Bro, I posted a similar problem in the ps4 thread years ago, it unfortunately affects my DQ LE. I finally understood what went wrong after I disassembled my unit, and saw with my own eyes how a manufacturing overlook could lead to such a potentially avoidable defect.

Underneath your PS4, there are several fins. The most central fin is located directly below the eject sensor board. The fin occasionally may touch the eject sensor, and that would cause the eject state to be constantly active.

Some would say the eject sensor is activated due to dust, or static, I'm not too sure about that. But everyone will conclusively agree that but putting a tape on the eject sensor, problem solved for good. That would also meant you cannot manually eject the disc anymore.
