So long story short I bought a 4520 refurb from Accessories4 less through Amazon two weeks ago.
I hooked it up in another room tonight to test it out before it goes in the theater later.
The red protection light was blinking as soon as i plugged it in. Disconnected surrounds first tried again, still blinking, turns on red solid after one push of the power button then turns on, seems ok then shuts off and the light blinks again.
Disconnected all of the speakers and tried it again. Same deal.
Disconnected everything (Hdmi's, network cable, sub) same deal.
Unplugged it then plugged it back in, now it turns on and stays on with nothing plugged in.
All items, hdmi, speakers etc are working fine in my Elite sc-35.
Any thoughts? I'm thinking of just returning it.
The biggest room in the world is the room for improvement
