Nikon D90: Overexposed areas blink when reviewing photos

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: Replacing SD Slot on Nikon D90

Mon, 07 Dec 2015 14:54:59 -0700

Lock and eject mechanism not working, I don't see any foreign objects in the slot so I figured since the part is only $10-15 I'd replace it, do you have video or manual?

Many thanks

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.

there are connectors inside i tried to connect together and the bulb started working fine but the trigger spring stopped working. They won`t work at the same time. The flash will fire while it is closed and make some burning smell. Any help is much appreciated,

Nikon D90: The camera auto features not working

Mon, 29 May 2017 06:39:49 -0700

My Nikon D90 is basically rendered as a point/manual focus/shoot camera. Pictures get taken but NONE of the controls work. The autofocus does not work either.

First it started with just the button to recall the pictures then auto focus and then the rest of the buttons on the back stopped working.

Any help appreciated.

I tried new battery, charging again, removing sd card, replacing sd card, resetting.
