Nextion 7" don't refresh


I just receive my NEXTION 7" display (NX8018K070).

I pluggedin on usb, and it work fine

I pluggedin on my FTDI and load my first program, and it work fine, without any problem

I plugged out and pluggedin, and now the screen not refreshing (see my attached file).

It's mean, that can interact with the screen, but I see my old page behind.

I upload now a blank program, and after the original ITEAD demo program, and the problem already here.

I buy a NEXTION 2,4" and upload program and it work fine, but the 7" not refeshing.

What can I do ?
