MAIN BOARD (Component Side) SECTION 1 SERVICING NOTE Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C dur- ing repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be care

12、ful 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 dam- aged by heat. S102 on www.freeservicemanuals.info15/12/2014 Digitized in Heiloo, Hollan
