I've also attached a text file of the service menu walkthrough Zerog6 created from a message interchange with KJGarrison. I must warn you to be careful when going into the service menu. I take no responsibility in any screw ups that may happen. It's also prudent to jot down the original settings before making changes, so that you can revert back when needed.

After days and days of research we decided on the a750 for my dad's first HDTV. After I calibrated it using just AVIA, my dad and I were both very disappointed. blacks were crushed and there was a TERRIBLE pink hue to skin tones that I just couldn't get rid of that was bothering my dad constantly.

I used your settings, and the difference is night and day! My dad is now so excited about his new TV. It looks just stunning now, literally.

Thank you zerog!

EDIT: The settings I didn't touch are at 128, should the others be set to 128 also?

You can almost do everything within the regular user menu, so you really don't need to go in there unless you have a particular reason. The only reason I went in there was to adjust the "WB Movie" settings, which included the GAMMA settings to lessen the clouding I had. It greatly minimized it and it's barely noticeable.

If one looks in the HCFR data, one finds that 100% white has a Y luminance of 168.724 ftL, black was measured at 0.054 ftL, and by dividing the 100% value by the 0% value, one gets 3110:1.
