Absolutely. No lights and no reaction. (I tried briefly.)

OK, I can find out about that.


So it would assume I had started in Z1-3 (my season)? So if a Z6-D gate
had been off, I would have only paid £1 to get out in Z4, since it would
have assumed I came in in Z1-3?

On the way back you'd need to put £2.00 for the cost of two
extensions (assuming you have 1 - 2)

Oh yeah, getting back would not be a problem - I mean the extension
calculator didn't know where I got on in this case, so I am just
wondering how it would guess where I got on (and what it would guess).

I've given up assuming anything about what Oyster cards might guess. If
you go to a ticket office and get your journey resolved, you can tell
them where and why you couldn't validate the start of your journey and
they ought to accept your word for it.
I imagine you've used your Oyster since Saturday, so how much did you
have to pay?
