FS7 Magenta - Green shading problem?? RE-POST at DVinfo.net

Hello All ~

This is a re-post as I posted it in the wrong forum.

A colleague of mine just dropped in with his FS7 to load a few LUTs to try out. Lo and behold when the camera was turned on the picture exhibited a nasty strong Magenta to Green cast going from left to right right across the entire screen, it also stretched from top to bottom. Reminded me of some of the old shading issues we used to have with tube cameras and the early CCD cameras that had analogue circuits for shading adjustments.

Regardless of what we did. We did the following, Black balance, Switching between Standard to Custom to Log modes, powering down removing the battery and powering back up, switching modes from 50Hz to 60Hz and back again plus a total factory reset. Tried with and without lens plus tried different lenses. All to no avail. This FS7 still exhibited this nasty L-R Magenta / Green cast. Which became increasingly bad as gain was applied.

A bit of urgency required here as he is due to head to S.E. Asia for three weeks shooting. Anyone seen this problem on an FS7? Or any other late model Sony for that matter. If so what was the problem and what was the fix? Does anyone know? Any suggestions as to a solution would also be keenly listened to.

Monday tomorrow here so the camera is going straight back in to Sony for a quick fix hopefully. The camera is only three weeks old so still under warranty luckily.
