It might be na overloaded ang tuner or too weak ang signal...malinaw ba ang reception mo? if malinaw ang reception..try mo gumamit ng indoor antenna or kahit wire lang muna..

para kasing di gumaga ang ACC ng unit...

according to you the video is ok but black & white,i am right?medyo may tama ang tuner dhl affected ung video/audio(IF) section,means d maganda ang rf output.by the way,pag naka audio/video in ka,selected ba ung pal or ntsc?pag gumagana yan sa pal eh dapat mapalitan ung x'tal nya to convert into 3.58 dhl un ang standard signal dyan sa pilipinas.try to get a diagram for quick and easy troubleshooting.thanks and goodluck.....
