RM-GA011

SECTION 1

SAFETY NOTES

1-1. Caution Handling of LCD Panel

When installing the LCD Panel, make sure you are grounded with a wrist band.

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

1)Do not press 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 temperature 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 short circuit within the module.

6)Disconnect the AC adapter when replacing the backlight (CCFL) 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 circuit.

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

1-2. 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 contact high-wattage resistors.

3)Check all control knobs, shields, covers, ground straps and mounting hardware have been replaced. Be absolutely certain 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 test as described next.

1-3. 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 0.5mA (500 microamperes). Leakage current can be measured by any one of the three methods:-

1.A commercial leakage tester such as the SIMPSON 229 or RCA WT-540A. Follow the manufacturers instructions to use those 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 0.75V 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 2 VAC range are suitable. (see FIGURE 1)

1-4. WARNING !

SAFETY-RELATED COMPONENT WARNING! COMPONENTS IDENTIFIED BY SHADING AND MARK ! ON THE EXPLODED VIEWS 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.

1-5. LED Free Information

The circuit boards used in these models have been processed using Lead Free Solder. The boards are identified by the LF logo located close to the board designation.

Figure 2: LF logo

Figure 3: LF logo on circuit board

The servicing of these boards requires special precautions. It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality of new solder joints. Lead Free Solder is available under the following part numbers:-

Due to high melting point of Lead Free Solder, the soldering iron tip temperature needs to be set to 370 degrees centigrade. This requires soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.

Components not identified by a part number or description are not stocked because they are not required for routine service.

The component parts of an assembly are indicated by the reference numbers in the far right column of the part list and within the dotted lines of the diagram.

Item marked with an asterisk (*) are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these components.

NOTE: The components identified by shading and ! mark are critical for safety. Replace only with part number specified.

Note: The components identified by mark contain confidential information. Strictly follow the instructions whenever the components are repaired and /or replaced.
