I decided to test one of our HD100s at all gain levels to see where the split screen problem becomes apparent. It seems to me that it is most noticable in low IRE levels, even in +3dB. I adjusted the aperature on 0, +3, +6, +9 to make the split as visible as possible.
Since we go into production next month and both of our cameras present this problem, I spoke to my dealer about the problem and he called JVC Canada.
The engineers told him that they of course are aware of the issue, and were aware of it during the QC process. However, their tolerance for it is +18dB. Therefore if you are using +18dB gain and you see it, there isn't anything they can do.
However, I was told that if I saw it in other gain levels, I could bring the cameras in to JVC and the engineers would calibrate it within 24 hours or replace the whole camera.
The second problem was 1 blown pixel on one of the cameras. My dealer automatically told me to return the camera - they have a zero tolerance for bad pixels on this first run of the cameras. They will either mask it or replace the camera same day.
However, he did suggest that I try one thing. He had heard from another dealer that if you left the camera on for over two hours, it would self-mask the bad pixels. I tried it (you can see the still images for yourself) and it did nothing.
So, I am heading down to JVC on Tuesday with both cameras, and we'll see what happens.
