If you are the insatiable "tweaker" and don't have a ton of money, and would rather "Hot Rod" your own TV than someone else... this is the guide for you.
This "Dummies and Cheapskate's Guide" is used to calibrate contrast, brightness, basic color, CIE color triangle calibration, greyscale tracking; all using the Service Menu. It allows you to calibrate the "Default" modes to correct CIE reference standards, allowing you to reset the calibrated defaults in the user menu, if someone changes the values. This also has the advantage of not having to change video settings after exiting the Service Menu (finally!)
You thought your picture looked good now...wait til it is calibrated to "Spot-on" CIE reference standards. It's like sitting in the theater again with perfect blacks, whites, skin tones, sky colors, etc.
Equipment will cost you less than $75 (Spyder2 probe and GetGray calibration DVD, Blue Filter) and a couple nights in a dark room. You will need a nearby computer or laptop to hook up the probe and possibly a USB extension cable.Service Menu Calibration for Dummies and Cheapskates
It was written for my HL-"S" 6188W and my future reference, but thought I'd share it with the other geek tweakers out there. I've read the Service Menu is similar for the HL-T version, so offer it in this forum for your perusal. Of course, if it's significantly different, it's up to you to use at your discretion.
Please heed legal disclaimer in the guide... you can inadvertantly cause problems to your television requiring an expensive "Professional" fix or void your warranty... yada, yada, yada, blah, blah, blah.
