My Hitachi 57F500 has the Red Push that I have rear a bunch on about on this site which has been very helpful, now I have to fix it. I bought it from Sears and part of the deal is you get one free cleaning and calibration in the first year. Question I have is if their "calibration" is worth a darn or not. I have visions of a refrig repair man coming and taking my TV apart and I probabley know more then they do about it. Also any good step by step instructions on the web for calibrating a Hitachi TV ?
