@ Guy Kuo and others...green tint (1 Viewer)

[Anthony V]

Set-up

Sharp XVZ-9000E
Denon 3800 via YUV
Stewart Firehawk 110'' diag.

Problem:
Slightly green tint on faces

Dear all

I have calibrated with AVIA and color bars are good.
When looking at the color-bars through the blue filter everything seems fine.
Checking the test-pattern with the 3 colors and % I have following results:

Blue 0 to +5%
Green -5%
Red 0 to 5%

So it looks pretty close to what is possible.

Strangely enough I still have a slight greenish tint with flesh-tones.
Where or what do I have to change to correct this problem ??
Gamma ?
Even when using Gamma Standard that has a flat curve the problem persists........
Would accessing the service-menu and changing the gains have an effect ?

I have my settings here as a reference in case some Sharp users whant to add their comments.

R Bright 128
G Bright 128
B Bright 128
R Gain 104
G Gain 95
B Gain 97
In the User Menu
Contrast: +3
Brightness: +1
Color: +4
Tint:+3
Red:+2
Blue:-1
Gamma 1
Col Temp -2
800 Ansi Mode

Maybe having the Color at +4 is a mistake an pronounces the greenish tint having to go to +3 with TINT ?

I know it's all question of personal taste but is there a general rule not to exceed Color 0 ???
What is the starting point ?
By choosing Color +-XX I then can compensate with tint +-XX so .....
BTW choosing Color +1 as a starting point and then changing TINT still will give me the greenish look....
Taking the color value lower than 0 will result in a lack of color and "punch"

Is this something that can be corrected with the projector settings or will I need some sort of a filter to compensate the green tint ?

PLEASE HELP

Thanks

PS: Sorry 1 post and already too many questions

If your image is green add red and blue. The 9000 (as you know) has separate red and blue controls. Use a gray step pattern to do this, then adjust the color and tint controls.

You may want to also try adjusting the color temp control. The last 9000 that I calibrated had to be moved to its lowest setting (-3??) then I had to add a lot of red to adjust the gray scale. Overall the projector looked great and is on my short list for a projector for my new HT room.

Hope this helped.

Regards
Gregg

@Gregg

Hello and thank you for your input.
Lowering colortemp to -3 ?
Do you remember how the settings where for red and blue in the "normal" menu ?

Red +30 ? where did you set Blue ?

Thanks

I dont remember the #s. I know I set the color temp at its lowest setting and then had to add a HUGE amount of red and take away a little bit of blue.

REMEMBER THAT EVERY PROJECTOR IS DIFFERENT

best of luck!!
