Hey Guys.
I recently got this great synth, but when i turn on the power, it gives this.. Pixelated center stuff..
It worked before i got it from the previous owner, but when i turn it on i get this pixels in the center of the screen, making it impossible to see anything.
I must admit i did not try to factory reset yet, only reload the OS, wich did not solve the issue.
It "looks" like a software problem, or connection issue, and not a hardware issue.
Can someone give some good advice here? 
Big thx!
