Garmin 965 turns off

Did you do a soft reset - Hold in power button until it turns off completely , then restart after say 20 secs.

Is it only the running activity? If so possibly do a reset settings on running activity from teh settings screen for teh activity. You will need to redo any data pages unless you have a backup of it, see note below on how to do a device drive backup.

When you says goes off after it is selected , is it the activity power save possible? if you take to long to press start

I’ve done all of this, but the problem persists. It’s with all activity related, as a watch it works fine 

What FW are you on.

Do you know how to copy back a Sport.fit file if I make one available via a dropbox link..

It helped someone else with a different issue on a RUN profile 

If you want to try send me a message 

So it affects all activities, not just Run?

Please send me, I’ll check with all the possibilities. Thanks in advance 

Ok send me a message from Garmin Forum then I can reply to it
