Had Chad from HDTVbyChadB come to my house last evening and calibrate my 735U. I couldn't be happier. After countless calls to Sharp, repairs from Sharp that did nothing, Chad was able to come out and just hook this thing up.
I've never had a tv calibrated in the past and was skeptical about it's success, but so worth it. Worth the additional money and worth waiting for Chad to do it. He spent about 4 hours here and explained every step that he was taking and what he was looking for in the final settings. Professional throughout and easy to work with considering my wife and I still play favoritism to the bright colors of a showroom tv - although not as bright as this tv was putting out in Dynamic mode.
Definately worth a call to have Chad out at your place if you're having similar issues - I'll be recommending him to everyone I speak to.
