Hi all
I have been trying to calibrate my 4000G Ampro for correct gray scale and color using Kal's guide and help from here
I got a cheap spyder off ebay and used HCFR ver. 2.1. Now my pj had great color until the amp card on the blue tube went south about 1 month ago. Curt sent me another one. Since I changed it, I can't seem to get a nice picture. Everyone has a red face and the whites have a pink tint to them. Now, I manage to do a great gray scale setup using the probe, guide and HCFR. All except 0 IRE have a deltaE under 10 with 6 of the readings under 3. I set it up for + - 13 ftL at 100 IRE. Visually, using Avia, DVD essential and HD and AVSHD, all look great. I don't think I ever had such a linear gray scale. Unfortunately, that is it. I f I only wanted to watch a test disk, this would be great. I did not perform the primaries or secondaries test since I can't adjust them anyway.
I realize the probe is not the greatest and have though about investing in an I1/2 unit. But what bugs me is the gray scale looks great. What will another probe do to correct color. And why was it right before replacing the amp card and now, I cant get anywhere near what I had before? What am I doing wrong?
