Ok Xavier, with your new lcd it's better but now the problem is with my usb key. I have to find another one because the new one that i use is no compatible !!
The cer40 is in good state and don't need to be replaced.
But however i will pay the one that y have sent me in case of future problem.
Thanks again for your precious help !

And for the spacer for the screen you can view the photo :
It's very nice from you to propose a screen, in regard of previous picture it seems that mine is out of order.
About MCU how can i know if it's ok ?
Thanks again Xavier.

Hi Xavier,
 
Have you tried powering it with a USB cable ?
Yes and same behaviour.

Does it play sound if you unplug the display ?
Yes you can listen "plop".

Can you enter bootloader ? Press a key while powering the preen.
Here the result :

Bootloader and Firmware updated successfuly but still blank screen :-(

The first screenshot looked like a blank screen.
This second one is different.

I need to know if the MCU works. Several solution:
. Does it make sound ? plug a keyboard or be sure that the boot sound is activated.
. Is it recognized as a midi device ?
. Does the squares on the display change when you press the menu button then back... (or any other keyboard/encoder manipulation).

No sound, i have tested every midi channel !
No change on the display when i use encoder.

I search for a new usb key next evening to test it whith a new one !
I will let you know asap.
