Problems

• Check the display pin connector, clean it, rework or re-solder it if necessary.
• Check the capacitors and coils, replace if necessary, and then check the VBAT voltage and the VIO voltage on it. Those are the supply voltages for the display
• Check the two DSI line choke filters.
• If those parts above already checked and seems nothing wrong, the problem possibly exists on the Display UI chip. Reworking or replacing it will only fix the display problem.
