ISF stand for Imaging Scienec Foundation whcih set the standard for TV calibration precedure. It will calibrate TV color to 6500k temperature which is the industry and studio stanadard for TV color temperature.

Cost is $299 which include:

Calibrate your TV to ISF standards by ISF-Certified Elite Service Specialists (Geek Squad)
Adjust the surround sound levels of the A/V receiver to ensure all the effect speakers are working optimally
Review and check the speaker system; verify that all speakers are properly positioned and working
Ensure that all wires and cables are neatly dressed, using wire ties as needed

I must admit that calibrating TV to ISF standard can make night and day difference in TV picture quality, but $299 sound kind of steep to me. I wonder how much they charge for TV calibration alone
