Screen is blank just the green light up buttons around it stays on

Product Name: WorkCentre 7830/7835/7845/7855
Operating System: Windows 10

All the buttons that turn green are stay on when the machine is turned on but the screen is blank. What could I try to get it working.

Hi,

The SD card on the SBC PWB (Main Board) is defective and must be replaced.
