Thank you Xavier.

Hi Xavier,
I checked all the points.
Everything is good. I wanted to tell you that I provoked a short circuit while mounting.
I soldered wrongly two points... they were unfortunately soldered together and I didn't notice that.
However, I melt the iron there and they were then fine.
Do you think that could have damaged the display?
Do you have any idea of what it could be now?
Thank you for your help.

Regards,
Maria

Hi Maria,

Except the display, everything is working fine ? the sound ? midi ? buttons, knobs ?

It's difficult to say if you diplay is damaged or if there is a soldering problem.
So this is your choice to buy a new display or not
