Further to yesterday's neepery

In "Day of Evil" the failsafe panel is on the wall to the left of the door. I'm reasonably sure it isn't usually apparent there either, except when required for plot purposes.

(And in "Invaders", right after "Doomsday" in airing if not production order, the TV screen is back in place.)

[Yes, I'm home sick today. Antisocial cough and sniffles; not too bad otherwise.]
