SAFETY CHECK-OUT

(US Model only)

CPD-200ES

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

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 microampere). 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 instructions.

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 low voltage scale. The Simpson's 250 and Sanwa SH-63Trd are examples of passive VOMs that are suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A)

Entering New Timings

When using a video mode that is not one of the factory preset modes, some fine tuning may be required to optimize the display to your preferences. Simply adjust the monitor according to the preceding adjustment instructions. The adjustments will be stored automatically and recalled whenever that mode is used. A total of 8 user-defined modes can be stored in memory. If the 9th mode is entered, it will replace the first.

Power Saving Function

This monitor meets the power saving guidelines set by the International

NERGY STAR Program as well as the more stringent TCO92 803299 (NUTEK) guidelines. It is capable of reduced power consumption when used with a computer equipped with Display Power Management Signaling (DPMS). By sensing the absence of the sync signal coming from the computer, it will reduce the power consumption as follows:

CAUTION: The Power Saving function will automatically

put the monitor into Active-off state if the power switch is turned on without any video signal input. Once the horizontal and vertical syncs are sensed, the monitor will automatically return to its Normal operation state.

Plug and Play

This monitor complies with DDC

1 and DDC2B, which are the 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 host system is connected, the monitor automatically switches to the DDC2B communication.

Troubleshooting

This section may help you isolate a problem and as a result, eliminate the need to contact technical support, allowing continued productivity.

No picture

/ If the u POWER indicator is not lit.

— Check that the power cord is properly

connected.

— Check that the u POWER switch is in the

“ON” position.

/ If the u POWER indicator is flashing in green

and orange alternately.

— Check that your computer power switch is in

the “ON” position.

— The monitor will recover when you press any

key on the keyboard of the computer.

— Check that the video cable is properly

connected.

— Ensure that no pins are bent or pushed in the

HD15 connector of the cable.

— Check that the video card is seated

completely in a proper bus slot.

— Check that the video sync signal is within

that specified for the monitor.

— If using a Macintosh system, check that a

proper HD15 - D15 adapter is provided to work correctly with your Macintosh.

— The monitor has a self-diagnose function.

After disconnecting the video signal cable from the computer, turn on the u POWER switch of the monitor. Press and hold the "+" side of the

button for 2 seconds, then color bars will appear. The monitor is operating normally if the red, green, and blue color bars appear. Contact the maker of the computer to which the monitor is connected.

/ If the u POWER indicator is flashing.

— There is a potential monitor failure. Contact

your dealer.

If the message of “OUT OF SCAN RANGE” appears on the screen

/ Check that the video sync signal is specified for

the monitor.

Picture is scrambled

/ Check your graphics board manual for the

proper monitor setting on your Multiscan 100ES/ 200ES.

/ Check this manual and confirm that the graphic

mode and the frequency at which you are trying to operate is supported. Even within the proper range some video boards may have a sync pulse that is too narrow for the monitor to sync correctly.

Color is not uniform

/ If the monitor is close to any potential sources of

magnetic fields such as a speaker, or you turn the monitor while the u POWER switch is in the “ON” position, color may not be uniform. Trip the u POWER switch once to activate the Autodegauss cycle*.

Picture is flickering

/ If the refresh rate is not appropriate, the picture

may flicker. Set the refresh rate of the non-interlace mode as high as possible on the computer. For detailes on how to set the refresh rate, consult the dealer of your

computer or

video board.

Screen image is not centered or sized properly

/ Adjust the “CENTER,” “SIZE,” or “GEOMETRY”

on the OSD (pages 5, 6).

/ Some video modes do not fill the screen to the

edge of the monitor. There is no single answer to solve the problem. There is a tendency to have this problem on higher refresh timings and Macintosh video timings.

Picture is fuzzy

/ Adjust the “CONTRAST” and “BRIGHTNESS”

on the OSD (page 5). We have come across several brands of SVGA boards that have an excessive video output level which creates a fuzzy picture at max contrast.

/ Trip the u POWER switch once to activate the

Auto-degauss cycle∗.

Picture bounces or has wavy oscillations

/ Isolate and eliminate any potential sources of

electric or magnetic fields. Common causes for this symptom are electric fans, fluorescent lighting, laser printers, and so on.

/ 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 completely different

computer in a different room.

Picture appears to be ghosting

/ Eliminate the use of video cable extension cables

and/or video switch boxes if this symptom occurs. Excessive cable length or weak connections can produce this symptom.

A fine horizontal line (wire) is visible

/ This wire stabilizes the vertically striped

Aperture Grille (page 8). This Aperture Grille allows more light to pass through to the screen giving the Trinitron CRT more color and brightness.

Wavy or elliptical (moire) pattern is visible

/ Due to the relationship between resolution,

monitor AG pitch and the pitch of some image patterns, certain screen backgrounds, especially gray, sometimes show moire. This can only be eliminated by changing your desktop pattern.

Just after turning the monitor on, a “boon” noise is heard

/ Just after turning the monitor on, a noise may be

heard for about 3 seconds. This noise is not failure, it is caused by the Autodegauss cycle∗.

∗The Auto-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 the problem persists, call your authorized Sony dealer from

a location near your monitor.

•Note the model name and the serial number of your monitor.

Also note the make and name of your computer and video board.
