I sure do !

I cap'd a 19" G05 to try to solve an intermittent problem, this didn't help so
I decided to shotgun the transistors in a pre stage (both X & Y) and it got
worse. Only after close examination, I found out that I replaced them all
backwards ! I attributed this to either bad silk screen or the "D's" were
reversed on the generic replacement transistor(s) TIS98's. It works now,
but it drove me crazy at first.
