Hi there, anyone went through this?
It works perfectly but the screen of the interface is totally black all the time.
Seems like a broken screen right?
Is there any test I could do before trying to fix this? For example, updating firmware, or whatever?
I just bought this unit used on Ebay.
I don't know if it broke during the shipping or it is just something I should fix with configuration.
New device for me, any recommendations?
