POWER MANAGEMENT
The power saving mode complies with the VESA Display Power Management Signaling standard. Each state of power management shall be activated by the host computer terminating the appropriate sync signals. Blanking the video must precede termination of the sync signals. The elapsed time counter shall also be controlled by the host computer. Reactivation of the monitor shall be accomplished from the host computer by re-establishing the normal sync signal.
Power consumption Screen Horizontal Vertical Power Recovery time Indicator mode (video) sync signal sync signal consumption
1 Normal operation 135W -- Green
2 Active-off* (deep sleep)** 3 W . Orange
3 Power-off -- -- -- Approx. 0 W -- Off
* When your computer enters power saving mode, the input signal is cut and NO SIGNAL appears on the screen before the monitor enters active off mode. After a minute, the monitor enters power saving mode. ** "Deep sleep" is power saving mode defined by the Environmental Protection Agency.

WARNINGS AND CAUTIONS
CAUTION
Short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield, or carbon painted on the CRT, after removing the anode.
WARNING!!
An isolation transformer should be used during any service to avoid possible shock hazard, because of live chassis. The chassis of this receiver is directly connected to the ac power line.
! SAFETY-RELATED COMPONENT WARNING!!
Components identified by shading and ! mark on the schematic diagrams, exploded views, and in the parts list are critical for safe operation. Replace these components with Sony parts whose part numbers appear as shown in this manual or in supplements published by Sony. Circuit adjustments that are critical for safe operation are identified in this manual. Follow these procedures whenever critical components are replaced or improper operation is suspected.
ATTENTION!!
Apres avoir deconnecte le cap de l’anode, court-circuiter l’anode du tube cathodique et celui de l’anode du cap au chassis metallique de l’appareil, ou la couche de carbone peinte sur le tube cathodique ou au blindage du tube cathodique.
Afin d’eviter tout risque d’electrocution provenant d’un chássis sous tension, un transformateur d’isolement doit etre utilisé lors de tout dépannage. Le chássis de ce récepteur est directement raccordé à l’alimentation du secteur.

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 touching 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.
Leakage TestThe 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 WT-540A. Follow the manufacturers’ instructions to use these instructions.
2. A battery-operated AC milliampmeter. 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’s 250 and Sanwa SH-63TRD are examples of passive VOMs that are suitable. Nearly all battery-operated digital multimeters that have a 2 VAC range are suitable (see Figure A).
How to Find a Good Earth GroundA cold-water pipe is a guaranteed earth ground; the cover-plate retaining screw on most AC outlet boxes is also at earth ground. If the retaining screw is to be used as your earth ground, verify that it is at ground by measuring the resistance between it and a cold-water pipe with an ohmmeter. The reading should be zero ohms.
If a cold-water pipe is not accessible, connect a 60- to 100-watt trouble- light (not a neon lamp) between the hot side of the receptacle and the retaining screw. Try both slots, if necessary, to locate the hot side on the line; the lamp should light at normal brilliance if the screw is at ground potential (see Figure B).

ANODE CAP REMOVAL
WARNING: High voltage remains in the CRT even after the power is disconnected. To avoid electric shock, discharge CRT before attempting to remove the anode cap. Short between anode and coated earth ground strap of CRT.NOTE: After removing the anode cap, short circuit the anode of the picture tube and the anode cap to either the metal chassis, CRT shield, or carbon painted on the CRT.
REMOVAL PROCEDURES
HOW TO HANDLE AN ANODE CAP1. Do not use sharp objects which may cause damage to the surface of the anode
cap. 2. To avoid damaging the anode cap, do not squeeze the rubber covering too hard.
A material fitting called a shatter-hook terminal is built into the rubber. 3. Do not force turn the foot of the rubber cover. This may cause the shatter-hook
terminal to protrude and damage the rubber.
Turn up one side of the rubber cap in the direction indicated by arrow a .
Use your thumb to pull the rubbercap firmly in the direction indicatedby arrow b .
When one side of the rubber cap separates from the anode button, the anode cap can be removed by turning the rubber cap and pulling it in the direction of arrow c .

InstallationDo not install the monitor in the following places:• on surfaces (rugs, blankets, etc.) or near materials (curtains,
draperies, etc.) that may block the ventilation holes• near heat sources such as radiators or air ducts, or in a place
subject to direct sunlight• in a place subject to severe temperature changes• in a place subject to mechanical vibration or shock• on an unstable surface• near equipment which generates magnetism, such as a
transformer or high voltage power lines• near or on a magnetically charged metal surface.• in a small space around the top, bottom and sides of the monitor
that may block the ventilation holes.
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.
TransportationWhen you transport this monitor for repair or shipment, use the original carton and packing materials.
Use of the Tilt-SwivelThis monitor can be adjusted within the angles shown below. To find the center of the monitor’s turning radius, align the center of the monitor’s screen with the centering mark on the stand.Hold the monitor at the bottom with both hands when you turn it horizontally or vertically. Be careful not to pinch your fingers at the back of the monitor when you tilt the monitor up vertically.
NoteDo not remove the tilt-swivel base from the monitor.
Warning on power connection• Use an appropriate power cord for your local power supply.
• 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 a few 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 equipment should be installed near an easily accessible electrical outlet.

SetupThis monitor works with platforms running at horizontal frequencies between 30 and 130 kHz.
Step 1:Connect your monitor to your computer
Turn off the monitor and computer before connecting.Connect the appropriate end of the video signal cable to the video output of your computer.Connect the other end of the video signal cable to the appropriate input of the monitor.If you attach the video signal cable to the video input connector 1 on the back of the monitor, set the (input) switch on the front of the monitor to 1.
Notes• Do not touch the pins of the video signal cable connector as this might
bend the pins.• When connecting the video signal cable, check the alignment of the
video input connector. Do not force the video input connector in the wrong way or the pins might bend.
Step 2:Connect the power cordWith the monitor and computer turned off, first connect the proper power cord for your local supply to the monitor, then connect it to a properly grounded power outlet.
Step 3:Turn on the monitor and computer
First turn on the monitor, then turn on the computer.
The installation of your monitor is complete.If necessary, use the monitor’s controls to adjust the picture.
If no picture appears on your screen• Check that the monitor is correctly connected to the computer.• If NO SIGNAL appears on the screen, try changing the input
signal (page 6), and confirm that your computer’s graphics board is completely seated in the correct bus slot.
• If you are replacing an old monitor with this model and OUT OF SCAN RANGE appears on the screen, reconnect the old monitor. Then adjust the computer’s graphics board so that the horizontal frequency is between 30 – 130 kHz and the vertical frequency is between 48 – 170 Hz.
For more information about the on-screen messages, see “Trouble symptoms and remedies” on page 17.
Workplace Preparation
Positioning the MonitorChoose a suitable place to position the monitor where it is not near fluorescent desk lighting or any equipment that produces magnetic fields that could cause interference.Ensure that the furniture or equipment can support the weight of the monitor. Allow at least 2 inches (50mm) ventilation space around the monitor.
HeightThe monitor should be positioned so that the top of the screen is slightly below your eye level when you sit at your workstation.
OrientationChoose a position that gives the least reflection from lights and windows, usually at a right angle to any windows. The monitor should be positioned directly in front of you so that you do not have to twist your body. Tilt the monitor to a comfortable viewing angle.
Working Practices
RestTake regular breaks. Vary your posture, and stand up and stretch occasionally as prolonged use of computer workstations can be tiring.
BackYou should sit back in the chair and use the backrest.
HandsUse a light touch on the keyboard, keeping your hands and fingers relaxed. Allow a space in front of the keyboard to rest your wrists when not typing. Consider using a wristpad.
EyesightWorking with monitors, in common with any kind of prolonged close work, can be visually demanding. Look away from the screen periodically and have your eyesight checked regularly.
Screen settingsSet the screen brightness and contrast to a comfortable level.You may have to adjust this as the lighting changes during the day. Many application programs let you select color combinations which can help you to view in comfort.

Technical Features
Preset and user modesWhen 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 page 20 for a list of the factory preset modes.) For input signals that do not match one of the factory preset modes, the digital Multiscan technology of this monitor ensures that a clear picture appears on the screen for any timing in the monitor’s frequency range (horizontal: 30 – 130 kHz, vertical: 48 – 170 Hz). 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 for Windows usersFor Windows users, check your graphics board manual or the utility program which comes with your graphics board and select the highest available refresh rate to maximize monitor performance.
Power saving functionThis monitor meets the power-saving guidelines set by VESA and ENERGY STAR. If no signal is input to the monitor from your computer, the monitor will automatically reduce power consumption as shown below.
* When your computer enters power saving mode, the input signal is cut and NO SIGNAL appears on the screen before the monitor enters active off mode. After a minute, the monitor enters power saving mode.
**“Deep sleep” is power saving mode defined by the Environmental Protection Agency.
TroubleshootingBefore contacting technical support, refer to this section.
If thin lines appear on your screen (damper wires)The visible lines on your screen especially when the background screen color is light (usually white), are normal for the Trinitron monitor. This is not a malfunction. These are shadows from the damper wires used to stabilize the aperture grille. The aperture grille is the essential element that makes a Trinitron picture tube unique by allowing more light to reach the screen, resulting in a brighter, more detailed picture.
On-screen messagesIf there is something wrong with the input signal, one of the following messages appears on the screen.
If NO SIGNAL appears on section 1This indicates that no signal is input from the selected video input connector.Power mode Power consumption ! (power)

PRINTING THE SERVICE MANUAL
The PDF of this service manual is not designed to be printed from cover to cover. The pages vary in size, and must therefore be printed in sections based on page dimensions.
NON-SCHEMATIC PAGESData that does NOT INCLUDE schematic diagrams are formatted to 8.5 x 11 inches and can be printed on standard letter-size and/or A4-sized paper.
SCHEMATIC DIAGRAMSThe schematic diagram pages are provided in two ways, full size and tiled. The full-sized schematic diagrams are formatted on paper sizes between 8.5” x 11” and 18” x 30” depending upon each individual diagram size. Those diagrams that are LARGER than 11” x 17” in full-size mode have been tiled for your convience and can be printed on standard 11” x 17” (tabloid-size) paper, and reassembled.
TO PRINT FULL SIZE SCHEMATIC DIAGRAMS
If you have access to a large paper plotter or printer capable of outputting the full-sized diagrams, output as follows:
1) Note the page size(s) of the schematics you want to output as indicated in the middle window at the bottom of the viewing screen.
2) Go to the File menu and select Print Set-up. Choose the printer name and driver for your large format printer. Con fi rm that the printer settings are set to output the indicated page size or larger.
3) Close the Print Set Up screen and return to the File menu. Select “Print...” Input the page number of the schematic(s) you want to print in the print range window. Choose OK.
TO PRINT TILED VERSION OF SCHEMATICS
Schematic pages that are larger than 11” x 17” full-size are provided in a 11” x 17” printable tiled format near the end of the document. These can be printed to tabloid-sized paper and assembled to full-size for easy viewing.
If you have access to a printer capable of outputting the tabloid size (11” x 17”) paper, then output the tiled version of the diagram as follows:
1) Note the page number(s) of the schematics you want to output as indicated in the middle window at the bottom of the viewing screen.
2) Go to the File menu and select Print Set-up. Choose the printer name and driver for your printer. Con fi rm that the plotter settings are set to output 11” x 17”, or tabloid size paper in landscape ( ) mode.
3) Close the Print Set Up screen and return to the File menu. Select “Print...” Input the page number of the schematic(s) you want to print in the print range window. Choose OK.
TO PRINT SPECIFIC SECTIONS OF A SCHEMATIC
To print just a particular section of a PDF, rather than a full page, access the Graphics Select tool in the Acrobat Reader tool bar.
1) To view the Graphics Select Tool, press and HOLD the mouse button over the Text Select Tool which looks like: This tool will expand to reveal to additional tools. Choose the Graphics Select tool by placing the cursor over the button on of the far right that looks like:
2) After selecting the Graphics Select Tool, place your cursor in the document window and the cursor will change to a plus (+) symbol. Click and drag the cursor over the area you want to print. When you release the mouse button, a marquee (or dotted lined box) will be displayed outlining the area you selected.
3) With the marquee in place, go to the fi le menu and select the “Print...” option. When the print window appears, choose the option under the section called “Print Range” which says “Selected Graphic”.
Select OK and the output will print only the area that you outlined with the marquee.

ON-SCREEN SEARCH OPTION
All of the text within the service manual PDF is content searchable. This means that you can enter any text, word, phrase or reference number that appears in the manual, and the PDF software will search, fi nd and move the cursor to the location where you requested text fi rst appears. This feature can be particularly useful in locating components on a specifi c schematic or printed wire circuit board (PWB) diagrams.
Follow these steps to effectively locate a component on a schematic diagram:
1) Locate the schematic you want to search by clicking on the corresponding bookmark on the left side of the screen. The view on the right of the screen will then jump to the desired schematic page.
2) Magnify the diagram to at least 400% before conducting a component search. This will enable you to easily view the reference number when it is highlighted on screen. To do this, click on the magnifying glass button on the tool bar at the top of the screen. Move the cursor over the diagram and RIGHT click you mouse. Select the 400% magnifi cation option on the pop-up menu. Click on the button with the icon of the open hand to deactivate the magnifi cation tool
3) Search the diagram (or the entire manual) by clicking on the binocular button tool at the top of the screen. The “Find” window will appear and allow you to type in your desired text. Type in a reference designator, such as R502, and click on the “Find” button. If the component is not on the diagram, but is listed anywhere else in the manual, the cursor will jump to the fi rst location the text is found in the fi le. To fi nd another instance of that same text, click on the binocular button again and select “Find Again.”
