One of my E-PM1s has developed a very bad problem out of thin air. Took it out of the studio for a shoot and when I took a shot the screen would go completely blank and would not return to operating mode. If Rec Mode is on then it will show the playback then go black without going back to operating mode. If I press OK, then the camera will turn itself off. When turning on, it will also ask to set the Time/Date (like my other E-PM1 which loses the date setting as soon as it loses contact with the battery). I tried with Rec Mode off and on, so this has nothing to do with the playback. I tried a firmware update. I was on on v1.2, so I had an upgrade available to v1.3. The upgrade installed easily, but made no difference to this problem. Currently, I am leaving the camera with battery out in the hopes that it'll completely reset itself... but don't really expect that to do much. This is probably a hardware problem, I think. Has anybody else had this problem? I'd like to learn as much as I can before sending this camera off for repairs. As you all know, I am a very busy photographer and can't afford to be without my bodies for long. I am considering replacing it with an E-PM2, but need to watch the budget. I was eventually hoping to get an OM-D, but each of my cameras have a place in my setup and I can't replace my Minis except with another Mini or Lite. So they all must be in working order. Funny, my Minis have been my most problematic bodies ever (bad IBIS on one which was fixed by firmware update, inability to keep time on another which I just decided to live with, and now this...) but they are still my favorite darlings by design.
