Troubleshooting - Polaroid 636 Repair Manual

SECTION 5 - MODEL 636 CAMERA TROUBLESHOOTING
Introduction
Before performing the troubleshooting procedures presented in this section, you should be
thoroughly familiar with the Theory/Sequence portion of this
manual. Quite obviously you must know how the 636 Camera works before you can start to
diagnose its problems.
Initial Inspection
The following procedure should be done before you get involved in an operational check of
the 636 Camera. Before long, you will find this procedure becomes automatic and you will
no longer have to refer to it for step-by-step guidance.
1. Visual
a. Inspect the camera for obvious faults such as gaps between body parts; and missing,
broken, distorted, scratched or otherwise defective parts. Pay particular attention to
lens, viewfinder and flash shield components for signs of smudges and foreign
matter. Examine the camera for cosmetic defects which are beyond allowable
standards.
b. Look into the lens. The shutter blades should be closed.
c. Look at the Counter window. With no film in the Camera the window should be
blank, indicating that the Counter has reset.
2. Pre-Operational
a. With the strobe closed, press the S10 button. It should not move, being held out by
the interlock tab on the strobe housing.
b. Erect and then close the strobe. It should move through its entire travel freely with
no binding. Also, when the strobe is erected and the camera is tilted forward, the
strobe should not fall forward.
c. Move the lighten/darken control tab from full-light to full-dark and then back to its
nominal detent position. It should move freely with no binding during its travel.
d. Press the front door release button. It should offer some resistance to thumb
pressure. At the forward end of its travel, the release button should drop the front
door open. Close the front door to be certain it latches properly.
