TJC HMI 2.8inch red screen SYS ERROR!

Hi, on one of my 2.8inch TJC HMI’s the winbond 25Q32 memory chip was physically damaged, so I ordered some new memory chip, copied the memory contents of the chip from the working 2.8inch TJC HMI to the new memory and soldered to other HMI board, after inserting the SD card everything is OK, the project is copied from the SD card to HMI and verification is OK, unfortunately after removing the card and reconnecting the power supply, all I can see on the HMI is a red screen and SYS ERROR!
did any of you have such a problem or know if it can be brought back to life??

Problem fixed!

Hi @Elektronik.pcb,

Glad you got rid of the issue. Since obviously no one else knew the solution it would be great if you could share it.
