About to try this out soon. Like others, I'll try out the Yrr first and perhaps Vs/Va after warranty lapses.
@zoyd, should I turn the TV OFF when adjusting the pot, then ON to test, etc... or is it safe to leave it ON when adjusting/testing? Also, are there notches on the Yrr pot so as to know where the default/factory was?
Also, by around how much did you turn your Yrr pot? Mine has exceeded 1/4 and I still don't see any sparkles/misfires in the scrolling pattern, nor any green/red dithers on a black image. Should I still turn it even if it reaches half-way? Just worried there might be adverse effects by turning it too much.
BTW, thanks for the great work (and the FBr fix too!)
