Tekniskt sett inte alltid, i " Ett ojämförligt barn " introduceras vi till TARDIS och det verkar som att det är första tiden har kameleonkretsen misslyckats. Doktorn säger:
It's still a police box. Why hasn't it changed? Dear, dear, how very disturbing.
Det här konstaterar att TARDIS är fast som en polislåda, men Susan avslöjar att det inte alltid var en polislåda:
SUSAN: It should have changed. Wonder why it hasn't happened this time.
BARBARA: The ship, you mean?
SUSAN: Yes, it's been an Ionic column and a sedan chair.
BARBARA: Disguising itself wherever it goes.
SUSAN: Yes, that's right. But it hasn't happened this time. I wonder why not.
I serien " Attack of the Cybermen " ändras TARDIS flera gånger efter att doktorn försökt fixa kameleon krets. Först i en prydnadsdräkt, som beskrivs i skriptet nedan:
DOCTOR: This looks familiar.
PERI: Where are we?
DOCTOR: Scrap yard.
PERI: I didn't mean that. I meant, whereabouts on Earth are we?
DOCTOR: London.
PERI: It didn't change.
DOCTOR: Hmm?
PERI: I thought you said it was going to blend into its surroundings.
DOCTOR: Oh, she's probably thinking about it. Come on, let's find out where those signals are coming from.
(The Tardis changes into a highly ornamented dresser.)
PERI: Oh, neat, Doctor.
DOCTOR: Neat?
PERI: Very neat. I mean, there's nothing at all incongruous about that.
DOCTOR: Well, she hasn't done it for a long time. She's out of practice.
PERI: Of course, Doctor.
Här visas TARDIS i midtransformation och som sista byrå.

(The Tardis materialises in Lytton's junk yard as a small pedal pipe organ.)
DOCTOR: This is getting ridiculous.
PERI: I'm not saying a word.
DOCTOR: I was certain I'd fixed it.
(He pulls out a stop and plays the opening line from JS Bach's Toccata and Fugue in B Minor.)
Slutligen blir det till en grind.
(A pair of large wrought iron gates, the sort you'd find at the entrance to the driveway of a very large house, materialise in a corridor. The Cybermen lead their captives out.)
GRIFFITHS: What happened to the organ?
PERI: Do you really want to know? Oh, this place is so cold!
TARDIS visas också odödad i "silvergrå cylinder" på doktorns namn .
