Note: The basic configurations of the main boards (ie. boards including signal processing ICs) are generally common for all types (the sole difference is whether or not all
functions are incorporated in a single chip).
The following presents the methodology used in determining locations of faults, and of repairing those faults. All faults listed below which are due to blown fuses, soldering
defects, FFC connection defects, and FFC defects must be repaired.
