M9 problem

[raid]

OK Willie. I will do this tomorrow.

Get the thing in the mail and pull out your M8. It will come back like new.

With the correct firmware also.

I wonder if my insurance of the M9 covers such repair.

If the sensor circuitry failed (as jaapv suggested), this is a failure in the analog sensor section of the data stream. The SDHC card is not connected directly to the analog circuitry. In between the SDHC card contacts and the sensor electronics is the ADC and ISO analog gain components. While static electricity could do strange things when one inserts or removes the SDHC card, it is unlikely a SDHC card issue could damage the sensor circuitry. It would most likely affect the ADC (the last major component before the SDHC card).

The firmware would have to be corrupt in order for a firmware reload to have an effect. So what would corrupt the firmware? If it isn't too much trouble, reloading the firmware is worth it. After all every once and a while someone in a casino wins a slot machine jackpot, so low likelihood events do occur.

Correct me if I am wrong, so I format a memory card in the camera, followed by downloading the firmware to this card, followed by installing the card in the camera .... is this correct?
Also, which firmware version and from where?

Unfortunately I am not familiar with firmware procedures for Leica products.

My comments were based on decades of experience with scientific instrumentation (and more recently digital cameras) that used firmware (assembly language programing) for efficiency and proprietary reasons. If the original assembly language code is not flawed, it is extremely rare for the code to become corrupt. My advice was based on the minuscule chance that there is a bug in the firmware that rarely causes the sensor read out process to fail.

It appears to me to be quite pointless, but you can download the file from Leica's website, make sure that is unzipped to an .upd file, and place it in the root of the SD card, next to ( not in!!) the MISC map.

Insert the card in the camera (full battery), switch on and follow instructions on the LCD.

Thanks again, Jaap.
