SAFETY CHECK-OUT
(US Model only)
After correcting the original service problem, perform the fol­lowing safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly-sol­dered connections. Check the entire board surface for solder splashes and bridges.
2. Check the interboard wiring to ensure that no wires are “pinched” or contact high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps, and mounting hardware have been replaced. Be absolutely certain that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly tran­sistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement.
5. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement.
6. Check the line cords for cracks and abrasion. Recommend the replacement of any such line cord to the customer.
7. Check the B+ and HV to see if they are specified values. Make sure your instruments are accurate; be suspicious of your HV meter if sets always have low HV.
8. Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC Leakage. Check leakage as described below.
To Exposed Metal Parts on Set
AC
0.15 µF
1.5 k
Voltmeter (0.75 V)
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part hav­ing a return to chassis, must not exceed 0.5 mA (500 microampers). Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers’ instructions to use these instruments.
2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indica­tion is 0.75 V, so analog meters must have an accurate low­voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOMs that are suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suitable. (See Fig. A)
WARNING!! NEVER TURN ON THE POWER IN A CONDITION IN WHICH THE DEGAUSS COIL HAS BEEN REMOVED.

Getting Started
Warning on power connection
• Use an appropriate power cord for your local power supply.
For the customers in the U.S.A.
If you do not use the appropriate cord, this monitor will not conform to mandatory FCC standards.
Examples of plug types
• Before disconnecting the power cord, wait at least 30 seconds after turning off the power to allow the static electricity on the CRT display surface to discharge.
• After the power has been turned on, the CRT is demagnetized (degaussed) for about 3 seconds. This generates a strong magnetic field around the metal frame, which may affect the data stored on magnetic tapes and disks near the bezel. Place magnetic recording equipment, tapes and disks away from this monitor.
The outlet should be installed near the equipment and be easily accessible.
Precautions
Installation
• Prevent internal heat build-up by allowing adequate air circulation. Do not place the monitor on surfaces (rugs, blankets, etc.) or near materials (curtains, draperies) that may block the ventilation holes.
• Do not install the monitor near heat sources such as radiators or air ducts, or in a place subject to direct sunlight, excessive dust, mechanical vibration or shock.
• Do not place the monitor near equipment which generates magnetism, such as a transformer or high voltage power lines.
Maintenance
• Clean the cabinet, panel and controls with a soft cloth lightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent, such as alcohol or benzine.
• Do not rub, touch, or tap the surface of the screen with sharp or abrasive items such as a ballpoint pen or screwdriver. This type of contact may result in a scratched picture tube.
• Clean the screen with a soft cloth. If you use a glass cleaning liquid, do not use any type of cleaner containing an anti-static solution or similar additive as this may scratch the screen’s coating.
Transportation
When you transport this monitor for repair or shipment, use the original carton and packing materials.
Use of the Tilt-Swivel
With the tilt-swivel, this monitor can be adjusted to the desired angle within 180° horizontally and 20° vertically. To turn the monitor vertically and horizontally, hold it at the bottom with both hands as illustrated below.

You can set the delay time before the monitor enters the power saving mode using the OSD. Set the time according to “Setting the power saving delay time” on page 16.
Note
If no video signal is input to the monitor, the “NO INPUT SIGNAL” message (page 20) appears. After the delay time has passed, the power saving function automatically puts the monitor into the active-off mode and the u indicator lights up orange. Once the horizontal and vertical sync signals are detected, the monitor automatically resumes its normal operation mode.
Damper Wires
When viewing a white background, very thin horizontal lines may be visible on the screen as shown below. These lines are the shadows of the damper wires and are characteristic of CRTs that use aperture grilles. The wires are attached to the aperture grille on the inside of the Trinitron tube and prevent the vibration of the aperture grille.
Damper wires
Plug & Play
This monitor complies with the DDC1, DDC2B, DDC2AB and DDC2B+ Display Data Channel (DDC) standards of VESA. When a DDC1 host system is connected, the monitor synchronizes with the V. CLK in accordance with the VESA standards and outputs the EDID (Extended Display Identification Data) to the data line. When a DDC2B, DDC2AB or DDC2B+ host system is connected, the monitor automatically switches to the appropriate standard.
DDC is a trademark of the Video Electronics Standard Association.
Note
When using Windows
®
95, the DDC standard does not apply to the 5 BNC connectors. If you use the DDC standard, connect the HD15 connector to the computer with the supplied video signal cable.

• The screen is blank when the monitor is in power saving mode. Try pressing any key on the computer keyboard.
• Check that your computer power switch is in the “on” position.
• Check that the input select setting is correct.
• Check that the video signal cable is properly connected and all plugs are firmly seated in their sockets.
• Check that the 5 BNCs are connected in the correct order (from left to right: Red–Green– Blue–HD–VD) (page 6).
• Ensure that no pins are bent or pushed in the HD15 video input connector.
• Check that the video board is completely seated in the proper bus slot.
• Check that the video frequency range is within that specified for the monitor. Horizontal: 30 – 96 kHz, Vertical: 48 – 160 Hz Refer to your computer’s instruction manual to adjust the video frequency range.
• If you are using a video signal cable adapter, check that it is correct.
• See “Self-diagnosis Function” (page 22).
• Check that the Macintosh adapter and the video signal cable are properly connected (page
6).
• If you cannot find your model’s name (CPD-520GS) among the Sony monitors in the Windows 95 monitor selection screen, select the DDC standard monitor or install the Windows 95 Monitor Information Disk (page 7). The DDC standard does not apply to the 5 BNC connectors. If you use the DDC standard, connect the computer to the HD15 connector with the supplied video signal cable.
• Check your graphics board manual for the proper monitor setting.
• Check this manual and confirm that the graphics mode and the frequency you are trying to operate at is supported. Even if the frequency is within the proper range, some video boards may have a sync pulse that is too narrow for the monitor to sync correctly.

• Degauss the monitor (page 15). If you place equipment which generates a magnetic field, such as a loudspeaker, near the monitor, or you change the direction of the monitor, color may lose uniformity. The degauss function demagnetizes the metal frame of the CRT to obtain a neutral field for uniform color reproduction. If a second degauss cycle is needed, allow a minimum interval of 20 minutes for the best result.
• Adjust the landing (pages 13 – 14).
• If the control lock function is set to on, set it to off using the OPTION OSD (page 16).
• Adjust the color temperature (pages 12 – 13).
• Check that the 5 BNCs are connected in the correct order (from left to right: Red–Green– Blue–HD–VD) (page 6).
• Press the ASC button (page 7).
• Adjust the size or centering (page 10).
• Some video modes do not fill the screen to the edges. This problem tends to occur with certain video boards.
• Adjust the geometry (page 11).
• Adjust the convergence (pages 13 – 14).
• Adjust the contrast and brightness (page 9).
• Degauss the monitor (page 15). If you place equipment which generates a magnetic field, such as a loudspeaker, near the monitor, or you change the direction of the monitor, color may lose uniformity. The degauss function demagnetizes the metal frame of the CRT to obtain a neutral field for uniform color reproduction. If a second degauss cycle is needed, allow a minimum interval of 20 minutes for the best result.
• If red or blue shadows appear along the edges of images, adjust the convergence (pages 13 – 14).
• If the moire is cancelled, the picture may become fuzzy. Decrease the moire cancellation effect (pages 13 – 14).
• Isolate and eliminate any potential sources of electric or magnetic fields. Common causes for this symptom are electric fans, fluorescent lighting or laser printers.
• If you have another monitor close to this monitor, increase the distance between them to reduce the interference.
• Try plugging the monitor into a different AC outlet, preferably on a different circuit.
• Try the monitor on a different computer in a different room.
• Set the refresh rate on the computer to obtain the best possible picture by referring to the computer’s manual.
• Eliminate the use of video cable extensions and/or video switch boxes if this symptom occurs. Excessive cable length or a weak connection can produce this symptom.
• Cancel the moire (pages 13 – 14). The moire may be modified depending on the connected computer.
• Due to the relationship between resolution, monitor dot pitch and the pitch of some image patterns, certain screen backgrounds sometimes show moire. Change your desktop pattern.
• These wires stabilize the vertically striped aperture grille (page 19). This aperture grille allows more light to pass through to the screen giving the Trinitron CRT more color and brightness.
• When the power is turned on, the auto-degauss cycle is activated. While the auto-degauss cycle is activated (3 seconds), a hum may be heard. The same hum is heard when the monitor is manually degaussed. This is not a malfunction.
