Cabinet (Rear) Main Board DIAL POINTER INSTALLATION ADJUSTMENTS... 5 Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 70 C during repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat. 5.
