hi there.its likely that the lower y-drive panel has died.this is a very common problem with this model.the easy way is to remove the panel from the set completely,power it up and you should be greeted with the top half of the picture.this means ic failure,usually the bottom one for some odd reason.not replaceable unless you have the gear,these ics are available from dalbani(nikkai)for those interested.be extra careful with the four ribbon cables when removing/refitting.damage to these writes off the display panel.hope this helps somewhat,regards,steve.

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.

Look on rear to see if a slide switch for internal/external speakers.
Look in menu to see if has a feature speakers on/off.
Put your ear straight to the speaker to see if hear anything; if nothing heard either bad speaker or audio circuit problem.
