of circuit. This IC is a DC-DC converter for power supply voltage. Following sections include information on the IC type &
method to identity for service repair.
1.1. Change of IC type (IC2002)
This section describes the necessary information change of IC2002 on the Main P.C.B. Figure 1 below shows the location of
IC2002 (DC-DC Converter).
Purpose : IC2002 changed from discrete type (through hole) to surface mount type (Ref to Figure 1 & 2 for diagram).
Result: this leads to modification of Main circuit (power section) & removal of parts. (section 1.3 shows the main circuit modification.
Hence it is very important that the correct type of IC is used for the correct version of Main P.C.B.
