Have a VSX 43 Elite. w/ same issue. ( Blue flashing HDMI light). Unplugged receiver power cord. Plugged it back in and pressed the Power and Advanced Surround button together for 5 seconds Same issue. Tried the same maneuver 3 - 4 times and it came back up and worked but with crackling sound through the center channel speaker. This finally went away, about 10 - 15 seconds and now it works fine. Will see how it works the the next time. Not sure why this worked but it did. Like others, think it might also be an HDMI cable issue. Hope this helps.
