Sony HCD-RV222DA namamatay

Post by Lenaren on Tue Mar 17, 2015 1:03 pm

Patulong naman po kung paano i-troubleshoot tong Sony component na to... pagsaksak mo po ganito po ang display ang nalabas "--:--" tapos mamamatay na... pag-ipress mo power button lalabas saglit ang display tapos mamamatay din agad...

Sinubukan kong i-hang ang supply pin (VCC+) ng IC (STK433-130 pin3)... pagsaksak mo tulad din po ng dati... pag-ipress mo ang power button may nalabas na "PROTECT" po sa dispaly...

Ano problem nito master? Audio IC na ba to? Salamat po...
