• See page 32 for IC Block Diagrams.
Note 1: When the MAIN board is replaced, format it according
to the “NOTE OF MAIN BOARD REPLACING” (refer
to page 4) of the servicing notes.
Note 2: IC501, IC503, IC508 and IC509 on the MAIN board cannot ex-
change with single. When IC501, IC503, IC508 and IC509 on the
MAIN board are damaged, exchange the entire mounted board.
