Panasonic DMW-FL360L flashgun not firing, blinking Self Check and Test/Reset lights even after replacing batteries

Question

My Panasonic DMW-FL360L has stopped working. I get the blinking Auto Check and Test/Charge lights, which normally indicate that the batteries are depleted; however, even after installing a fully-charged set of batteries, I still get the blinking lights and the flash will not fire. The zoom head on the flash also will not move.

Is there a way I can fix this without having to send the flashgun in for repair?

(The same steps should also apply to the Olympus FL-600R, which is functionally identical.)

Follow these steps to soft-reset the flash unit:

Ensure that charged batteries are installed and that the unit is off.
While holding the Test/Charge and Back Light buttons, press On/Off to turn the unit on, then release all buttons. D DEL will appear on the screen.
Press OK. The Auto Check light will blink three times.
Press On/Off to turn the unit off, then turn it back on again. The flash should now operate normally.

If this still doesn't work, you may need to contact Panasonic support for repair.
