REPAIR MANUAL OF SAHIB PENTAX ES 1 (Product No. 23117) It is necessary to separate the defects caused in camera from ones in P.C, board pattern assembly To separate those defects, camera should be operated with a good P.C. board pattern assembly (0-T) after replacing the initial one If camera functions normally at AUTO with the good one, the initial one must be defective and should be replaced.
Checking procedure: we FARED Remove bates and POC board pattern assembly Set shutter dial ar AUTO Install £8 set ring or fens (at 18) toa mercury SEP EAE EET FREES Put connector adapter (I31T7R-1500--A3 nto tormentor (1800). heck each teeing! of Competitor {1500 from A to T with circuit tester putting is one nominal fo a camera (+ ground) and the other for each terminal on connector adaption as shown in 4. eh terming of Connector (15000 is called as shown in Fig. 5.
If each terminal shows the following results, camera should be normal. TERMINAL RESULTS each terminal does not show the above results, check lead wires or soldering or parts connecting to the defective terminal. Or sometimes, Connector (1500) itself maybe defective, therefore it might be checked with circuit tester after undersold lead wires if abnormal results are shown. Repair instructions A. Non-proper exposure at AUTO I. No electric current from power source. 2. Poor holding of magnet. 3.
