Re: Emerson ltdn42v68us, 42" LCD, picture goes out, has sound
Glad to see this post helped folks. I actually just came back to look up the model number for this thing to find the owner's manual.
My quick fix is still holding up... knock on wood... so the 2010 Wal-Mart special lives on.
A couple notes on this:
1) Once the cable burns up, it's not replaceable... the burning-up process destroys the connector at the board, so only fix is basically what's outlined above. For mine, the destruction was just at one end, so I desoldered the connector at the board.
2) Sorry I didn't take pics of the back; didn't think to, and the color of wires I used was arbitrary (again, left over from rewiring my truck). If you understand how circuit boards look (and work) you can follow the traces on the underside of the board, and solder in to good spots. It's fairly obvious where once you remove and flip the board over. TA->TA, GND->GND, TB->TB... 5,2,5 wires.
3) A better fix would have been to have completely removed the cable and replaced the complete wire with 16 gauge from 1 board to the other (rather than patch it in like I did.) I didn't because frankly I was too lazy to do it that way, figured that the higher resistance was on the main board end, and that if it ultimately burned up again I'd fix it, again, by replacing the other end.
