Although I do not work with an HASSELBLAD H-System , but with HASSELBLAD V-SYSTEM + CFV-16 back , i am aware of the more complex nature of the H-SYSTEM .
If I get an error message of any kind on the digital back or during processing my digital files in FLEXCOLOR or PHOCUS (CFV-16) , I do know , only the digital back can be the culprit .
If I get the same , but using an H-SYSTEM , the culprit could very well be the
back , the camera body or even the interconnection between both of them .
If you can not reset the error situation by removing power or a possibly known reset procedure , you only have the chance to determine the culprit by , either replacing the body or the back , if you have the possibility to do so . Might even be , remove and reattach the lens .
But , as I mentioned before , as we do not have a list of possible error messages and a possible reaction to these messages by the user , the only chance we have is , either the experience of a guy in this forum , who experienced that situation before , or get the specialists in the boat and let them determine , whats wrong .
