Question about Televison & Video
If it is connected to external speakers, then make sure they are on the correct outputs terminals for the mode you are in. Most TVs have several outputs for speakers. Quickest method is to move them to the other outputs until you get sound.
if they are internal speakers, check your balance settings to make sure they are not accidentally balanced off.

This TV is using a power supply MLT168A that has defective capacitors. Replacing the capacitors might fix it, but in some cases the failure is more then capacitors.

Had the same problem with a new "Insignia" hd set and my Sony receiver. Went to the TV inputs, scrolled thru the selection, which included the HDMI option. Choose it.................problem solved.

Sounds like the digital control board, 6871qch038a Lg Digital Control Module subs to 6871qch038c. But that's just a first something I would check in this unit. Replace also capacitor C19, 630V big blue square cap very common failure for no video. You might want to shop this one thee are a host of problems with this unit that would certainly get some needed attention if a qualified tech were testing it and looked up the bulletins.
