Yesterday, my Hitachi 57S500, only 18 months old crapped out. I have the Sears extended service agreement and advised them I lost confidence in the TV and did not want it repaired. They took it back and today I chose the above Wega. Given the suddenness of my buying decision (spent 3 months researching before I bought the Hitachi) I am wondering if anyone can give me any general info about tweaking, set up, etc of this unit. What are its strong and weak points and would calibration help with this type of unit? Any info would be great. Thanks.
