Important Safety Notice Special components are used in this television set which are important for safety. These parts are identified on the schematic diagram by the symbol and printed in BOLD TYPE on the replacement part list. It is essential that these critical parts are replaced with the manufacturer’s specified replacement part to prevent X-ray radiation, shock, fire or other hazards. Do not modify the original design without the manufacturer’s permission.
About lead free solder (PbF) Note: Lead is listed as (Pb) in the periodic table of elements. In the information below, Pb will refer to Lead solder, and PbF will refer to Lead Free Solder. The Lead Free Solder used in our manufacturing process and discussed below is (Sn+Ag+Cu). That is Tin (Sn), Silver (Ag) and (Cu) although other types are available. This model uses Pb Free solder in it’s manufacture due to environmental conservation issues.

Service Notes Note: These components are affixed with glue. Be careful not to break or damage any foil under the component or at the pins of the ICs when removing. Usually applying heat to the component for a short time while twisting with tweezers will break the component loose. Leadless Chip Component (surface mount) How to Replace Flat-IC Chip components must be replaced with identical chips due to critical foil track spacing. There are no holes in the board to mount standard transistors or diodes.
Service Notes (Continued) IMPORTANT: To protect against possible damage to the solid state devices due to arcing or static discharge, make certain that all ground wires and CTR DAG wire are securely connected. WARNING: This Receiver has been designed to meet or exceed applicable safety and X-ray radiation protection as specified by government agencies and independent testing laboratories. CAUTION: The power supply circuit is above earth ground and the chassis cannot be polarized.
