Sony Trinitron monitor

[Kiwick]

Hi you all.

My 2000 Sony HDM-200 trinitron monitor has slowly lost horizontal width over the years, now i'm just right at 96% and i have very little H.W adjustment left... the geometry is otherwise excellent.

I have already resoldered the entire chassis about 4 yrs ago as it had some assorted intermittent faults, it worked fine since then...

Is this one a simple fix or maybe i'm about to lose the flyback?
