I just had Kevin Miller([email protected]; from Astoria, Queens, NY), an ISF certified tech at my house. He did a fantastic job and my new XBR400(36") looks great. The colors are perfect. I now see real pinks and yellows. The fleshtones are perfect as he and a colleague have figured out how to solve the "red push" that is prone to Sonys. I highly recommend him and having your XBR400 calibrated. It is money well spent. BTW--by connecting an HD100 to the XBR400 and sending a signal 480i to the component input, the DRC circuit still cuts in. It does not cut in if you send a signal via 480p or 1080i. Also--are just the XBR400's having the four sided black bar problem when receiving HD at 4:3 or are all tvs having this problem ?
