Flash sync repair, Multi Shot
A flash sync repair requires a total disassembly of the digital back. The integrated circuit which controls the flash output located on the link board is replaced.
Before assembly of the digital back, additional hardware modifications are conducted if necessary to insure the best possible performance for the specific product.
After a piezo element calibration and a CCD-sensor calibration, the CCD and the IR-filter is cleaned, and the filter is re-mounted (or replaced if it has any scratches).
For further details, please refer to the descriptions of “piezo calibration” and “CCD cleaning”.
After passing all tests, the back is ready to leave the workshop again.
