FP2 - Screen frozen in multi color pixel

Hello everyone,
Since yesterday I encounter display problems on my FP2.
It started flickering after each slide on the screen, then black screens.
And it quickly turned into a multicolour screen.
as below.

Now, no more except the multicolored display screen from time to time. The charging is working, the led is working,
I removed the battery: no change.
I removed the phone. I removed the screen, clean the connectors. no change.
I will contact the support, however if you have any solutions I’m interested.

Thank you in advance for your help.
