WARNINGS AND CAUTIONS - ENGLISH

CAUTION

These servicing instructions are for use by qualified service personnel only.

To reduce the risk of electric shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so.

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.

CARRYING THE TV

Be sure to follow these guidelines to protect your property and avoid causing serious injury.

• Carry the TV with an adequate number of people; larger size TVs require two or more people.

• Correct hand placement while carrying the TV is very important for safety and to avoid damages.

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.

KDL-55W650D UC2/LA1

WARNINGS AND CAUTIONS

USE CAUTION WHEN HANDLING THE LCD PANEL

When repairing the LCD panel, be sure you are grounded by using a wrist band.

When repairing the LCD panel on the wall, the LCD panel must be secured using the 4 mounting holes on the rear cover.

1) Do not press on the panel or frame edge to avoid the risk of electric shock.

2) Do not scratch or press on the panel with any sharp objects.

3) Do not leave the module in high temperatures or in areas of high humidity for an extended period of time.

4) Do not expose the LCD panel to direct sunlight.

5) Avoid contact with water. It may cause a short circuit within the module.

6) Always clean the LCD panel with a soft cloth material.

7) Use care when handling the wires or connectors of the inverter circuit. Damaging the wires may cause a short.

8) Protect the panel from ESD to avoid damaging the electronic circuit (C-MOS).

9)It is recommended not to exceed 1 hour of Power-On nor Burn-in period with LCD panel face down condition, in repair activity.

10)Disconnect the AC power when replacing the parts.(FFC cable etc.).

KDL-55W650D UC2/LA1

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 antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.

8. For safety reasons, repairing the Power board and/or Inverter board is prohibited.

KDL-55W650D UC2/LA1

SAFETY CHECK-OUT

Leakage Test

(To protect electric shock when customer touch the terminal.)

Leakage current can be measured by V: Voltmeter or oscilloscope (r.m.s. or peak reading)

Stabilized power supply instrument and isolated voltage transformer:

Use too much current capacity and isolated voltage transformer does not need to use stabilized power supply equipment

Specification of RMS volt meter: Input resistance > 1 Mohm, Input capacitance < 200 pF,

Frequency range: 15 Hz – 1MHz (Refer Figure 1). Isolated type volt -meter (FLUKE 8921A etc *1)

*1 Not use FLUKE 8920A that connected to protective earth by diode

# Leakage current of measurement instrument is less than 10μArms when under test equipment AC plug is

opened

# Set up the following condition and turn on the set.

Applied voltage: Nominal input voltage (Description on Nameplate)

# Measure the leakage current between one phase conductor and neutral for terminal A and terminal B.

Read rms value, and then calculate to peak value PEAK VALUE =√2 RMS VALUE

Comply with the following requirement Class II equipment (2-pin plug): for each terminal, the worst value of measurement must

not exceed AC 350uA peak). Note: including AC adaptor, AC adaptor/DC operated unit combination

How to Find a Good Earth Ground

A 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).

SERVICE POSITION

2. Remove all screws on the Rear Cover to

Bezel & Main Board & Bracket (23 screws)

1. Remove all screws on the Stand

to main unit (4 screws)

3. After removing rear cover , lie down the main unit

to a surface for following test/repair.

As for this model, the bottom of rear cover is installed between the stand assy and the panel.

Therefore according to the following procedure when performing adjustment and operation check after the part replacement.

Note: Remove rear cover, then assemble the stand to main unit. This

will cause the stand with main unit fit closely, scratch or deformation

may occurred easily on the stand or bezel deco.

Attention: This photo is based on Sony criteria for appearing standing the

main unit after removing back cover and assembling the stand. But

considering mechanical design of Taurus models and normal service

process, it is not recommended to keep main unit standing by this status

for repairing/testing at repair center. Please pay attention for avoiding

possible scratch/deformation occurred.

• Items with no part number and no description are not stocked because they are seldom required for roution service.

• The construction parts of an assembled part are indicated with a collation number in the remark colum.

• Items marked " * " are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items.
