46f510 when first turned on the picture will flash very quickly between dim, bright. center will jump out of focus quickly then flash back. in service crossthatch, lines will be blurry then quickly jump up and down changing from blurry to sharp very quickly. slight static crackle from flyback, when displaying different dve test patterns, flyback lightly squeels at different pitches and volumes depending on what pattern is showing. you can feel static charge while getting near flyback. thanks icaillo

46f510 while doing service convergence crossthatch, at first the center will be sharp and in focus, and the outsides will be blurry. as time goes on it the center will gradually become blurry as the edges get sharp. does this sound like dynamic focus transformer? when veiwing tv it will do the same thing. thanks for your help

Re: dynamic focus?

any cap around there or through experience are you led to common culprits. YOu must remove to test I believe. is radio shack quality sufficient. if so i will go ahead and swap them all out since i have to take them out anyways. thanks
