Warning: The flash capacitors located under the front grip contain dangerous amounts of stored charge and will need to be safely discharged before removing the motherboard. Use a Capacitor Discharging Tool to do so.
The motherboard is crucial for the function of both the software and hardware of the Sony a6500 camera; its failure will result in an inoperable device. If your camera is failing to turn on despite having a functional battery, the motherboard may need replacing. This guide will walk you through the replacement of the motherboard; it requires more steps than the other guides because it is embedded deep inside the camera. This guide will require opening tools, spudger, tweezers, JIS 0 screwdriver, JIS 00 screwdriver, and JIS 000 screwdriver.
