i have the samsung HCN5527w hi-def projection tv. i've had problems with it since i bought it. for instance, the DVI pic on 720p and 1080i looked green and the 480p looked much less sharper compared to the 480i. so the tech just replaced the digital panel in the back. at some point he was adjusting thr red, blue and green lines with a screen he made come up on the tv that was basically a big grid of white lines against a black background. i could see from where i was that boxes were all different sizes and uneven. he must have gotten lazy cuz after he split and i checked the pic with the THX optimizer i can clearly see the pic is warped. PLUS the color still tints to a light green on 720p and 1081 when using the DVI! does anyone know the code i can use to adjust the pic myself or where i can get it? also, what is the name of this test, meaning the grid of white lines to adjust the colors. THANKS!
