There are various levels of calibration. The simplest is to use a calibration Blu-Ray/DVD. It normally includes a series of calibration screens, along with some transparent filters. Using your televisions standard controls, you adjust sharpness, brightness, tint (viewing the screen through one of the transparent filters), etc.

If you are really serious about calibration you can have an ISF certified technician calibrate your TV. The advantages to this approach are:
1. They bring the calibration equipment which can cost well over $1K.
2. They can access the factory settings menu on the television which are much more precise than the standard user controls (brightness, tint, contrast ...). This is dependent upon the factory controls provided by the manufacturer.
The disadvantage, of course, is that there is a substantial cost. And if your display drifts, which is normal over time, then the process has to be repeated.
