To calibrate LCD TV or Plasma TV you probably need to get the Colorvision SpyderTV. It looks like the regular Spyder but you also need a notebook PC to run the software to calibrate the TV. I think it cost $399 at Cathay Photo.
If too expensive you might try getting a DVD called Video Essentials. The DVD will show you how to calibrate both TV and Home Theater Audio using their test patterns/test tones. It also comes with a blue filter to adjust your TV with one of their test patterns. You might try looking for this DVD at Gramaphone or HMV.
