If my camera is turned off for a while, and I power it up, the back LCD turns on but no text is displayed. The fan runs at full power. The LCD doesn't turn on. If I try to power down nothing happens and everything stays on. The camera only turns off if I disconnect the battery.
After all this happens, when I reconnect the battery and power the camera on it seems to start up without any problems. This first-time freeze up has been a problem for some time now on my camera, and I'm finally getting tired of it. I thought maybe the new firmware build would fix the problem, but it hasn't.
This problem is fairly intermittent enough that I can't determine the specific cause. Some days, it never happens. Today, and two days ago, it did happen.
