Ty shutter mirror is stuck in the down position. How can I fix this.

Try this: Give the shutter button a few quick, hard pokes with your finger. Don't be shy, you've got to give it a few good jabs. This can get the mirror unstuck. It's helped me before...

Try this before spending money on anything:
Open the camera front and back: ie, take off the lens, open the back door.
With clean hands, put fingers in from both front and back.
VERY GENTLY slide the shutter curtain to the side, as it would do if the shutter release was working.

In my case, when I let go of the curtain, the whole situation resolved itself, the mirror went back up into position and the winder and release both started working again.

Hi jandklandry, Sounds as though the cushion the mirror hits on the up swing is tacky thus holding the mirror up. Maybe you can yourself fix it however, I would suggest sending it to Nikon for a complete CLA (Clean Lube Adjust). You have a nice camera allow Nikon to do it proud.

Your second curtain is not releasing the mirror to come down.
This happens with weak 2nd shutter curtain tension.
If the wind lever is stuck and the mirror does not come down then the mirror tension spring came off.

If the batteries are flat or missing you wont get LED's to light up and it will set itself to 125 naturally. I know as I have tried it. It could be that the shutter has got stuck on its way down and it is preventing the mirror from coming down as a result this is a mechanical issue, not battery related. The best way I found to release the mirror was to gently, really gently stroke the shutter nearest to the film down towards the groove it goes home in. Recommend a cotton budd so you don't damage the shutter leaves or get grease from your fingers on the movement. This should release the mirror. The next thing to do is try preventing the shutter getting stuck again by removing the bottom plate which will allow you access to the cogs for the shutter. it is tight in there and it is recommended by some that you remove some of the movement to see and clean them up. I did this but it is tricky and it involves winding on the camera and rocking parts out with itself. Not easy to do. The shutter cogs are brass (or look like it) and they may have old oil stuck inbetween the teeth which needs cleaning out with a tooth pick and then lubricate but not with WD40 which gets sticky with age. Use a cotton budd again with the lubricant on so you don't affect other sensitive parts around this section. Alternatively send the camera for a good service. I just had mine done, got it sorted with a warranty for 12 months to and cost me just £45. They cleaned everything up, new light seals and sorted issues common to this model of camera. The photos are instantly back to their best. Compare a good service to a series of wasted film with an inconsistent camera. Peace of mind too, it is worth it and so is the camera!

Sounds like the shutter or mirror assemble is damaged and needs repair. This is a major repair that a technician will need to preform.

carefully try to lower it manually, it's probably the rubber bumper got sticky and is holding the mirror up. if so, clean the mirror gently with alcohol. you may have to remove the bumper. us a tooth pick and carefully remove the rubber. your camera will still work without the bumper just fine.

Your shutter leavers are getting slow. They will fail soon, most likely the old grease is sticking. You can get a replacement body for $40 as repairs/cleaning will be $80+

This is a result of the linkage from the shutter release button being out of adjustment. It is a mechanical fault that can be repaired very easily.

Could be 1 of two things: 1. Mirror linkage failed. 2. Something is holding the mirror; sticky foam or the lubrication has dried out. Remove the lens, use slow shutter speed to release the shutter. While mirror is stuck in the up position, very gently pull down on the front edge of the mirror. If it frees up immediately it was stuck on the foam. Might be able to see a mark on edge of mirror from the foam. Hope this helps.
