Geeetech

Hi

I bought a spare control board GT2560 for my 3d printer which I also bought from official seller Geeetech. I'm am satisfied with it. It's a really good relationship between price and quality. So thanks once more.
I'm writing you because of this spare control board i just bought. It doesn't work. When i plug all wires to control board and turn on 3d printer nothing shows on the lcd dispay. I just get dark sqaures on the display. The other control board I have (original one that came with 3d printer works OK) shows the same dark squars, but just for 3-4 seconds, then shows 3d printers status as it should.
Can you please help me? Is the item broken?

Best regards

Hi,
