On my Bryston amps, I cover the green LEDs with a small piece of 3M blue tape (so it doesn't leave residue on the face plate) and then I put a small piece of electrical tape on top of the blue tape. I do not like the distracting big bright green or red

LEDs on while watching movies. All I want to see is the screen image. All this engineering negated by 3 cents worth of tape. I listened to my right to my left, in front and behind and all my speakers were "gone" - guess I shouldn't have covered those lights
