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
