Lumix GH4 automatic exposure setting not functioning, overexposed

Hi all,

Ran into a little setback this evening. While shooting, my GH4 and I got a little wet from a breaking wave on a coral bluff, and now will not function in automatic exposure mode. It is stuck on the lowest aperture of the lens attached and a shutter speed of 1/8, causing all shots to be vastly overexposed.

I can shoot normally in all other modes. Shooting manually, I can adjust aperture, shutter speed, ISO, etc. Sensor and lens is fine, and in manual, images result normally.

Has anyone encountered this problem? Could it just need a little dry time R&R?

I would not hesitate to take it into my local shop in Portland, Ore. for a look, however I am in Barbados for the month, so a little bit of a fish out of water (no pun intended).

Any help would be vastly appreciated.

In M, it seems that you can control f/stop, shutter speed and ISO. I guess that the parameter control set should have no problem.

Can you elaborate more on what automatic exposure mode you used? iA/iA+, P or S/A? Had you tried S (you set shutter speed) or A (you set f/stop) to see would your camera adjust the corresponding parameters accordingly? If so, you in-camera metering should work (accurate or not is another issue).

When your camera be frozen at wild open and 1/8", had you tried to switch off the camera? When power back on will do no good, take out the battery for a few seconds to see would it work? For the later scenario, I suspect that your camera might have certain internal problem (I had hardware lockup on G1 after a water accident caused serious erosion of the electronic parts inside).
