Check mo yung audio signal sa swicting IC pabalik sa tuner. mas maganda pagganyan ang trouble ay may schematic ka para masundan mo yung flow AF to audio..

hintay natin mga master dito..

malamang may sound yan kasi ok sa AV malamang setting lang talaga yan check mo din ang audio setting sa service mode. note mo ang data bago ka magpalit ng settings
