[Fixen]

I don't want to renew this thread, but I don't understand how I can get red and green LED lights on together. I tried unplugging everything and leave it alone for a few minutes (that worked once or twice), turning it on and off, toying with the whole thing, but nothing works. I know this question has been asked many, many times on this forum, but can someone make a general enlightenment to my aching head?
