M9 image fault

Mission Control, we have a problem.....note strange vertical dividing line through sky and image....Any theories? This is a non-processed image, i.e. this is how it appears on the camera's screen as well. Now happening on all my photos...Do Rolls Royces break down outside the showroom?

Serial numbers of cracked sensors and date/place of purchase may be useful in determining if the problem affected a batch of sensors or is more general. The same goes for failures in motherboards or any other kind of failure, like sudden death (like this: http://www.l-camera-forum.com/leica-forum/leica-m9-forum/138629-m9-non-functional.html ).

Ground Control to Major Tom - The reported issue is due to a difference in the gain of the output amplifiers of the image sensor, the mismatch can be due to a defect in the sensor or a drift in the power supply to the sensor. This issue can only be addressed by the crew at the Cape...

Dear Bert N and Jaapv, thank you for your diagnoses. M9 faults discolosed on this site are statistically insignificant, but I wonder about the overall situation, and if we would know, given the impact on sales of negative reports. Has the rush to meet demand impacted quality control? A conspiracy theory would make me feel better. After incredibly light use, and enormous cash outlay, I feel I should be given The Freedom of Solms for my lifetime, or several horses dying of exhaustion in their haste to bring me a replacement, on a velvet cushion, from that city....

I know nothing about elelctronics, having come from a Leica R6...I would be interested to know, though, if it is design or the quality of the components that leads to failure. I mean, I wonder how often motherboards fail in the cockpits of passenger jets...I suppose there is the issue of miniaturisation in the M9. I have to say, for all my complaining, that when it is working, it is a stunning little camera.

That is why aircraft have at least three computers running in tandem. And two pilots. The M9 has but one....

Jaap, We used to do all that with needle, ball, and airspeed.

It's a little of both, i.e, the design may have too narrow a margin for process variations and the process tolerance may be too wide to consistently yield spec-compliant sensors. Kodak's silicon foundry is relatively small compared to Sony's for example, and their process control may not be as tight as it should be. Then again, even with a well-controlled process, there will always be some defective parts, it may be that they are not screening their products as rigorously as they should and defective units are shipped. What this also suggests is that Leica is also not as stringent in their final acceptance tests as they should be. Aerospace components must go through strict qualification tests that consumer products would never pass.
