STANDARD NOTES FOR SERVICING

Circuit Board Indications

1. The output pin of the 3 pin Regulator ICs is 

indicated as shown.

2. For other ICs, pin 1 and every fifth pin are 

indicated as shown.

3. The 1st pin of every male connector is indicated as 

shown.

Instructions for Connectors

1. When you connect or disconnect the FFC (Flexible 

Foil Connector) cable, be sure to first disconnect 
the AC cord.

2. FFC (Flexible Foil Connector) cable should be 

inserted parallel into the connector, not at an 
angle.

Pb (Lead) Free Solder

When soldering, be sure to use the Pb free solder.

How to Remove / Install Flat Pack-IC

1. Removal

With Hot-Air Flat Pack-IC Desoldering Machine:

1. Prepare the hot-air flat pack-IC desoldering 

machine, then apply hot air to the Flat Pack-IC 
(about 5 to 6 seconds). (Fig. S-1-1)

2. Remove the flat pack-IC with tweezers while 

applying the hot air.

3. Bottom of the flat pack-IC is fixed with glue to the 

BOARD; when removing entire flat pack-IC, first 
apply soldering iron to center of the flat pack-IC 
and heat up. Then remove (glue will be melted). 
(Fig. S-1-6)

4. Release the flat pack-IC from the BOARD using 

tweezers. (Fig. S-1-6)

CAUTION:

1. The Flat Pack-IC shape may differ by models. Use 

an appropriate hot-air flat pack-IC desoldering 
machine, whose shape matches that of the Flat 
Pack-IC.

2. Do not supply hot air to the chip parts around the 

flat pack-IC for over 6 seconds because damage 
to the chip parts may occur. Put masking tape 
around the flat pack-IC to protect other parts from 
damage. (Fig. S-1-2)
