SOURCE: LG 42LC7D-UB, Bad LCD Controller Board????

Steve, that was awesome. Thanks a bunch. I already have the tools and I can get the solder easy enough. Thanks a again. I went to Best Buy this weekend and all they could say is that the entire board would need to be replace and that they really recommended a new tv as the cost for the new board would be as much as a new TV.... :( typical of them!

The power on problem is a cap in the power on circuit. The loss of signal for an areal is delayed. Nothing you can for DIY.It needs repair shop visit.

Cuts off


Most likely the power supply board.

Lie the tv down on a bed and unscrew the back. Its only about 9 screws around the edge and look at the power board, on the left, see if theres any burn marks.

I have a brand new board I bought the other day for the same issue but before I replaced it, stupidly, I checked with LG and turns out mine is still under warranty so I'm stuck with a new board.

Let me know if you want it. I'll match any price you can find online.
