1-1. Warnings and Caution

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

2)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.

3)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.

4)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.

5) Components identified by shading and ! mark on the 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.

1-2. Caution Handling of LCD Panel

When repairing the LCD Panel, make sure you are grounded with a wrist band. When repairing 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 power 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).

10)During the repair, DO NOT leave the Power On or Burn-in period for more than 1 hour while the TV is face down on a cloth.

Figure 1. TV is faced down on a cloth during repair.

	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

1-7. Lead 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 4: LF Logo

Figure 5: 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.

1-8. Handling the FLEXIBLE FLAT CABLE (FFC)

When you insert / pull out FFC, please grasp a reinforcement board and main body of FFC.

Please hold reinforcement board and plunge it to depths.
