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 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-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)

SECTION 1
GENERAL
The instructions mentioned here are partial abstracts from the Operating Instruction Manual. The page numbers shown reflect those of the Operating Instruction Manual.
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".

Precautions
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".
Using This Manual
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.

ANODE-CAP REMOVAL
WARNING: NOTE: 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. After removing the anode, 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
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 surface of the anode-cap. Do not squeeze the rubber covering too hard to avoid damaging 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 separates from the anode button, the anodecap can be removed by turning the rubber cap and pulling it in the direction of arrow .

At AC input: 120.0 ± 2.0 VAC or 220.0 ± 2.0 VAC (for 34SL40C/34VL65C/37VL65C only) 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)

G BOARD: IC643, R661
I ABL
Step 3
Record the voltage between TP85 and ground.
1) Using Variac, apply AC input voltage: 130 + 2.0 VAC (or 220.0 ± 2.0 VAC for 34SL40C/34VL65C/37VL65C only) 2) Input a monoscope signal.
Step 4
Using an external DC power supply, apply voltage between TP85 and ground. Increase the voltage gradually and confirm that the holdown works (raster disappears) at lower than the voltage recorded in Step 3. 3) Set the PICTURE control and the BRIGHT control to initial reset value. 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.
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)

The symbol display is on the component side. The components identified by shading and mark are critical for safety. Replace only with part number specified. The symbol indicate fast operating fuse. Replace only with fuse of same rating as marked. Les composants identifiés per un tramé et une marque sont critiques pour la sécurité. Ne les remplacer que par une piéce portant le numéro spécifié. Le symbole indique une fusible a action rapide. Doit etre remplacee par une fusible de meme yaleur, comme maque.
