Re: LG 42LGX Mystery Part- at least to me;-)
The above worked for me, had a TV with the same board and the same symptoms (horizontal static lines) and after swapping over the 100uf 16v smd caps its now working properly.
I only changed the ones you can get at without removing the soldered on cover part (missed a few around the edge under the metal cover)
Unfortunately I didn't test the replacements one at a time so can't narrow down any further any specific ones that need replacing.
