I have a few Nikon D90's and all of sudden 3 of them came up

Customer Question

I have a few Nikon D90's and all of sudden 3 of them came up with ERR messages. I only use the Nikon batteries and have a few to try to no avail . I've taken the lens off and cleaned the contacts. Changed memory cards. It sounds that as though the shutter sticks open and the photo is black. any suggestions. Tried 3 older backup D80's and they do the same thing. I did have to set the clock on those.
JA: Just to clarify, what's the exact make and model of your machine?
Customer: Did I lose you with that one
JA: What happened right before this popped up? What troubleshooting have you tried?
Customer: was shooting photos before that happened in each incident except the D80's. They don't really get used. Tried cleaning the lens contacts, change the battery from a camera that was working well and changed the memory card
JA: Anything else you want the camera expert to know before I connect you?
Customer: that's all I have at this time. All 3 went down today.

Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

If all cameras suddenly started showing the same symptoms, then there may be a common factor that affected them all on the same day.

Here are some factors:

- you could be wearing woolens, promoting a static-discharge-rich environment for the cameras. (Wool, when worn, generates static electricity in abundance, then when you touch a digital camera, its sensitive circuitry gets 'zapped', which can be quite bad for it, whether temporarily or permanently.) Or perhaps you were on a glass plate, or a vinyl sheet? those also generate static electricity and promote static discharge.

- were you operating the cameras in or subjected to, temperatures below 32 degrees F (freezing point) or above about 100 degrees F ?
- were they subjected to a humidity higher than 85 % or gotten wet ?
- were they operated in a gritty or sandy environment, such as a beach, a seaside, a construction site, or the like?

The first thing to try for these cameras: removing the batteries, and leaving them on a (dry, non-humid, non-dusty) shelf for overnight. Then put the batteries back in and try the camera(s) again.
