IBARA PCB picture is fu*ked up

[Xeno]

Inspired by the IBARA topic I put IBARA on to my cabinet, but...

When it started the picture was flawed and had black bar on the top of the screen and was really unplayable, after waiting a bit for my camera to recharge the black bar disappeared and the picture became almost normalized, but there is still some flaws especially if I fly the plane to either far side of the screen. What might be wrong with it? I have never experienced this with any of my games, and fe Ketsui works just fine.

I don't know what's wrong with it but in hoping for the best, try taking it into service mode and reset the screen positioning.
