Hi I own a Pioneer 141fd. I recently had it ISF calibrated by Chad Billheimer, who is out of OHIO. I live in WV, so he drove at least 4-5 hours to my house. He covers a wide area I believe. Anyways, he did a great job. Before calibration, on my videogames, they were way too bright. Especially horror video games like Dead Space. And by turning down the in game brightness it still should have been less bright. After calibration it was perfect. He calibrated one input for ISF mode (advanced mode off) day and night and auto, and another for ISF (advanced mode on) day and night and auto; but if you want all your inputs calibrated he will do that for the same price. Chad also calibrated my new surround sound system. He was thirty minutes early too on arriving and his prices are more than fair. So if you need your AV stuff calibrated I recommend Chad Billheimer.
