ito pasok ka dito...
http://www.electronicslab.ph/forum/index.php?topic=2267.140

bago ka mag attempt mag bago ng data.. ilista muna sa malinis na papel ang orig data parameter.. para kng sakaling may mali sa pag-aadjust mu.. pwde mu pang ibalik sa default settings...

but takenote di ko pa nirerefer sau ang service mode as long na di mu pa sinusubukan ang suggestion ko sa taas.. at ang gustong ipagawa sau ni sis HG

how about sa AV mode ?
wala din bang sound ?

dahil nag attempt kang i direct ang from jungle/UOC to Sound ic.. dapat dinisable mu  muna ang Mute pin at siguraduhing di naka standby mode ang sound ic mu...

yan  nlng  muna.. .gudlak
