Servicing - Sony DSC-S75 Training Manual

Servicing

The lens, including the mounted CCD assembly, is replaced as a unit. Except for the manual focus ring in the
front of the lens, no internal repairs are to be done to lens assembly.
? Error message E:61:00 or E:61:10 is usually an indication of a jammed lens assembly. Replace the lens.
? Shading (darker picture) on one side of the picture (usually the left side). This may be caused by a defective
lens. See ESI service bulletin E16561506 for additional information.
? After replacing a lens, a complete camera realignment is required.
? The lens design allows the technician to look into the lens and see if the iris, zoom and focus lenses are
moving. With experience, the technician can determine if the internal lens parts are moving properly. This is
best done when the unit is turned on and off while looking into the lens.
? Use an IR indicator card or laser power meter to check if the laser is working (go / no go). If it is working, the
laser light will go on in NightFraming mode when the shutter is pushed halfway down.
? The external focus ring can be repaired in case it falls off. Replace the three screws shown in the picture with
self locking types, part number 3-056-559-01. Alternately, you can add Lock-Tite™ on the original screws
and tighten them.
? Replacement lenses come without the laser flex board.
The original one must be removed from the old lens and
installed on the new one. This is very easily overlooked
and the camera is then returned to the customer in this
condition. Obviously, the low light features will not work.
See Figure 14-3
? To avoid ESD damage to the laser, use the precautions
outlined below.
Protecting Laser from ESD
•
The laser assembly is extremely sensitive to ESD
voltages and easily damaged by it. To avoid ESD
damage to a good laser LED, solder together the two
solder pads on the laser assembly before replacing,
handling or removing a good laser assembly. See figure
14-4.
? Make sure to remove the solder bridge once the laser
assembly is in the unit.
