I apologize for the hieroglyphics with which you have been responded to thus far.

Offset = bias = cutoff = brightness/black level for the individual colors(R,G,B) comprising the low end of the grayscale. Use b&w test patterns and instrumentation to properly set.

See? I didn't have to grill you for make & model to be able to explain THAT to you. ;)

I think there may have been some questioning driven by the terseness of the original post.

I didn't detect any. I think he was looking for a simple straight answer - which hopefully I provided.

How familiar are you with the service menu of this TV? I personally wouldn't mess with it without a pretty good understanding of what you're doing. Assuming the "offset" controls you're talking about adjust the low-end greyscale, changing the values of these controls could affect a specific color temp preset (your display has 5 in the user menu), or they could change a global set of values upon which all the preset color temps are based.

This is why having the brand/model # of the TV is important - service menus are often quite cryptic and every manufacturer has a completely different approach to what they put into one and how they arrange it.

This is exactly why Ratman asked for more details. They may be master values for each control or they may be the values for one memory, or they might have some factory-only function. As I said, unless you have a SM manual in front of you, I wouldn't touch any of those - they're definitely NOT the white balance controls that D-6500 assumed they were.

For the OP, in the future if you provide more information up front it will help others here give you specific answers. As you've seen, less is not always better and may lead to you being given misinformation based on assumptions.

Thanks HogPilot,
The way one "asks" for help starts things off on a bad note. Then having to pull teeth to get info one post at a time can be frustrating.

I don't understand the "heiroglyphics" and "grilling" comments. Pretty straightforward to me. Respondants shouldn't have to pull teeth to provide help and accurate info.

I guess I should have just initially responded:
"If you have to ask... don't mess with them" ;)

Agreed. Most of us have learned just to ignore requests that don't have enough info rather than wasting our time trying to get it.

I wish that we could teach other techs the same thing. It happens on the technical listserves and forums just like here.

I guess we have different standards. :) For me, my desire to help someone is directly related to how much effort they are willing to put into being helped. Use of the imperative tense knocks that willingness down further. :(
