LCD screen flickering and mid-print shut off. [ firmware: prusa3d_fw_MK3S_3_8_1_2869 ]

I took the x -axis apart and reassembled it with newly printed parts. After re-assembling and checking all cabling and connections, the Mk3s powers on with a flickring screen. Then, the flicker might go away and after having calibrated the printed and even re-uploaded the latest 3.8.1 firmware to make sure. Also, formatted the SD cards and tried to print the fan shroud for a test. The Printer would shut off at the exact same layer, somewhere in the first stages of printing after the first layer having been done. 

For now, problem solved by downgrading firmware one step back. to this one: prusa3d_fw_3_8_1_MK3S_1_0_6_MMU2S

Problem was with the prusa3d_fw_MK3S_3_8_1_2869.hex
