SAFETY-RELATED COMPONENT WARNING
There are critical components used in LCD color TVs that are important for safety. These components are identifi ed with shading and 
!
 
mark on the schematic diagrams and the electrical parts list. It is essential that these critical parts be replaced only with the part number 
specifi ed in the electrical parts list to prevent electric shock, fi re, or other hazard. 
NOTE: Do not modify the original design without obtaining written permission from the manufacturer or you will void the original parts and 
            labor guarantee. 
USE CAUTION WHEN HANDLING THE LCD PANEL
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. 
To avoid damaging the LCD panel:
 do not press on the panel or frame edge to avoid the risk of electric shock.
  do not scratch or press on the panel with any sharp objects.
  do not leave the module in high temperatures or in areas of high humidity for an extended period of time.
  do not expose the LCD panel to direct sunlight.
  avoid contact with water. It may cause a short circuit within the module. 
  disconnect the AC adapter when replacing the backlight (CCFL) or inverter circuit. 
(High voltage occurs at the inverter circuit at 650Vrms.) 
  always clean the LCD panel with a soft cloth material.
  use care when handling the wires or connectors of the inverter circuit. Damaging the wires may cause a short. 
  protect the panel from ESD to avoid damaging the electronic circuit (C-MOS).

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 e.g. H1 etc [ see example ]. The
servicing of these boards requires special precautions to be taken as
outlined below.
example 1
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 the higher 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.
For more information on the use of Lead Free Solder, please refer to  http://www.sony-training.com
