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. 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

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. SAFETY-RELATED COMPONENT WARNING!!

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. Set the time according to "Setting the power saving delay time" on page 1-7.
Power consumption mode 1 2 3 4 5 Normal operation Standby (1st mode) Suspend (2nd mode) Active-off (3rd mode) Power-off Screen active blank blank blank -- Horizontal sync signal present absent present absent -- Vertical sync signal present present absent absent --

Note If no video signal is input to the monitor, the "NO INPUT SIGNAL" message (page 1-9) appears. After the delay time has passed, the power saving function automatically puts the monitor into the active-off mode and the indicator lights up orange. Once the horizontal and vertical sync signals are detected, the monitor automatically resumes its normal operation mode.

SECTION 1 GENERAL

Getting Started

Getting Started Getting Started Warningonpowerconnection
· Use an appropriate power cord for 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. Examples of plug types

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.

Identifying Parts and Controls
See the pages in parentheses for further details.

Front

Rear

for 100 to 120 V AC

for 200 to 240 V AC

Maintenance
· Clean the cabinet, panel and controls with a soft cloth lightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent, such as alcohol or benzine. · Do not rub, touch, or tap the surface of the screen with sharp or abrasive items such as a ballpoint pen or screwdriver. This type of contact may result in a scratched picture tube. · Clean the screen with a soft cloth. If you use a glass cleaning liquid, do not use any type of cleaner containing an anti-static solution or similar additive as this may scratch the screen's coating.

· Before disconnecting the power cord, wait at least 30 seconds after turning off the power to allow the static electricity on the CRT display surface to discharge. · After the power has been turned on, the CRT is demagnetized (degaussed) for about 3 seconds. This generates a strong magnetic field around the metal frame, which may affect the data stored on magnetic tapes and disks near the bezel. Place magnetic recording equipment, tapes and disks away from this monitor. The outlet should be installed near the equipment and be easily accessible.

Technical Features

Getting Started Technical Features
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 size and centering. Simply press the ASC 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. A total of 15 user adjusted modes can be stored in memory. Recommended horizontal and vertical timing conditions
Horizontal sync width duty should be: >4.8% of total horizontal time. Horizontal blanking width should be: >2.8 µsec. Vertical blanking width should be: > 450 µsec.

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. Resolution Horizontal Vertical No. (dots × lines) Frequency Frequency Graphics Mode

PowerSavingFunction
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.
Power consumption mode 1 2 3 4 5 Normal operation Standby (1st mode) Suspend (2nd mode) Active-off (3rd mode) Power-off Screen active blank blank blank -- Horizontal sync signal present absent present absent -- Vertical sync signal present present absent absent --

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 16. Note
If no video signal is input to the monitor, the "NO INPUT SIGNAL" message (page 20) appears. After the delay time has passed, the power saving function automatically puts the monitor into the active-off mode and the u indicator lights up orange. Once the horizontal and vertical sync signals are detected, the monitor automatically resumes its normal operation mode. Power consumption 160 W 100 W 15 W 5W 0W Recovery time -- Approx. 3 sec.

Plug & Play
This monitor complies with the DDCTM1, DDC2B, DDC2AB and DDC2B+ Display Data Channel (DDC) standards of VESA. When a DDC1 host system is connected, the monitor synchronizes with the V. CLK in accordance with the VESA standards and outputs the EDID (Extended Display Identification Data) to the data line. When a DDC2B, DDC2AB or DDC2B+ host system is connected, the monitor automatically switches to the appropriate standard. DDCTM is a trademark of the Video Electronics Standard Association. Note
When using Windows® 95, the DDC standard does not apply to the 5 BNC connectors. If you use the DDC standard, connect the HD15 connector to the computer with the supplied video signal cable.

"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. Symptom
Color is not uniform

WarningMessages
If there is something wrong with the input signal, one of the following messages appears.
INFORMATION OUT OF SCAN RANGE INPUT : HD15

Check these items
· Degauss the monitor (page 15). 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. · Adjust the landing (pages 13 ­ 14). · If the control lock function is set to on, set it to off using the OPTION OSD (page 16).

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, "HD15" and "BNC" are displayed alternately. To solve these problems, see "Troubleshooting" below.

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. · Check that the 5 BNCs are connected in the correct order (from left to right: Red­Green­ Blue­HD­VD) (page 6). · Ensure that no pins are bent or pushed in the HD15 video input connector. · Check that the video board is completely seated in the proper bus slot. · Adjust the geometry (page 11). · Adjust the convergence (pages 13 ­ 14). · Adjust the contrast and brightness (page 9). · Degauss the monitor (page 15). 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. · If red or blue shadows appear along the edges of images, adjust the convergence (pages 13 ­ 14). · If the moire is cancelled, the picture may become fuzzy. Decrease the moire cancellation effect (pages 13 ­ 14). · 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 13 ­ 14). 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 19). 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 auto-degauss cycle is activated (3 seconds), a hum may be heard. The same hum is heard when the monitor is manually degaussed. This is not a malfunction.

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. 3. Make the screen monogreen. Note: Off the outputs from R ch and B ch of SG. 4. Reverse the DY, and adjust coarsely the purity magnet so that a green raster positions in the center of screen. 5. Adjust the tilt of DY, and fix lightly with a clamp. Note: "TILT" shall be set at 0. · Landing Fine Adjustment 1. Put the set inside the Helmholtz coil. ("LCC SW" = "12") 2. Input the single green signal and set the CONT control to MAX. Note: After the W/B adjustment with 9300K, measure an average of Ik when a full white signal is entered in the CONT MAX/BRT CENT status. Then make adjustment so that the specified screen can be attained after aging for 2 hours with Ik equivalent to 30% of the average value. 3. Demagnetize the metal part of the chassis with the hand degausser and coil degausser, and the CRT surface with the hand degausser. Input AC 230V to AC IN, turn on and off the power to perform auto degaussing. (Perform auto degaussing by setting "MON CON REG2"=152. Return to the original value after use.) Demagnetize the CRT surface with the hand degausser again. Note: (1) 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. (2) Adjust in a non-magnetic field. BV=45uT. (3) If adjusting in a magnetic fields, add the shift from the nonmagnetic field in your estimation. 4. Attach the wobbling coil to the designated part of the CRT neck. 5. Attach the sensor of the landing adjustment unit on the CRT surface.

6. Adjust the DY position and purity, and the DY tilt, and landing of the center and 4 corners with the landing checker. After adjustment, set "LCC SW" to "13". · Write terrestrial magnetism sensor reading VX and VY to "LCC VX" and LCC VY" respectively. Adjust the landing by moving "LCC NS", "LCC LT", "LCC LB", "LCC RT" and "LCC RB". However, the register adjustment must be limited within the following range. "LCC NS" 128 ± 15 "LCC LT", "LCC LB", "LCC RT", "LCC RB" 128 ± 40 Save the service data.

* Adjustment and measurement should be made at the points one inch inside the fluorescent screen. 7. For the up/down swing, swing the DY and insert a wedge so that the up and down pins are equal at the top and bottom. Adjust the DY TLV VR so that the horizontal trapezoid is equal at the left and right. Insert the wedge firmly so that the DY does not shake. 8. Check the landing of each corner, and if it does not satisfy the specification, adjust the landing of four corners using "LCC LT", "LCC LB", "LCC RT" and "LCC RB". However, the register adjustment must be limited within the following range. "LCC NS" 128 ± 15 "LCC LT", "LCC LB", "LCC RT", "LCC RB" 128 ± 40 After adjustment, save the service data. 9.
