Power Saving Function

This monitor meets the power-saving guidelines set by

VESA and

NERGY STAR, as well as the more stringent NUTEK . If the monitor is connected to a computer or video graphics board that is VESA DPMS (Display Power Management Signaling) compliant, the monitor will automatically reduce power consumption in three stages as shown 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 1-6.

* Power consumption of the monitor only. The figures in

parentheses are power consumption of the monitor including the AC adapter.

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

the Environmental Protection Agency.

*** When your computer enters the power saving mode, the input

signal is cut and NO INPUT SIGNAL appears on the screen. After the time set in “Changing the Power Saving Delay Time” (page 1-6) has elapsed, the monitor enters the power saving mode.

SAFETY CHECK-OUT

CPD-L181A

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.

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.

Getting Started

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.

Handling the LCD screen

• Bright points of light (red, blue or green) may appear on the LCD screen. This is not a malfunction. The LCD screen is made with high-precision technology and more than 99.99 % of the picture element is intact. However, some of the picture element may not appear or some of the picture element may appear constantly.

• Do not leave the LCD screen facing the sun as it can damage the LCD screen. Take care when you place the monitor by a window.

• Do not push or scratch the LCD screen. Do not place a heavy object on the LCD screen. This may cause the screen to lose uniformity.

• If the monitor is used in a cold place, a residual image may appear on the screen. This is not a malfunction. When the monitor becomes warm, the screen returns to normal.

• If a still picture is displayed for a long time, a residual image may appear. The residual image will eventually disappear.

• The screen and the cabinet become warm during operation. This is not a malfunction.

About the fluorescent tube

A specially designed fluorescent tube is installed as the lighting apparatus for this monitor. If the LCD screen becomes dark, unstable or does not turn on, consult your Sony dealer.

Preset and User Modes

This monitor has factory preset modes for the most popular industry standards for true “plug and play” compatibility. (See Appendix for a list of the factory preset modes.) When a new input signal is entered, the monitor selects the appropriate factory preset mode and momentarily adjusts the phase calibration to provide a high quality picture to the center of the screen. The calibration is stored in memory and is immediately recalled whenever the same input signal is received. For input signals that do not match one of the factory preset modes, the digital Multiscan technology of this monitor performs all of the adjustments necessary to ensure that a clear picture appears on the screen for any timing in the monitor’s frequency range. However, it may be necessary to fine tune the vertical/horizontal centering. Simply press the AUTO button or adjust the monitor according to the adjustment instructions. The adjustments are stored automatically as a user mode and recalled whenever the corresponding input signal is received.

Power Saving Function

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

* Power consumption of the monitor only. The figures in

parentheses are power consumption of the monitor including the AC adapter.

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

the Environmental Protection Agency.

*** When your computer enters the power saving mode, the input

signal is cut and NO INPUT SIGNAL appears on the screen. After the time set in “Changing the Power Saving Delay Time” (page 15) has elapsed, the monitor enters the power saving mode.

Troubleshooting

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

On-screen messages

If there is something wrong with the input signal, one of the following messages appears on the screen. To solve the problem, see “Trouble symptoms and remedies” on page 18.

“OUT OF SCAN RANGE” indicates that the input signal is not supported by the monitor’s specifications.
