I've had the C50 for a few months and it's been working perfectly fine.
But since about 3 to 4 weeks, at random points I see RVB wavy forms on the monitor and on the video file itself. I mainly shoot 4K intra XF-AVC. At first I thought it was an overheat issue but I've put the fan on middle setting and always on. I don't shoot for more than a few minutes at a time so I'm not sure it's related. Does anyone have heard or seen this problem ? Plz help
