HCD-G100K ang nakalagay sa likod, sa harap naman ay may LBT-G100K. Sa CD Player mayroong sound, sa AM FM wala po siyang sound.

sa mga pioneer ang usually na nasisira
ay yung mga ceramic filter
at mga coils, bihira ang supply
since sony ito try mo mag smula sa supply
kung may scope ka mas maganda, pede mo
ma trace signal

inject inject lng sa in at out ng bawat section. pgtumunog pkanan ka.
kng di naman paurong ka pakaliwa (^_^

pwede ring gumamit ng small amp para sa signal tracing. yung input ng small amp ay didiritsa mulang iconnect sa mga pins ng ic... but be careful sa mga pins na present ang malalaking voltage.
