HELP Nikon D7200 can not REC video

[ullises]

Hello

I have a new Nikon D7200 + Sigma 18-35mm f1.8 Art + Sigma 50-150mm f2.8 HSM EX DC II

all is right but when I switch to video mode and press LV, nothing happens when I press REC button (red).

With any of the lens and with any of my cards

Sandisk SDXC I 64 GB 95MB/s (U3 10) or
Lexar Professional SDXC II 64 GB 150MB/s (U3 10)

Any idea about it?

THANKS
