GH4 failed to power up yesterday morning?

Panasonic battery was in the >80% charge state, .. took 15 minutes to fully recharge.

Meantime, I inserted the second fully charged battery, no change? .. no power light, .. dead?

The camera has had very little use since new, is in mint condition.

I had completed a short out-door still's shoot the previous day, .... viewed the images on it's screen then set it aside until the next morning. Picked the camera up to further view the shoot, .... "Dead"!

I removed the SD card, ... lens, battery, ... tried other SD cards and lenses, .... Dead.

Took it back to the shop, .. they rang Panasonic, ..... It's on it's way to the service center.

Has anybody experienced this problem with their GH4? .... Any Ideas?

I thank you in advance.

I had a similar problem with my GH3. Would not switch on with internal battery, but did power on with external battery in the battery grip. The circuit diagrams in the service manual show a protection diode in the internal battery power circuit, the power from the battery grip bypasses this diode. I suspect that there is another diode in the battery grip but I do not have a circuit diagram for the battery grip. I took the camera in for service, iirc the total cost was about €110, the bill stated a diode costing €1 was replaced.
