Hi everyone, sorry for late answer.
I think the problem is the screen because when i firt power on the device, i get the lower half of the screen working but the upper half is blinking with no image.
I dismount the screen bezel and it seem that there is some cracks in the pannel at the lower left corner (see image 1, the result is the same with the bezel don't mind the kapton tape).
After cleaning the zebra strips on both sides and pplaying with the position of the screen, i managed to get an almost complete display (image 2) but after 1 or 2 minutes without touching anything, it goes like on image one.
It's look like the hot bar attachement like in Dave's video 1192 have failed...
After all of that, given the fact that the device fall before been thrown to the dumpster make me think that the screen is broken.
Any advice to try fix it ?
Thanks for all your answers
Best regards
Baptiste
