CPD-520GS/520GST/520GST9 SAFETY CHECK-OUT (US Model only) 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.
CPD-520GS/520GST/520GST9 POWER SAVING FUNCTION This monitor meets the power-saving guidelines set by VESA and ENERGY 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.

See page 19 for more information on this monitor’s power saving capabilities. 1 The control lock function disables all of the buttons on the front panel except the u (power) switch, MENU and INPUT buttons. 1 Press the MENU button. The MENU OSD appears. Press the MENU button. The MENU OSD appears.
Technical Features Getting Started Technical Features Preset and User Modes This monitor has factory preset modes for the most popular industry standards for true “plug and play” compatibility. 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.
Additional Information Getting StartedInformation Additional 1 The input signal condition WarningMessages If there is something wrong with the input signal, one of the following messages appears. INFORMATION OUT OF SCAN RANGE “OUT OF SCAN RANGE” indicates that the input signal is not supported by the monitor’s specifications. Symptom Check these items Color is not uniform • Degauss the monitor (page 15).
Additional Information Self-diagnosisFunction Specifications This monitor is equipped with a self-diagnosis function. If there is a problem with your monitor or computer(s), the screen will go blank and the u indicator will either light up green or flash orange.

CPD-520GS/520GST/520GST9 SECTION 3 SAFETY RELATED ADJUSTMENT When replacing or repairing the shown below table, the following operational checks must be performed as a safety precaution against X-rays emissions from the unit. a) HV Regulator Circuit Check 1) Confirm that the voltage of the pin 2 of CN901 on D board is within the voltage range shown below. Standard: 9.00 ± 0.
SECTION 4 CPD-520GS/520GST/520GST9 ADJUSTMENTS Note: Hand degauss must be used on stand-by or power-off condition. This model has an automatic earth magnetism correction function by using an earth magnetism sensor and a LCC coil. When using a hand degauss while monitor (LCC coil) is being operated, it sometimes gets magnetized, and the system may not work properly as a result. • Landing Rough Adjustment 1. Enter the full white signal. (or the full black dots signal). 2. Adjust the contrast to the maximum.
