connections. Check the entire board surface for solder splashes
and bridges.
2. Check the interboard wiring to ensure that no wires are 5.
"pinched" or contact high-wattage resistors. 6.
3. Look for unauthorized replacement parts, par-ticularly
transistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
EFI eee

Flexible Circuit Board Repairing
* Keep the temperature of the soldering iron around 270°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
