ADJUSTMENT
4.1
PREPARATION
4.1.1 Precaution
This model is specially adjusted by using PC.
However, if parts such as the following are replaced, an
adjustment is required. The adjustment must be performed in a
Service Center equipped with the concerned facilities.
• OP BLOCK ASSEMBLY
• MONITOR ASSEMBLY
• EEP ROM (IC1003 of MAIN board)
In the event of malfunction with electrical circuits, first find a
defective portion with the aid of proper test instruments as shown
in the following electrical adjustment procedure, and then
commence necessary repair/ replacement/adjustment.
• In observing chip TP, use IC clips, etc. to avoid any stress.
Prior to replacement of chip parts (especially IC), remove the
solder completely to prevent peeling of the pattern.
• Since connectors are fragile, carefully handle them in
disconnecting and connecting the FPC.
4.1.2 Required test equipment
