There were no lights on the interface or within the refrigerator, indicating that it was dead. Unplug it, wait a few minutes, then plug it back in. The interface lights came on, but there were no interior lights, and after a while, the interface display began flashing . It looks that a main board failure is the most likely cause. Is it anything you can help with?
For proper functioning, the display board relies on the main control board; it receives the supply voltage but not the right signals. We can reassemble defective control board modules; go here for more information. https://www.upfix.com/product-category/appliances/refrigerator/
