I have my computer set up through my onkyo, but recently it has had trouble picking it up and I end up getting a blue screenon my tv. I changed hdmi cords thinking I had a short, but it still does it. I can fix it, but I have to either power off the onkyo or unplug the hdmi from my puter then plug it back in, and that usually takes several attempts before it works. Anyone had similar problems? and if so are there any fixes?
