Customer Question

I've had the FL360L for two years and it sees occasional use. From time to time I've seen way over exposed or way under exposed images when taking a series of images with the flash. Today I was practicing portraits with the flash and different diffusers and angles and I was getting a lot of flash not firing (way under exposed result) or way over exposed.
Testing it with my camera (Later I show that it doesn't seem to behave correctly even with no camera)
I have the flash set to TTL A
The Flash responds on it's display when I change the zoom, e.g. The Zoom reading and the flash range numbers change in response to changing the zoom on the lens.
In the G7 I have:
Flash Mode - lighting bolt
Flash Synchro - 1st
Flash Adjust - 0 EV
Auto Exposure Comp - Off
Manual Flash Adjust - greyed out
Wireless - Off
Wireless Channel - greyed out
Taking even 10 images with nothing moved or touched on the tripod results in random fails. Even when I did not see the flash fire the image EXIF says the flash fired. My scene is clearly dark enough that flash should fire.
One interesting pattern does seem to occur. Often a no flash occurrence is immediately followed by an over exposed occurrence. In both cases the EXIF says the flash fired. I had seen this when I had set up 1 time lapse shots a while ago. In the middle of a long sequence of perfectly fine flash shots, a under exposed image followed by an over exposed image a minute later would occur. I figured it was something to do with the time lapse since the following images were ok and thus not the batteries so I dismissed it.
The problem happens in P mode or S modes
At first I thought it was the contacts between the flash and the hot shoe. Then I tried different sets of batteries.
Eventually I started testing just the flash without the camera.
On page 9 of the Flash manual it says:
4 Press the shutter button the rest of the way down to take the picture.
The unit emits light in proper exposure if [AUTO CHECK] lamp flashes
for approximately 5 seconds.
Suspicious Behavior with just the Flash by itself not on the camera or used with the camera.
If I press the test button while illuminated while holding the flash in my hand it may fire or it may not
If I press it two to three more times it may fire but it will usually stop firing after several presses EVEN THOUGH the test button is illuminated.
The flash recharges very fast so I don't see the test button go out. IF you put your hand around the sensor in the front the flash fires at full power and it takes two seconds for the test button to illuminate. I believe this demonstrates that the test button illuminates based on the flash being ready as this full power flash makes it take visible time for it to recover.
Once the test button stops firing the flash even though the button is illuminated, I have not yet found a way or an amount of time (May work again in a few seconds or not work again for at least 3 minutes or more) that will ensure that the next press will work. Turning the flash off and on doesn't make the test button actually fire it nor does removing and re-installing the batteries. Essentially I have no idea when it will ever flash again.
Based on my testing I can only conclude at the moment that "it's broken". I can't make it flash reliably when attached to the G7 or my GX7 where it exhibits the same behavior and the TEST button doesn't always make it fire even though it says it's ready (illuminated).

On this one Im afraid it needs service from a camera tech shop local to you if you have one. If not I can let you knwo where you can send it for this repair.

This one more than likely just has a bad shutter mechanism. This is kind of common on this model, but its a know issue so once it's fixed it should be fine for many years ;-)

How can it be be a shutter problem when the flash exhibits the problem with the test button even when not attached?
Customer: replied 4 months ago.
As per my description
Expert:  Michael replied 4 months ago.

Hi, the problem is that the shutter is remaining open longer than it should. That problem also causes the flash unit to malfunction as well. It's a timing issue.

Expert:  Michael replied 4 months ago.

The same circuit controls all of that;-)

I have been repairing cameras for over 35 years so I am sure of this.

Thank you
