T470s / Error 0288 / Black screen / External monitor working

Hello everyone and thank you for this forum (and in advance sorry if my post does not correspond to its rules)!
My T470s worked well until I changed the screen (with a not compatible?). After that, a series of beeps rang at startup (code 0288 with Lenovo PC Diagnostics) and the screen remains black... I put back the original screen, changed the cable connecting the screen to the motherboard without any improvement. Today, I can still use the T470s but with an external display...
I'm sending you the bios dump in the hope that it gets corrupted.
Thank you in advance for your answers and repairs.

If the laptop is outputting an image on external monitor but not in screen itself you have a hardware fault not a bios problem.

Hello Vesko356,
Thank you for your answer. That's unfortunately what I was afraid: the change of motherboard to anticipate...
Sincerely
