Page 3: Safety-Related Component Warning
KDL-22BX325/32BX325/32BX326/32BX425/40BX425 SAFETY-RELATED COMPONENT WARNING There are critical components used in LCD color TVs that are important for safety. These components are identified 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 specified in the electrical parts list to prevent electric shock, fire, or other hazard. - Page 4 KDL-22BX325/32BX325/32BX326/32BX425/40BX425 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.
