Hi, Yes I had the same issue and it was to do with the default contrast settings. Can you see anything at all when looking from the top of the screen?
I could see the following screen below..
If you press and hold button A for 2-3secs this will take you to the following screen..
Then press button A once.. On Checkup Wizard. And you should then be at this screen below. Then press the Left/Right buttons to adjust the contrast and follow the on screen commands. Don't forget to save the settings at the end.
