Inspiron 24 5459 AIO intermittent black screen

Inspiron 24 5459 AIO has begun to intermittently go black:

  • duration: from 5 seconds up to "permanent" until reboot
  • computer is still working and functional
  • aux monitor on HDMI stays on and seems fine
  • All drivers updated today: problem persists.

If the external monitor connected to the rear HDMI out port always works, then the GPU and operating system driver is OK. Perhaps the internal ribbon cables that connect the LCD to the motherboard are loose? Here is the Service Manual.
