hi all. My 3 week old av700 won't turn on. It goes to the boot up screen, but turns itself off after a few seconds. Also, when I connect it to dc power, it goes to the boot up screen and stays there. Any suggestions on how I might fix this? Is there a reset button (I can't seem to find one). I don't want to send it back because I bought it from the USA (I am in Australia) but if that is what I have to do then so be it. Thanks in advance
