Edited to include build date (3/08) and SN#LB80630527 - do not know how to check my firmware. My Service Menu adjustments after calibration for the Custom Setting mode were as follows:
RD = DC
GD = FF
BD = 99
RC = 80
GC = 80
BC = 80
Red x = .679 y = .314
Green x = .268 y = .644
Blue x = .151 y = .060
I was told that, without a means for direct gamma adjustment, gamma level changes involve the relationship between Peak White APL and Black Level, and this is where your trained professionals earn their money. For me, the bottom line is my picture quality, which I am thrilled with after having my panel professionally calibrated.
Just out of curiosity, I don't really understand what all there is to calibrate on this set other than greyscale [huge I know] and the very basics: picture, color, tint, sharpness and black level. Your cuts are at the defaults of this panel [80, 80, 80] so it was your gains he changed. By the way, where did he set your Sub-Brightness, Color, Tint, etc. in your service menu, if you don't mind me asking? Also, post calibration, are all your user menu settings now at 50, as is typical after a calibration? If not, where are they? Thanks for any info.
AFAIK, there are not any major tweak settings for this panel. Geometry adjustments are not needed on plasmas, so that's a lot less work right there. Which is why I'm curious the price of a calibration was quoted so high to me for this set, almost double of a tube CRT set that I had done that had TONS of settings and adjustments and tweaks, not to mention geometry. If anything, since so little [by comparison] work can be done here, it should cost half as much, unless I'm missing something (?).
From my look into the service menu, there is hardly anything at all to adjust in this panel except for cuts and gains, sub-brightness, color, tint, and contrast. Most disappointing of all, no gamma adjustment.
I've seen the data on three sets post calibration now, and for some reason, cuts always seem to stay at the default of 80, so nothing done there, we can all do our own basics with our calibration disks and get those close enough (though I couldn't even find a way to turn off colors entirely in the Service Menu [which came in handy on my CRT's when adjusting color and tint]. Which leaves... gains? Three settings adjusted for near half a grand? Ugh.
I've spent so many hours tweaking my CRT sets, and there are so many settings, so many tweaks and so many things you can adjust that I've literally spent so many hours in those service menu's I can recite them by heart, and on this panel, there's just... nothing.
It's hard for me to justify so much cost for only adjusting my greyscale [I can do the basics of color, tint, etc. myself, even though not as accurately, very close]. Could one of you calibrators explain to me why the cost of calibrating this set is so much higher than a tube CRT, despite having *SO* much less to calibrate? Shouldn't it cost less, or is there something I'm missing?
