6781QCH038C is the correct replacement.
There is another replacement part for LG's ending with 060Q. Electronia-USA.com stated it may not work with LG's but does work for Vizio's
Yes, a non pro can do this repair.

The Lg you have actually has three boards that can cause the problem you are talking about. The control board, the y-board or the z-board. Usually most technicians will change the y-board and z board together since it is usually a combination of both that cause the problem. The control board by itself can cause the problem. The part #'s are as follows and these are straight from the LG plasma tv training manuals. 1- Control board 6871QCH053G, 2- Y board 6871QYH036D, and the Z-board is
6871QZH041B. The boards can be checked by looking at the voltages and signals but as I said some of those problems for no picture interrelate between boards. Hope this helped. Also with the back cover off those boards are clearly marked. The y board is a small board on the left and the Z board is on the right. The control board is of course in between them. They have tiny white stickers with the part # and assy# on them an also directly on the board itself. Always disconnect the power cord when looking at the inside by taking the back cover off.

Yes you need to replace the board LG 6871QYH048B. The board has a short. Check the fuses and one of them should have no continuity
because it is open.
Replace that board and problem solved
