My Eurov*x is completly dead when you plug it in to the mains but if i plug my computer into it and open up dnupman and hit download the box comes to life with channel number on front. When i hit start to flash it the download fails. It comes up dnld (which should be flashing on box) half way through then disappears again. When i unplug computer the eurov*x is working but as soon as the power is turned off the box goes dead again and will only come back on if i plug computer into it and open dnupman. Anyone any idea how to fix this? Would it be best to restore to factory settings and reflash? Any info appreciated
