I was wondering if anyone knew how to adjust the grayscale in the service menu of this set. I can get into the SM but have no idea how to change it to 6500. Any help would be appreciated. The set also has some geometry issues but I can live with those but the set has way too much contrast. If I lower the setting it gets way too dark.

Greetings

Things like rgbcuts and drivers are in the service menu. These arethe grayscale controls.

Does anyone know exactly how to change the grayscale? This set has way too much contrast. Lowing the brightness and the contrast helps little and the Pic becomes way too dark. Any help would be appreciated.

Greetings

Adjust contrast in the service area first ... then do brightness ... then back to contrast then back to brightness ... etc ... interactive.

There is a disconnect in your statement though. What does altering grayscale have to do with it being too bright? the grayscale can be correct with the image too bright ... and conversely too dim ...

If I remember correctly,
you have to do the 480i Svideo gray scale before doing the other gray scales.

The problem is that the picture looks smoky in inside scenes. Like on nfl network HD studio shots in Miami or any inside shots. My Sony 36xs955 looks great with inside and outside scenes. Going down on my brightness and contrast helps some but it is still there. I have read in a few posts with folks that had had there set calibrated that the grayscale was over 10,000 and once it was corrected to 6500 the problem was corrected. I was hoping someone knew how to change that but I will most likely have to call for a ISF calibrator. Other then some geometry issues I love the set. The resolution is not as good as my Sony but I love the colors and it has a smoother silkier look that I like alot. Any help would be appreciated.

try turning the color down to zero then selecting the temp presets to the setting that looks the closest to bandwhite (probably std or warm...warm may look too red).

Having the brightness control too high will make the image look hazy (you have described it as smoky?). Turn it down to minimize this while not too far where you start to lose details in black.

Happy tweeking

I have the contrast at 29 and the brightness at 38. Any lower makes the PQ too dark and too much detail is lost in the shadows. Even at these settings many scenes still look smoky.
I contacted Chad and will probably schedule a calibration. I haven't had much luck on the forum on how make adjustments in the SM.
