Panasonic cd/cassette 110v surplus fron japan po ito...

ito mga major parts ginamit:

Audio ic = LA4645
Power supply reg ic =BA3932
Power cont, mute, standby ic =LA5605

Bale ito ang history:

Unang dinala sakin ang unit nasaksak sa 220v, nagawan ko ng paraan at tumunog ulit ang unit un nga lang sorround na lang gumana kc nadale ang sub-ampli inside LA4645.. Binalik ko sa may-ari ang unit sa ganung sitwasyon at pinabili ko siya ng audio ic sa raon. Ngayon andito na ang parts, sinabi niya na nasaksak ulit sa 220v ang unit at umusok pa ;D kinabit ko nalag ung ic kahit may letter dulo (LA4645N instead of LA4645), wala akong choice un ang binili nya... Pero walang lumabas na audio kahit e-finger method...

although kumpleto lahat vcc ...

ito mga mapa...  LA4645_datasheet <=click me
                        LA5605_datasheet <=click me
                        BA3930_datasheet <=click me


Napansin ko lang meron 5v dito sa mute pin ng LA5605,, if naka mute ito paano kaya ito madaya mga sis? Pa help po mga audio masters!!! TIA

I-hang mo yung mute sa 5605 at yung mute pin ng 4645 ilagay mo sa ground.

sis nag nasaksak uli sa 220v at umusok, nakita mo ba kng ano ang nasira? baka my naputol na pcb board o kaya ito ang dahilan na wala kang makuha na audio sa main amp mo..

tanong ko nalang din ito mga sis,, meron na ba naka-try sub nito LA4645N instead of LA4645 ?
duda din ako na sa audio ic pa rin to.. wala daw kc makuhang LA4645 lang....

meron LA4645 sa newport. 750 pesos. kung sakali na maayos mo na yan ay lagyan mo na ng varistor pra sa susunod na masaksak uli ay varistor na lng masisira.

yup! sana maayos pa to ;D... sinong makapagsabi if pareho lang ba LA4645N at LA4645 kasi may kamahalan presyo,,,
pansin ko lang din, pagpindot ko sa-vol at +vol walang beep na marinig d gaya sa ibang buton like cd, band am/fm tuning up/down at iba pa na may key tone.... may tama na kaya syscon?
