I heard a "Pop" & the TV went dark & no sound.
I have an LG model# 47LS5700 built & bought in Dec., 2012. I had the same symptoms as above 2 nights ago while watching my 47" Smart LG LED TV, I heard a "Pop" & the TV went dark & no sound. The cable box was still on & the power light on the TV was still on. I walked up to the TV & smelled a burnt odor, so I unplugged the TV. The next day I opened my TV & looked at both boards. I couldn't see any evidence of burnt traces or other burnt parts on the top or back of both boards.
I looked closer with a magnifying glass & I saw a part on the power board that appeared white, not like any other part. I thought it may be damaged/burnt. I lightly touched it with a screwdriver and some of the white part kind of dropped off like dust. I didn't see any other parts like that one, that were white, they were all Blue. I wondered if it could have been Blue like the other similar parts. Do you think it might have been blue and when it heated up [Popped], the blue rubber/plastic cover disintegrated?
I will send photos.
Here are the pics I tried to add last night:
