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 poorly­soldered 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.
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 microampere). 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 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's 250 and Sanwa SH-63Trd are examples of passive VOMs that are suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A)
HOW TO FIND A GOOD EARTH GROUND
A cold-water pipe is guaranteed earth ground; the cover-plate retaining screw on most AC outlet boxes is also at earth gr ound. 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 r eading should be zero ohms. If a cold-water pipe is not accessible, connect a 60-l00 watts 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 of the line, the lamp should light at normal brilliance if the screw is at ground potential. (See Fig. B)

Using This Manual
Precautions
Welcome!
Thank you for purchasing the Sony Trinitron
®
Color TV. This manual is written for the models listed below. Before reading, check the model number located on the front of this manual or on the rear of your TV.
Model KV-35S45 is used for menu and illustration purposes. Differences in operation are indicated in the text; for example, “KV-35S45 only”.
This manual is divided into four major sections. We recommend that you carefully review the contents of each section in the order presented to ensure that you fully understand the operation of your new TV.
1 Connecting and Installing the TV
This section guides you through your initial set up. It shows how to connect to your antenna or cable, and connect any accessories or components.
2 Basic Set Up
This section teaches you the basic skills needed to operate your new TV. It shows you how to operate special functions of the remote control.
3 Using your New TV
This section shows you how to begin using your new TV. It shows how to use the Easy Set Up Guide feature, and how to use your remote control.
4 Using your Menus
This section teaches you how to access on-screen menus and adjust your TV's settings.
Instructions in this manual are written for the remote control. Similar controls may be found on the TV console.
Safety
• Operate the TV only with 120 V AC .
• The plug is designed, for safety purposes, to fit in the wall outlet only one way. If you are unable to insert the plug fully into the outlet, contact your dealer.
• If any liquid or solid object should fall inside the cabinet, unplug the TV immediately and have it checked by qualified personnel before operating it further.
• If you will not be using the TV for several days, disconnect power by pulling the plug itself. Never pull on the cord.
For details concerning safety precautions, see the supplied leaflet “IMPORTANT SAFEGUARDS”.
Installing
• To prevent internal heat build-up, do not block the ventilation openings.
• Do not install the TV in a hot or humid place, or in a place subject to excessive dust or mechanical vibration.

Connecting a camcorder
This connection is convenient for viewing a picture directly from your camcorder.
Using A/V connectors, connect AUDIO and VIDEO OUT on your camcorder to AUDIO and VIDEO IN on your TV.
Connection can also be made directly to your A/V input located on the rear of your TV.
Note
If you are connecting a monaural camcorder, connect only the single white audio output to the left input on your TV.
If you have an S VIDEO equipped camcorder, you can use an S Video cable for optimum picture quality.

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

Preparation:
Input a white pattern signal.
Face the picture tube in a East or West direction to reduce the influence of geomagnetism.
NOTE: Do not use the hand degausser because it magnetizes the CRT .
1. Input white pattern from pattern generator.
2. Loosen the deflection yoke mounting screw, and set the purity control to the center as shown below:
5. Move the deflection yoke forward, and adjust so that the entire screen becomes green.
3. Input green pattern from pattern generator.
4. Move the deflection yoke backward, and adjust with the purity control so that green is in the center and red and blue are even on both sides.

SAFETY RELATED ADJUSTMENTS
R530, R531 CONFIRMATION METHOD (HOLD-DOWN CONFIRMATION) AND READJUSTMENTS
Always perform the following adjustments when replacing the following components marked with a ] mark on the schematic diagram:
A BOARD: IC351, IC501, D519, D520, D521, C531,
C532, R387, R529, R530, R531, R532, R533, R550, T503
G BOARD: IC643, R661
Step 1 Preparation before Confirmation
Turn the POWER switch ON.
Input a white signal and set the PICTURE and BRIGHT controls to maximum.
Confirm that the voltage at the check terminal of TP85 is more than 18.0 V DC when the set is operating normally.
At AC input: 120.0 ± 2.0 VAC
or220.0 ± 2.0 VAC (for 34SL40C/34VL65C/37VL65C only)

Step 5
Confirm that a voltage of more than 18.0 V DC appears between TP85 and ground.
At AC input: 120.0 ± 2.0 VAC
or 220.0 ± 2.0 VAC (for 34SL40C/34VL65C/37VL65C only)
B+ VOL TAGE CONFIRMATION AND ADJUSTMENT
Always perform the following adjustments when replacing the following components marked with ] on the schematic diagram:
G BOARD: IC643, R661
1) Using Variac, apply AC input voltage: 130
(or 220.0 ± 2.0 VAC
for 34SL40C/34VL65C/37VL65C only)
2) Input a monoscope signal.
3) Set the PICTURE control and the BRIGHT control to initial reset value.
+ 2.0 VAC
Increase the voltage gradually and confirm that the holdown works (raster disappears) at lower than the voltage recorded in Step 3.
Lower than 22.05 V DC
At AC input: 120.0 ± 2.0 VAC
or 220.0 ± 2.0 VAC (for 34SL40C/34VL65C/37VL65C only)
— 15 —
4) Confirm the voltage of G BOARD CN641 between pin 1 to ground is less than 135.5
+ 1.0 V DC.
5) If step 4 is not satisfied, replace the R661and repeat the above steps.
