Issues Mamiya rz67 pro ii

Hello all, I'm having problems with my rz67 pro ii.

I've read the manual about 5 times now, and I'm very stressed.

I have replaced the battery.

1. AE prism doesn't show any signs of power.

2. Basic manual instructions don't work.

Everything is unattached from the body.

Collar is on white.

I put on the film back.

Removed dark slide.

I lower the mirror, I cock the lens to the green dot - it returns to red.

I set the lens in and turn the ring to lock it.

Set shutter to 400 or any setting.

Set to M.

CANNOT COCK THE LEVER - it's jammed.

When I set it to yellow emergency mode, it works. I can cock the lever in M mode and in the Regular mode and it fires.

AE prism finders are prone to break down without warning

The first thing to try is clean all the contacts

Then check that the "Battery Check" red light glows

Clean everything this morning, still no luck.

The red and orange lights are functional and the sound works but it seems some kind of electric error is happening elsewhere in the camera.

Bit the bullet and took it to a shop this morning, updates to come.
