Sadly, my SX-70 is a bit dead. I bought a new door hinge latch from a nice guy in the US, but before replacing it, I thought I’d test the camera itself as per this tutorial online, taping the door up.
The shutter firing was erratic, sometimes it would fire, sometimes not. It produced these images:
Not great 😦
I decided it wasn’t really worth fixing the door, as the camera didn’t seem to work anyway. Shame – still, I only paid about £40 for the whole lot overall, and it was gamble. Makes for a nice ornament now…
