Do Not use any cleaning product containing alkaline/acid cleaner, scouring powder, or volatile solvent, such as alcohol, ammonia,

benzene, thinner or insecticide. Using any of these harsh cleaners may result in permanent damage to the screen.

Do Not spray water or detergent directly onto the TV screen . If liquid drips into the bottom of the screen it may cause a failure.

LIMPANDO PAINEL DE LCD

5. CAUTION: When cleaning the TV, be sure to unplug the power cord to avoid any chance of electric shock.

6. Clean the cabinet of the TV with a dry soft cloth.

7. Wipe the LCD screen gently with a soft cloth.

8. " Stubborn stains may be removed with a cloth slightly moistened with a solution of mild soap and warm water.

9. " If using a chemically pretreated cloth, please follow the instruction provided on the package.

10. " Never use strong solvents such as a thinner, alcohol or benzine for cleaning.

11. " Periodic vacuuming of the ventilation openings is recommended to ensure to proper ventilation.

CUIDADO COM A SEGURANÇA

TENHA CUIDADO AO MANUSEAR O PAINEL LCD

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

When installing the LCD panel on a 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. Disconnect the AC power when replacing the backlight or inverter circuit. (High voltage occurs at the inverter circuit at 650Vrms.)

7. Always clean the LCD panel with a soft cloth material.

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

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

10. During the repair,

DO NOT leave the Power On for more than 1 hour while the TV is face down on a cloth.

SEÇÃO 1 - SEGURANÇA E CARACTERÍSTICAS

VERIFICAÇÃO DE SEGURANÇA

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.

TESTE DE FUGA

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 microamperes). Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA WT540A. 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.

4. 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).

COMO ENCONTRAR UM BOM ATERRAMENTO

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).

These updates are for enhancements or improvements that

have been made to the software after the TV was released.

ATUALIZAÇÃO DE SOFTWARE PARA CONSUMIDOR

The subject of software updates is a very important. The televisions of today have advanced to the point where they are not simply a television anymore. They are evolving into devices that are designed to integrate with numerous other devices found in the home. Some examples are: Portable audio and video devices, still cameras, home computer networks and accessing the internet to name a few.

Communications with these varying devices requires that the television be compatible with varying communications protocols. Although standards are detailed for each of these protocols, the real world dictates that occasional errors may occur that could prevent devices from operating or communicating properly.

Keeping the software in the television up-to-date is a procedure that is normally handled by the owner of the television. Most customers who own computers and other digital devices are familiar with and are accustomed to updating the software in their products. If a customer contacts the Sony Customer Support Center and it is deemed to be correctable with a software update, the issue is handled at the customer level.

RESPONSABILIDADE PARA ATUALIZAÇÃO DO SOFTWARE

Software updates are designed to be performed by the customer. Warranty repairs in which the issue can be resolved by a software update are not reimbursable. Most issues involving software updates are handled by the customer service center and should not be directed to an authorized service center. It is the responsibility of the servicer to prevent service calls for issues that involve software updates.
