The 53D in video mode sometimes acts strangely. I presumably had pressed the wrong button when the screen image suddenly froze and could not be resuscitated back to life. There was nothing I could do, the camera was in a deep coma so to say. Even shutting off the camera (with the on-off switch) did not help, all I could to was removing the battery.
After the battery was replaced the camera was back to normal again.
Irritatingly, I could not reproduce the problem, though I tried several times. Therefore I do not know which series of key presses induce a coma-like state like this.
Does anyone recognize this problem? Any solutions (where is the WRONG button?)? This has happened twice now; I have had the camera for three month, taken just over 1400 pictures and shot 19 videos.
Thanks for your replies!
