following tips may help you to determine if possible
accidental damage has occurred.
Impact Damage:
Impact damage is often the most difficult to detect. The plastic
covers used on today's cameras do not dent like the older style
metal covers. They are much more resilient and will compress,
which causes damage to internal components, then return to their
original form. Look for cracks, abrasions, and gouges on the
outside covers. If the covers are separated at the seams, it
has been impacted or compressed, which causes the covers to pop
apart.
With zoom compact cameras, if the zoom lens is
sluggish in its operation or stuck in any position,
it has been impacted or compressed, which jams
the zoom mechanism. Also, if you hear a clicking
noise when zooming the camera , the viewfinder
doesn't zoom, or the viewfinder is jumpy when zooming,
this also means that the camera has been impacted.
Symptoms and/or Failure:
Impact damage can cause any type of malfunction, either mechanical
or electrical or both.
Water Damage:
Water damage is often difficult to detect with an exterior examination
because the water may have been wiped away or the moisture may
have evaporated. However, because it is detectable on any material
that oxidizes or rusts, check the screw heads on the exterior of
the camera for any discoloration or visible rust. Also, check for
any water spots inside the film chamber of the camera, on lens
surfaces, behind viewfinder cover windows, etc. Oxidation and/or
rust may also be found on the battery contacts inside the battery
chamber.
Fresh water damage is more difficult to detect
because it can take up to two months to oxidize
components before failure in operation occurs.
However, any severe water damage will usually immediately
render the camera completely inoperable. Salt water
is much more damaging and creates much faster oxidation
and rust.
Symptoms and/or Failure:
Water can cause any type of malfunction, either mechanical or electrical.
However, electrical malfunctions are usually the first symptoms
to show up.
Liquid Damage:
Liquid damage is differentiated from water damage because the substances
that cause this type of damage can be many, including oil, milk,
soda pop, juice, etc. Any sugar-based product will leave moving
components sluggish or stuck in a given position. Check all switches,
levers, buttons, hinges, or covers for any remnants of dried liquid.
With zoom compact cameras, check the automatic lens covers.
Symptoms and/or Failure:
Liquid can cause any type of malfunction, either mechanical or
electrical.
Battery Leakage:
Damage caused by battery leakage is fairly easy to detect because
it is visible. Check inside the battery chamber for corrosion on
the battery contacts. If corrosion is evident, this may interrupt
the power supply. Fresh leakage may leave a sticky wet residue
inside the battery chamber, which may ultimately damage circuitry.
Symptoms and/or Failure:
Like any liquid damage, battery leakage may cause mechanical or
electrical malfunctions.
Sand/Dirt Damage:
Sand/dirt damage is usually the easiest to detect because it is
the most visible. Check for grains of sand or dirt in exterior
seams, covers or around switches. Also check inside the back
cover of the camera in the film chamber area and around the seals
of the back cover. With zoom compact cameras, check inside the
zoom lens assembly by opening the back cover and looking inside
the zoom lens assembly itself. If possible, zoom the lens to
its full extension. Check for any sand/dirt particles.
Symptoms and/or Failure:
Sand/dirt can cause jamming of the shutter, film transport mechanism,
and/or zoom mechanism. Any moving operation of a product can
be affected by sand/dirt damage and this causes specifically
mechanical failures. |
