Nikon D90: Blinking err, no shutter

Wed, 05 May 2021 03:53:27 -0700

I found my old D90 and tried to take a few pictures but it doesn’t work.

Viewfinder is dark
Live View doesn’t turn on.
When half-press shutter-release (trigger autofocus) Err starts blinking. Goes away after a while.
When fill-press shutter-release I hear a motor buzz but nothing else happens, no AF, not shutter, nothing.

What might be the issue? Is it hard to fix?

Nikon D90: Why does my camera lens keep falling out

Sat, 16 Jan 2021 09:40:37 -0700

I have looked over Youtube and I haven’t found any solution that doesn’t involve buying replacement. We used this camera a few months ago and everything was fine. Then, now, I got it out and connected the lens and it dropped right out. If anyone knows a solution to this, it would be great.

Thu, 21 Nov 2019 04:56:30 -0700

A camera instructor changed the setting on my D90 so any overexposed areas would flash on each photo as I reviewed shots taken. Anyone know how to change this setting back so that it won't blink in a distracting manner?

Nikon D90: Focus screen latch not latching. Could I have flattened it out?

Wed, 18 Jul 2018 13:55:49 -0700

Changing focusing screen, old out, thin gold border shim is back in, new screen in. Latch wire goes down but I cannot get it to engage the latch and click back into place. I was using tweezers and not the specialty tool for this. I now feel like the latch does not protrude as much as it appears in images online.

Am I just not patient with it or could I have folded the latch down by pressing too hard trying to seat the wire with the tweezers?
