I replaced C408 (.0082) scan cap Sony says will blow F470. Resoldered 
most of the converg. board (sony says jumpers have bad solder conn). 
Cleaned both sides of screen and lenses. Smokers: Nicotine stained along 
with all the boards brown.
Question:
It seems I see a very slight horiz. jiggle in the picture on cable and 
on my sencore sig gen all modes even HD 1080i. Dont know if I'm being 
"anal" or if theres something there. Maybe the nicotine? Other? barely 
noticible.
