SAFETY CHECK-OUT

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 connector shell, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC Leakage. Check leakage as described right.

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 microamperes). Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA WT540A. 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 low-voltage 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)

POWER SAVING FUNCTION

AUTOMATIC PICTURE QUALITY ADJUSTMENT FUNCTION

(ANALOG RGB)

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

E

NERGYSTAR, 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 reduce power consumption as shown below.

Power mode Power consumption (power)

indicator

normal

58 W (max.) green

operation active off*

3 W (max.) orange

(deep sleep)**

(power) off 1 W red

main power off 0 W off

* When your computer enters the “active off” mode, the input signal is

cut andNOINPUT SIGNALappearsonthe screen. After 10 seconds, the monitor enters the power saving mode.

** “Deep sleep” is a power saving mode defined by the Environmental

Protection Agency.

Note

ZZ...

If the (POWER SAVE) is set to OFF(page 16), the monitor does not enter the power saving mode.

When the monitor receives an input signal, it automatically adjusts the picture’s position and sharpness(phase/pitch),and ensuresthata clear picture appears on the screen.

The factory preset mode

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. If the input signal matches the factory preset mode, the picture is appears on the screen automatically with the appropriate default adjustment.

If input signals do not match one of the factory preset modes

When the monitor receives an input signal, the automatic picture quality adjustment function of this monitor is activated and ensures that a clear picture always appears on the screen (within the following monitor frequency ranges): Horizontal frequency:28 – 92 kHz Vertical frequency: 56 – 85Hz 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.

If you adjust the phase, pitch, and pictures position manually

For some input signals, the automatic picture quality adjustment function of this monitor may not completely adjust the picture position,phase,and pitch. Inthiscase, you can manuallyset these adjustments (page 12). If you manually set these adjustments, they are stored in memory as user modes and automatically recalled whenever the monitor receives the same input signals.

SDM-P82(UC) 4

Press the POWER button with pressing the UP (↑) and OK buttons in the power-off state, and the data for the model information are copied to the EEPROM for the internal microcontroller from EDID of INPUT2: HD15, and the model information display is made correct. When replacing the A board, this operation is required after writing EDID and at the same time ETI is reset to 0.

7. To enter the ISP mode

Turn on the MAIN POWER switch with pressing the DOWN (↓) button in the main-power-off state, and the system enters the ISP mode. The POWER LED goes off, and both input LED's 1 and 2 light on, and the picture disappears, and any button becomes invalid. In the ISP mode, the internal software can be updated with an external personal computer using a special fixture. To cancel the ISP mode, turn off the MAIN POWER switch.

4. To set the NO SYNC AGING flag

Press the POWER button with pressing the UP (↑) button in the power-off state, and the NO SYNC AGING flag is set. In this setting, when the input with no input signal is selected, the system goes into the AGING MODE. The NO SYNC AGING flag is held until it is cleared. To clear the NO SYNC AGING flag, go into the service mode and then set the AGING MODE to OFF, or execute the all mode recall.

2-3. Functions of Service Mode

2-4. White Balance Adjustment

1. COLOR TEMP

This is used for the white balance adjustment at color temperature 9300 K and 6500 K. The adjustment requires to be done for every input (INPUT1: DVI-D, INPUT1: HD15, or INPUT2: HD15) by switching the input. The adjustment data is stored into the register for respective inputs.

2. INITIAL EEPROM

This sets the data of the EEPROM to the default data. This operation is not required usually.

3. CLEAR ETI TIME

This resets the ETI (Elapsed Time Indicator) counter to 00000 H.

4. EEPROM TEST

This tests writing and reading of the EEPROM.

5. RGB RESET

This adjust the offset and gain of the input AD converter for the analog inputs (INPUT1: HD15 and INPUT2:HD15). As these adjustments are common to both inputs, perform them for either input. It is unnecessary for another input. Execute the adjustments under the condition where the signal specified in "White Balance Adjustment" is input.

6. AGING IN MODE

This sets and clears the NO SYNC AGING flag. AGING MODE = ON: Sets the NO SYNC AGING flag. AGING MODE = OFF: Clears the NO SYNC AGING flag. When the NO SYNC AGING flag is set and the input with no input signal is selected, the system goes into the AGING MODE. The NO SYNC AGING flag is held until it is cleared. To clear the NO SYNC AGING flag, go into the service mode and then set the AGINGN MODE to OFF, or execute the all mode recall.

1. Preparation

(1) Measurement point : Center of screen (2) Measurement distance : 50 cm (3) Measurement angle : 90° (4) Color analyzer (Minolta CS-1000 or equivalent) (5) Signal generator (Astro Design VG-828D or equivalent) Be sure to calibrate the analog RGB output level with 75Ω termination.

2. Service mode setting

Enter the service mode referring to step 1 and 2 of Section 2-2.

3. Aging

Set the AGING MODE in the service mode to ON. Disconnect the signal input terminal or select the input with no signal input, and the system goes into the AGING MODE. Execute aging for 30 minutes or more.

4. User control setting

Feed a signal to the selected input, and then execute reset in the menu screen. Then, move the menu display position to avoid the measurement point. Or, set the following for respective inputs.

BACKLIGHT (Brightness of backlight) = 100 CONTRAST = 70 BRIGHTNESS = 50 Menu display position = not center of screen (Avoid the measurement point.) (The setting of the menu display position is common to respective inputs.) ECO = OFF (The setting of ECO is common to respective inputs.)

Do not change the above setting until the white balance adjustment is completed.

7. CONTROL REG.

This can check the data of the internal registers. This operation is not required usually.
