SAFETY CHECK-OUT

SDM-N50

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

0.15 µF

1.5 k

Ω

AC Voltmete (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.

SECTION 1

The operating instructions mentioned here are partial abstracts from the Operating Instruction Manual. The page numbers of the Operating Instruction Manual remein as in the manual.

Precautions

Warning on power connections

• Use the supplied power cord. If you use a different power cord, be sure that it is compatible with 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.

For the customers in the UK

If you use the monitor in the UK, please use the appropriate UK power cord.

Installation

Do not install or leave the monitor:

• In places subject to extreme temperatures, for example near a radiator, heating vent, or in direct sunlight. Subjecting the monitor to extreme temperatures, such as in an automobile parked in direct sunlight or near a heating vent, could cause deformations of the casing or malfunctions.

• In places subject to mechanical vibration or shock.

• Near any equipment that generates a strong magnetic field, such as a TV or various other household appliances.

• In places subject to inordinate amounts of dust, dirt, or sand, for example near an open window or an outdoor exit. If setting up temporarily in an outdoor environment, be sure to take adequate precautions against airborne dust and dirt. Otherwise irreparable malfunctions could occur.

This monitor has a built-in stereo speaker in base of the display stand. We recommend that you position the LCD panel slightly away from the display stand. High tones from the speaker may be muffled if the LCD panel is positioned immediately on top of the stand. Be careful not to drop any metal object into the speaker's vents as the speakers generate a magnetic field. Also, this magnetic field may affect data stored on magnetic tapes and discs. Be sure to keep magnetic recording equipment, tapes, and floppy discs away from the speaker’s opening. A duct is provided on the rear part of the display stand to boost the bass. Be sure not to block the duct with paper or other objects to ensure clear sound.

Technical Features

Power saving function (user sensor/power saving mode)

This monitor meets the power-saving guidelines set by VESA,

ENERGY STAR, and NUTEK. If the monitor is connected to a computer

or video graphics board that is DPMS (Display Power Management Signaling) compliant, the monitor will automatically enter the power saving mode. It automatically enters the low power consumption mode when the user sensor detects the absence of a user.

1 Low power consumption mode (user sensor)

When the user sensor in the monitor detects the absence of a user, the monitor enters low power consumption mode after about 20 seconds. In low power consumption mode, the monitor is in a power saving state and shuts off power to all circuitry (except for that of the sensors) regardless of the setting of the computer. The monitor returns to normal operation mode when the presence of a user is detected by the user sensor. When the monitor enters the power saving mode (as set according to the computer’s settings), the power saving mode takes precedence over the low power consumption mode. In this case, the monitor stays in the power saving mode regardless of the presence or absence of a user. To return the monitor to normal operation mode, reset the computer’s power saving mode.

Note

The user sensor detects the presence/absence of a user up to a distance of approximately 60 cm from the screen surface. However, this distance may vary depending on the user’s clothes or the brightness of the surrounding area. If user detection fails due to the ambient conditions of the surrounding area, set the user sensor to OFF. If your monitor does not automatically return from low power consumption mode due to the failure of the user sensor to detect the presence of a user, press the 1 (power) switch twice to turn the monitor off and then on.

2 Power saving mode

DPMS defines three power saving states according to the state of the sync signals supplied from the computer. This monitor’s power consumption is input at approximately 3 W in all of these states if the power saving function is set to ON. When your computer enters in the power saving mode, the input signal is cut and NO INPUT SIGNAL appears on the screen. After a few seconds, the monitor enters power saving mode.

* “Sleep” and “deep sleep” are power saving modes defined by the

Environmental Protection Agency.

Note

The power saving function may not work normally if sync signals other than those listed above are supplied. In such a case, set the power saving function to OFF.

Automatic brightness adjustment function (light sensor)

This monitor is provided with a feature to automatically adjust the screen brightness according to the brightness of the surroundings. The brightness of the backlight is set to the most appropriate level by setting the light sensor to ON. The default setting of the brightness of the backlight is set to its maximum. When the light sensor setting is set to ON, the monitor adjusts the brightness of the backlight linearly from its lower- to upper-limit values. When the user adjusts the backlight, the backlight brightness is automatically adjusted between the user adjustment value and the upper- and lower-limit values.

Automatic picture quality adjustment function

When the monitor receives an input signal, it automatically matches the signal to one of the factory preset modes stored in the monitor’s memory to provide a high quality picture at the center of the screen. (See Appendix for a list of the factory preset modes.) For input signals that do not match one of the factory preset modes, the automatic picture quality adjustment function of this monitor automatically adjusts the picture position, phase, and pitch, and ensures that a clear picture appears on the screen for any timing within the monitor’s frequency range (horizontal: 30 – 61 kHz, vertical: 50 – 85 Hz). Consequently, the first time the monitor receives input signals that do not match one of the factory preset modes, the monitor may take a longer time than normal for displaying the picture on the screen. This adjustment data is automatically stored in memory so that next time, the monitor will function in the same way as when the monitor receives the signals that match one of the factory preset modes. In all modes as above, if the picture is adjusted, the adjustment data is stored as a user mode and automatically recalled whenever the same input signal is received.

Note on the adjusting the phase

If the automatic picture quality adjustment function is activated, the picture moves slightly whenever the monitor receives the input signal, regardless of the stored adjustment.

Note

While the automatic picture quality adjustment function is activated, only the 1 (power) switch, and INPUT button will operate.
