Question posted by ronaldfarah on June 25th, 2011

I Have Lg Sh92sb Audio System And The Audio Outputs Are Not All Working.

home audio system LG SH92SB. All three audio outputs on one side are working fine (Front Left, Front Right, and Subwoofer) but the three outputs that are on the other side are not working (Back Left, Back Right and Centre). I made sure that all speakers are working fine by testing them one by one on the outputs that are working. I even opened up the box to check if maybe each three are on a separate circuit with a fuse, I did not find any fuses other than the one for the AC power, I did not mess with it any further... so please help :) Thank you in advance, Ronald

Sounds like a blown amplifier. The amp is split between two sides to provide stereo sound output. Either the processor that feeds the audio into the final amplifier has died or one channel of the amp itself has died.

Best bet is to take it to a service shop for a full diagnosis.
