Common LG LCD TV REPAIR - NO PICTURE OR BLACK SCREEN FIX ... came on good with green light working properlybut still no picture.
Hello A sudden stop of sound output while the set works denotes either its speaker or audio output IC damaged. Check the speaker first by using a multimeter for its voic coil continuity. If speaker is OK, the fault is surely with the audio output IC. It should be replaced with same type and number. It is a semi-skilled work, you have to open your tV, locate the audio output section. You must have knoledge in electronics to do this work. OK.
