White Balance quandary

There I was, calibrating a Samsung HPT4264 display, which I own, which you will see shortly, is a good thing. Without remembering that most Samsung’s now have White Balance controls in the user menu, I jumped in to the service menu and commenced to white balance this puppy. I made the numbers look pretty good and I popped out of the service menu, took it out of Dynamic mode, a Samsung weirdizem I will never understand, and went on with my STB (soon to be) THX Certified Professional Video Calibration. As I proceeded, it dawned on me that there were WB controls in the user menu on Samsungs now. This is where it gets interesting, so move close to your computer to hear what happens next. I decided I could just use the user WB controls to do a little fine tuning. The more I adjusted, the more things got weird. I ran out of user controls before I could reach correct WB. This next part reminds me of the last words many Rednecks speak, “Hold my beer and watch this.” So I start working back and forth between the user WB controls and the service menu WB controls to dial it in and my post-cal report looked pretty good, but the display looks terrible. Skin tones are very blue. My guess is I need to put the service menu WB numbers back to their default and start over?? Bad news is, I recorded the user menu WB numbers in my pre-cal report. Did I mention that it was 2:00 am and I woke up and decided this would be a prefect time to continue pursuing my THX Certified Professional Video Calibration certification. I was wrong. So three questions, is returning the service menu WB numbers to their default the correct way to begin to fix this problem? Where might I find these numbers? ( I guess it would be safe to say that not all Samsung displays have the same default WB numbers) And my last question is why do they have WB controls in both menus and which one should we use. As Kelly McGillis said in the movie “Top Gun”, “I think this is a good demonstration of what not to do.” This whole thing will be a lot easier when we get electricity down here ……
