Sony Service Company Service Bulletin National Technical Services A Division of Sony Electronics Inc. Park Ridge, New Jersey 07656 Computer Monitors CSI-111 Model: CPD-100ES, CPD-200ES No. 173 Subject: Front Panel Function Button is intermittent or Date: December 9, 1997 Function is Incorrect Symptom: (222) If, the front panel buttons, mainly the brightness and contrast buttons, are pressed, other functions are activated different from the one shown by the On Screen Display. This may be caused by the push buttons switch’s internal metal contact surfaces not being smooth. This irregular surface causes higher contact resistance giving incorrect push button signals. Solution: Then, please perform the following correction procedure. 1. To ensure all switches are properly formed, push each Brightness and Contrast button, FIRMLY, TEN times in succession. This will condition the switch electrical contact surface to improve contact resistance. Switch should operate properly for the life of the unit. 2. If irregular operation persists, repeat Step 1. 3. If irregular operation continues, then replace the switch(es) as required. See parts list below.

J4.02 is used to align the N3 chassis type computer monitors. Special procedures must be followed to initialize the monitor CPU. Alternate procedures are needed to edit the DDC (Display Data Channel) EDID (Extended Display Identification) data. Solution: Then, please use the instructions listed below in addition to following the procedures in the DAS User’s Manual Ver. J2.0. 1. The data files “200PS_MP.DAT” and “500PS_MP.DAT” must be copied from the DAS J4.02 install floppy disk to the DASJ402 subdirectory. This is in addition to the normal DAS J4.02 SW installation. Check for the data files “200PS_MP.DAT” and “500PS_MP.DAT” in the DASJ402 subdirectory. 2. If the data files “200PS_MP.DAT” and “500PS_MP.DAT” are not in the DASJ402 subdirectory, then install these files as follows. Put the DAS J4.02 Install Floppy Disk in the A:\ drive. Then type the command: “copy A:\*.dat C:\DASJ402” and press . 3. The DAS J4.02 program does not support the MPU initialization for the GDM­500PS and the GDM-200PS models. Use the “Write EEPROM File to Monitor” function instead. The files copied in Step 2 above will be used for initialization. Use the “Step by Step” functions to complete the alignment adjustments as needed. 4. DAS J4.02 cannot edit the EDID data in the N3 monitors. Other DDC instruments must be used to for this operation.

Loose Degauss Date: June 1, 1998 Coil Assembly Symptom: (143) If the Degauss operation is incorrect. This may be caused by a loose Degauss Coil Assembly. Oil used to inhibit rust may prevent adhesion between the Degauss Coil Holder and the CRT mounting frame assembly. Affected units consist of part of the production with the SN range below 4070016. Solution: Then, please perform the following procedure to position the Degauss Coil and to replace the (4) Degauss Coil Holders if required. NOTE: The following items (up 4 per unit) are needed to complete this procedure. REF DESCRIPTION PART NUMBER NA DEGAUSS COIL HOLDER 4-045-123-11 NA 12” NYLON CABLE TIES NA 1. Disassemble the unit to access the Degauss Coil assembly. 2. Locate the (4) Degauss Coil Holder locations. There are two at the top and two at the bottom areas of the CRT mounting frame assembly. Refer to the following illustration (Top Degauss Coil Holders Shown). 3. Inspect each Degauss Coil area to determine if the Degauss Coil Holder has become loose or displaced from the correct position. 4. Remove and discard any loose or detached Degauss Coil Holders. 5. Clean each mounting area of the CRT mounting frame assembly where a displaced holder had been attached. Use a mild solvent. Dry these areas thoroughly. 6. Install any required new holders to the CRT mounting frame assembly. 7. Carefully position the Degauss Coil assembly into the correct position in the holders. Adjust or replace any of the side tie wraps that are excessively tight. The side tie wraps should be snug but not tight. Refer to the following illustration. 8. Assemble the unit and verify correct Degauss Coil operation. Cont. Reference: SUA-CITL 98002, J.
