Purple Vertical line on Sony F-900???

[Mikael Lindström]

Were shooting a feature with two Sony F-900´s, and discovered a thin blue/purple vertical line across the frame in the lefthand side on one camera. It is most visible in the lowkey areas, dark greys and blacks. It´s been increasing over time, starting on an exterior day with temperatures below 0 degrees celsius. And very humid. Its both on the monitor and the tape. Were using Digiprimes and both types of the Miranda, Accuscene and Astros. Blackbalance is carried out regularly, and where using 5 different scenefiles. The material is still Ok to use according to the postproductioncompany and the camera has been sent for checkup. Just wonder if you have any ideas or experience in this matter???? Thanks a lot in advance.

I now know what caused the vertical line. Very rarley screws holding the electronic part of the CCD´s becomes dislocated and you get shortcuts in the circuits. Especially when its very humid. Sony Denmark, they once before had the same experience, had to hit the camera in order to recreate the problem. Loose screws around the CCD´s and a lot of humid is causing the problem. It is now solved and the material filmed is OK. Problem solved.

Thanks for keeping us informed.

Sony Denmark set an excellent example with they way they have supported HD in the region.

A creative business approach that helps the end user.
