Well to put this concern into perspective. Don't panic. I have flown with a Bomb EVF as both carry on and checked luggage into and out of LAX at least 8 times this summer and have had no problems with TSA at all. My advice is to not hide the EVF, not gaffer tape or sand off the "Bomb" letters... just present it as normal carry on luggage and if asked what it is tell them that it is an an electronic viewfinder for a camera. i.e tell the truth.
Security teams are trained to look for the unusual, not the obvious. They may swab it to test for explosives but they do that to electronics anyway.
