WARNINGS AND CAUTIONS - ENGLISH

CAUTION

These servicing instructions are for use by qualified service personnel only.
To reduce the ri sk o f el ec tr ic s hoc k, d o not per for m any s er vic ing other than tha t c ont ai ned in t he o p er at ing ins tr ucti o ns 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 co mponents are replaced or improper operation is suspected.

USE CAUTION WHEN HANDLING THE L CD PANEL

When repair ing t he LCD p a nel , b e sure you ar e gro und ed b y using a wrist b and .
When repair ing t he LCD p a nel on the wall , the LCD panel must be secured us ing the 4 mounting holes on the r ea r c o ver .

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 temperatur es or in areas of high humidity fo r an extend ed p eri od 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 per iod with LCD panel face d own conditio n, in repair activity.

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

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” o r 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 unauthorize d replacement parts, particularly transistors, th a t were installed during a p revious repair. Point them out to the customer and recommend their replac ement.

5. Look for parts which, though functi oni n g, show obvio us s igns o f d ete r io ra ti on. P o int them out to the cust omer a nd re co mmend 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.

KLV-22P402B/24P412B/24P42 2B (IND/RMD)

Leakage Test

The AC leakage from any exposed metal part to earth ground and from all exposed m etal 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 leak ag e 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 multim eter is suitable for this job.

3. Measuring the v oltage d rop 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 o f passiv e VO Ms that are suitabl e. Nearly all
battery-operated dig ital multimeters that have a 2 VAC range are suitable (see Figure A).

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 y our earth g round , v erify 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

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.

<22/24inch>

1. Remove all screws on the Stand
to main unit (three screws)

2. Remove all screws on the Rear Cover to
Bezel & Main Board & Bracket (nine screws)

3. Afte r removing rear cover , lie down the main unit
to a surface for foll o wing test/repair.

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

main unit after removing back cover and assembling the stand. But
considerin g m ech a n ical desig n of T2 models and norm al service p rocess, it

is not recommended to keep main unit standing by this status for
repairing / t est ing at repair c en ter. Please pay attention for avoiding

possible scra t ch / d ef orm ation occurred.

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.
