I bought a HS10 last December and recently began to calibrate it after reading many posts in this forum. I use a commercial lux meter (0.1 lux sensitivity) and dichroic filters to measure the three colors. I use 80IRE from the Avia dvd (played on an xp-30) and the low temperature settings to calibrate the meter. The original gain settings are R145, G 89, and B 72. I then add a cc20r optiflex filter and adjust the RGB gain and bias to R165, G150, B149 to get back the original RGB ratio at 30 and 80IRE. The pictures generally look good but black looks blue.
When I measure the contrast ratio using 0IRE and 100 IRE from the avia, I only get around 470. So I checked the contrast ratio for each color using the filters. The red is 550, green is 650, but the blue is only 280. Even when I crank the blue gain all the way up, I still only get around 320 (my picture contrast is 80). 0IRE looks distinctly blue. I remember reading a post saying he/she had contrast for all three channels above 600. Has anyone seen such a low contrast ratio for the blue channel before? Is there any adjustment to correct this problem? Or I have a defective LCD panel for the blue channel?
