Analog film photography and cameras

Open it if you don't think you have much to lose. There's a good place in Near Holborn. Camera City if you want to take it in though, they repaired a Yashica I had back a while ago. Good peoples.
I imagine your Ricoh is way way more advanced though and might be an electronic fault, so would come down to price of repair.

I opened it up last night but only really took the bottom of it off, not really sure how to get the rest apart but may give it a try.

Does it make a clicking noise?
Ricoh would've repaired shutter problems by replacing the whole shutter unit and lens but they don't do the GR1 any more.

Yup, exactly this. I'll get a video of it as soon as I get home.
