good morning, I am a well experienced dishnet tech. recently had a 222k start resetting continuously i.e. start up screen for 5 sec, signal screen for 5 sec , black screen for 5 mins then start up screen again and repeats forever. did all the usual stuff and no success. it sounds like a power supply problem on the main board to me but , because these boxes are so cheap , I have never tried to fix one but am thinking about trying on this one. anyone have any idea what this problem might be specifically ? there are no cables hooked up except the video to the tv so its not a shorted cable anywhere.
