How do I fix the inbuilt flash which is not working
The inbuilt flash has stopped working, How do I identify and fix it?
Are you using bracketing mode (or HDR)? Have read that when using this mode the flash is fully disabled.
It may be either a faulty capacitor C901 (see p.2-2 of the service manual) that provides the voltage for the flash or perhaps it is a faulty flash unit (see p.2-4 part #65)
Here’s a link to the service manual for the camera.
You may have to contact a reputable, professional camera repair service or opt for using an external flash unit if dis-assembling the camera seems too daunting a task
