A-1 light meter stuck 'on'

After a fall the light meter on my A-1 just stays on. It feel on the shutter button/advance lever. In order to turn the meter off now i must turn it off with its switch on the left or leave it in the L position, in the A position the light meter is on(in the viewfinder) weather I press the shutter half way or not. How can I fix it?

Unscrew the retaining ring around the release button using a piece of leather of rubber (e.g. bike tyre hose). If it is too tight try using a pliers with flat jaws or a "flexi clamp" type of wrench. Pull the pin that sits underneath the button. When turning the camera on with the button and the pin removed, does the meter still come on? If not, check if the pin is bent and may jam. If it still does come on I would further disassemble the camera to get access to the actual switch.

 

I'm at work now but I'll check it when I get home. I dont think it gonna be bent though it landed on the ring that you turn not really the button.

So I took it apart but couldn't get the pin out(it wouldnt fall out and I don't have tweezers). I notice though it wasn't centered like yours, it was shifted towards the middle of the camera. A couple problems that i didn't mention were that it was hard to switch from av to tv and also to change the value with the wheel on the front. After 'prying' the main shaft back towards the film advance they have freed up but im still having the issue with the half press. Leaving the ring loose on the button seems to fix that though. I think the issue there is that the ring(where it was hit) is pushing down on the button slightly. I'll attach a picture. The disassembled photo is after I pried it over.
