That could be a T-Con board failure. If you can change channels, turn up the volume etc, then it could be the T-Con.

Bogus inverter board which powers the leds for backlighting.

My MKS had this exact problem earlier this year. I took it in and they ordered and replaced the buttons. It worked fine for about three months and now is starting to act up again. Have you gotten any definitive answers?

Most likely the set (in its menu) is set to SAP or secondary audio program==this is for channels that offer simulcast of programs in English or Spanish etc.

Look for the setting and if SAP is highlighted try to select Stereo.

LG TV'S ARE SOFTWARE UPDATEABLE. UNFORTUNATELY, THIS MEANS A TRIP TO AN LG SERVICE CENTRE.

Have you tried changing the batteries?

hello, it look like the volume and channels micro swichs at the front of thr tv.
are broken, you should change all off them

try to increse the volume centre channel level so that u could hear better vocals. or do one thing if u r connected with optical cable only. just connect single RCA cable from dvd players centre channel output to the TV input (Left/mono) so that u can only hear the center channel volume thru TV and all other from speakers even the LG is working..
