Sony A7RM2 Repair
Sony ILCE-7RM2 Repair Service
This camera was dropped and reads “Camera Error” when the power turns on.
I was able to fix it by re-seating the sensor, it took about 3 hours to do it.
By the way, I found something interest.
The time/date backup battery is located behind the main circuit board.
This means that there’s no way to replace the internal backup battery by the user when the battery’s lifetime has reached.
We can replace the HDMI port, USB port, and the main circuit board.
