SONY NEX-3N intermittent shutter error issue

First use of the SONY NEX-3N camera usually shows shutter error and message to turn the camera off and back on again. After reboot camera works as expected until the shutter gets cold again or and will not move as quick as the driver expects it to.
Making videos is not affected as shutter does not move while movie is recorded.

I also think my problem is electrical. Did you take it space to fix?

Oooh, so the trick is to make a round of multi shots to make obturador warmer 🤔
It works for me at least
