12 TROUBLESHOOTING GUIDE
12.1. Introduction
At first, check connection of cables and the main power. And then check to find out which part of the system is the cause of the
trouble. Follow the flowchart provided below, and replace each unit in turn with a working unit to identify the damaged unit.
Note:
DO NOT REPLACE IC207.
IC207 (FlashROM) is fixed on the PCB by resin to secure the long-term reliability of soldering joints.
Removing IC207 has a possibility of causing damage to the PCB. In case flowcharts show that IC207 is suspected part, check
the soldering joints first and peripheral parts.
When IC207 is judged defective part(In the case judged "Replace the IC207"), please change the mainboard.
