Nawala ang echo ng Home karaoke
Ano kaya sira nitong karaoke sa bahay namin? Ito yong pangalan nya = Oclar Karaoke Audio Entertainment, Model= OA-J2800. Gawa yata ito ng Gillamacs. Ang kanyang digital echo IC ay M65844P (dalawang echo IC). Natingnan ko na ang Vcc ng ICs at meron itong 5 volts na supply. Meron itong Echo Level, Echo Repeat, at Echo Rating. Please help. TIA

Re: Nawala ang echo ng Home karaoke
tumutunog ang microphone pero wlang echo?
my echo pot ba ang unit mu? paki check bka my putol
maaaring sira ang echo ic mismu. mas mainam
check muna rin lhat ng peripheral parts niya sa paligid lalo na ang capacitor at resistor bago palitan (^_^
