I'm bumping this to the top! I see a lot of posts mention "green" in a negative light wrt the 507, but not sure best way to fix it. Is the set simply set up green similar to red push from CRT RPTVs? Paraphrasing the comments I've read:
Green too vibrant (unnatural or fluorescent - check out the quidditch scene in Harry Potter or the picnic grass in AOTC)
Shadow greens (check out 24 on Fox or Reign of Fire)
Olive tint to flesh tones
Overwhelming green when green is the dominant color in the scene (Matrix or Mash re-run)
I know all are related, but does everybody agree that there is a green tint to an uncalibrated picture? Or do some sets tend to be red?
I had success in reducing mine by simply reducing green gain in the SM but did not know if this was the best way. I've read here (Tom R?) that you should start with the offsets then the gains to tweak it out. Also, it was suggested to reduce G gain by X (reduce till the vibrancy looks good) then increase the G gain back by 1/2X and increase the R and B gains by 1/4X to balance the color.
If you are seeing all of the above (and don't have CF!) can some of the experts here help out?
Is it correct to start with offsets? If so, what souce material would be a good choice?
Is the "down by X, up by1/2X........" described above still considered the best way to go on the gains? Is it best to use this type procedure on the offsets as well?
I found reducing the G gain was enough for me, but again, wasn't sure that I had done the best job of it. Right now it doesn't matter for me as my 507 is displaying the 3 blinking lights problem and is going back to Tweeters.
