Jonwwww, looks like I have a problem as well. This unit was delivered last Thursday and it is indeed my first step into rear projection. I have the set in a dedicated room away from the kids. I went to buy the zenith silver sensor today so that I could watch football. TV usage will probably
be 75% dvd 25% hdtv/sports. Well, it seems that my power problems happen with a much greater frequency when the set is powered down on the antenna input. For example, I can turn on the set and see the blue light blink a few times, it will then turn solid and flash the channel number. Poof, the image will come and go and the blue light will start flashing again. I literally have to keep pressing the input button and switch to a different input. Sometimes I have to also have to turn the tv off when doing the previous step. Once, I hear from Hitachi I will post what they say.
