SAFETY CHECK-OUT

(US Model only)

GDM-4011P

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

Voltmeter (0.75 V)

Fig. A. Using an AC voltmeter to check AC leakage.

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.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY SHADING AND MARK

ON THE SCHEMATIC DIAGRAMS, EXPLODED VIEWS AND IN THE PARTS LIST ARE CRITICAL FOR SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY. CIRCUIT ADJUSTMENTS THAT ARE CRITICAL FOR SAFE OPERATION ARE IDENTIFIED IN THIS MANUAL. FOLLOW THESE PROCEDURES WHENEVER CRITICAL COMPONENTS ARE REPLACED OR IMPROPER OPERATION IS SUSPECTED.

AVERTISSEMENT!! NE JAMAIS METTRE SOUS TENSION QUAND LA BOBINE DE DEMAGNETISATION EST ENLEVÉE.

ATTENTION AUX COMPOSANTS RELATIFS À LA

SÉCURITÉ!! LES COMPOSANTS IDENTIFIÉS PAR UNE TRAME ET UNE MARQUE

¡ SONT CRITIQUES POUR LA

SÉCURITÉ. NE LES REMPLACER QUE PAR UNE PIÈCE PORTANT LE NUMÉRO SPECIFIÉ. LES RÉGLAGES DE CIRCUIT DONT L’IMPORTANCE EST CRITIQUE POUR LA SÉCURITÉ DU FONCTIONNEMENT SONT IDENTIFIÉS DANS LE PRÉSENT MANUEL. SUIVRE CES PROCÉDURES LORS DE CHAQUE REMPLACEMENT DE COMPOSANTS CRITIQUES, OU LORSQU’UN MAUVAIS FONCTIONNE-MENT EST SUSPECTÉ.

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.

CAUTION ON DAS (ECS) CONNECTOR

• The connector for DAS (ECS) adjustment is provided inside

the cover shown below. Be careful with an electrical shock when connecting the connector with the power supplied. Also, return the removed cover to the home position.

Additional Information

Warning Messages

If there is something wrong with the input signal, one of the following messages appears. The message disappears after about 30 seconds.

Additional Information

1 The input signal condition

“OUT OF SCAN RANGE” indicates that the input signal

is not supported by the monitor’s specifications. “NO INPUT SIGNAL” indicates that no signal is input, or

the input signal from the selected input connector is not received.

2 The selected input connector

Indicates which input connector is receiving the wrong signal. If there is something wrong with the signal from both input connectors, “1” (HD15) and “2” (13W3) are displayed alternately.

To solve these problems, see “Troubleshooting” below.

Troubleshooting

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

Symptom Check these items No picture

If the u indicator is not lit

If the “NO INPUT SIGNAL” message appears on the screen, or if the u indicator is either orange or alternating green and orange

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

If no message is displayed and the u indicator is green or flashing orange

Picture is scrambled

Color is not uniform

• Check that the power cord is properly connected.

• Check that the u (power) switch is in the “on” position.

• 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.

• Ensure that no pins are bent or pushed in the HD15 or 13W3 video input connector.

• 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 20).

• 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 13). 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.

Additional Information

Symptom Check these items You cannot adjust the

monitor with the buttons on the front panel

White does not look white Screen image is not centered

or sized properly

Edges of the image are curved

White lines show red or blue shadows at edges

Picture is fuzzy

Picture bounces or has wavy oscillations

Picture is flickering

Picture appears to be ghosting

Wavy or elliptical (moire) pattern is visible

Two fine horizontal lines (wires) are visible

Hum is heard right after the power is turned on

• If the control lock function is set to on, set it to off using the OPTION OSD (page 15).

• Adjust the color temperature (page 12).

• Adjust the size or centering (pages 9 – 10).

• Some video modes do not fill the screen to the edges. This problem tends to occur with certain video boards.

• Adjust the geometry (pages 10 – 11).

• Adjust the convergence (pages 12 – 13).

• Adjust the contrast and brightness (page 8).

• If red or blue shadows appear along the edges of images, adjust the convergence (pages 12 – 13).

• If the moire is cancelled, the picture may become fuzzy. Decrease the moire cancellation effect (pages 12 – 13).

• 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 12 – 13). 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 17). 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 autodegauss cycle is activated (2 seconds), a hum may be heard. The same hum is heard when the monitor is manually degaussed. This is not a malfunction.
