Windows 10: Black screen after three BSODs with different error codes

A Lenovo yoga 910, OS Windows 10, working fine until two days ago. It suddenly had three successive blue screens of death with the following error codes approximatelymemory managementkernel security check failurekmode exception not handledIt shut down and restarted by itself after each error. Then the screen went black and not recovered since. When it is turned on it sounds like it is busy doing things, but the screen remains black.I took it to a local repair shop where they checked the hardware and tried a bunch of things, i.e. hard reset, connecting to a monitor, switching to presentation
