1. SAFETY & PRECAUTIONS
SAFETY CHECK AFTER SERVING Examine the area surrounding the repaired location for damage or deterioration. Observe that screw, parts and wires have been returned to original positions. Afterwards, perform the following tests and conform the specified values in order to verify compliance with safety standards. 1-1. Insulation resistance test Confirm the specified insulation resistance between power cord plug prong and externally exposed parts of the set (video and audio input terminals, speaker out terminals etc) is greater than values given in table 1 below. 1-2. Dielectric strengthen test Confirm specified dielectric strengthen between power cord plug prongs and exposed accessible parts of the set (video and audio input terminals, speaker out, etc) is greater than values given table 1 below. 1-3. Clearance distance When replacing primary circuit component, confirm specified clearance distance (d), (d') between soldered terminals (see Fig1), and between terminals and surrounding metallic parts.
