Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard. • Wear safety goggles when you replace the CRT. Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to the followingpoints: • General repair instruction: as a strict precaution, we advise you to re-solder the solder connections through which the horizontal deflection current flows. In particular this is valid for the: 1. Pins of the line output transformer (LOT). 2. Fly-back capacitor(s). 3. S-correction capacitor(s). 4. Line output transistor. 5. Pins of the connector with wires to the deflection coil. 6. Othercomponents through which the deflection current flows. Note: This re-soldering is advised to prevent bad connections due to metal fatigue in solder connections, and is therefore only necessary for television sets more than two years old. • Route the wire trees and EHT cable correctly and secure them with the mounted cable clamps. • Check the insulation of the Mains/AC Power lead for external damage....
