SOLVED! D750 (apparently) failing to go to sleep

[Akira]

Hello,

Yesterday I noticed that my D750 failed to go into the sleep mode.  When I noticed I had forgotten to switch it off, the camera body (and even the attached Kirk plate!) was warm, and the remaining power of the fully charged battery had gone to 20%.

The power off times for the monitor are all set to less than 1 minutes except for 10 minutes for the live view display.  However, the live view was off when the above mentioned problem emerged.

In order to make sure if the problem can be reproducible, I intentionally left the camera switched on.  Sure enough, the camera is warm again after around 20-30 minutes.  The fully charged battery had only 67% of its remaining power.

I did have forgot to turn this very camera of mine off before, but never had the warming problem.

Have any D750 owners experienced similar problem?

i think it happened to me once also on other cameras

Rick, thanks for the reply.  Which camera body it was, and was the problem solved in any way?

My Df developed a similar problem by never turning off, even though the power switch was set to Off. Quite frustrating and effectively killing batteries. Nikon initially charged me for the repair, that was quite expensive around $500. After a few rounds of discussion with my Nikon Nordic contacts I had the repair covered under some kind of 'good-will' warranty. The camera was less than 2 years old.

The issue apparently is the sliding metal contacts under the On/Off switch that develop intermittent contact breaks. I have a lingering suspicion this is yet another problem caused by the new kind of materials (carbon-fibre or thermoplastic or whatever) used in the latest generation of Nikons.

Bjørn, thanks for sharing your experience.

My D750 is well within its warranty, but your reasoning is not something I hope to be true.    I will take mine to Nikon service if the problem persists.

Mine happened once and never happened again
send it to ginza for repair!

I just turned my D750 on and leave 20-30 minutes to see if the problem persists.  I will definitely take it to Ginza, NOT Shinjuku!

Check to see if anything is keeping it awake. Stuck buttons, levers half way between positions, or something similar. Inspect where the grip plugs into it and make sure nothing is bridging the contacts. Maybe try a different lens or no lens mounted and no memory card inserted and see if the problem persists.

Charlie, thanks for the suggestion.

I just noticed that the "Standby time" (menu item C2) was set to "no limit", which prevented the camera to go into the standby mode. 

I think I set it to "no limit" when I was shooting the light trails of the train and wanted the camera to stay on while I was waiting for the shutter chances.  I reset it to its default value (6 sec.).

Thank you all for your replies and suggestions.   I'm very sorry for your bother.

You saved yourself the trouble of sending the camera to nikon and a possible fix for others experiencing the same problem, so nothing to be sorry about

I fully agree.  Moreover, the rest of us (well me anyway) will now know to check out what the default settings on our cameras have migrated to over time should our cameras do as Akira's did (or indeed show any other unexpected behaviours).

Børge and Hugh, thanks for kind words.  I'm glad my absent-minded problem turned out to be of some help.
