My Sony A7 just came back from the repair with a listing that this part was changed out: A1976128A — described as "MECHA DEVICE SERVICE". Any idea what it is? I'm guessing it's the sensor, but it's weirdly named... nothing else comes up on Google.

I would assume that it's "mechanical device service", and probably just an internal code for tracking the cost of the labor to do the service.

  • ah, thanks. it seems to be an eat shoots leaves quandary we figured it to be mechanical device service too, but thought it meant a "device service" that was mechanical, as opposed to a service on a "mechanical device". thanks much!
