042.html
I have about the same symptoms, except after flickering for about a week, my monitor just stopped showing the picture, instead of having the picture in swirls. I attempted the "easy" fix that was suggested by TallCool1, but it didn't seem to do anything (that is, assuming I pulled the right wires).
I have pictures available of the insides of my monitor, but I can't get my web hosting to work ATM. I can e-mail them to anyone who may be able to help. Of course, I will answer any other questions you may have.
