I'm also glad you didn't give up Budm. It's nice to see results rather than the individual becoming frustrated and giving up.

Yeah, I am glad to be able to narrow it down to the T-CON instead of the main board.

*whew*

Well, what did you think happened? When I put the new TCON in, I mustve not inserted the 2 strips in all the way into the panel, so I immediately posted the result here.

I went for broke and redid it all. Snow, glorious snow on the screen.

I intend to update the 1st post with the solution plus what I've learned from this.

Thank you all so much. I learned so much from this experience, mostly to take your time and use a magnifying glass.

EDIT: I guess I can't edit the first post. budm, dick_barton, diah, capleaker, and anyone else I missed, thank you so much for help me save the TV from the dump. I'm very proud of this!

WAIT! Oh man! I spoke too soon!! Hold on...

Re: LG 47LN5200_U: PWR, MAIN, and all LEDs replaced, no picture

Something is not right!!!!!!!
Do you flip up the tabs on the ribbon connectors to insert/remove the cables and then click them back down to lock the cables in place or are you pulling /pushing the flat cables into place???

Re: LG 47LN5200_U: PWR, MAIN, and all LEDs replaced, no picture

So you still have 12VDC at the F1 fuse of the NEW T-CON but no DCV on any of those test points?

Re: LG 47LN5200_U: PWR, MAIN, and all LEDs replaced, no picture

TCON arrived, no change to the TV. Man...

This leaves the LVDS cable and the panel I guess.

If you can provide feedback after fitting the replacement Tcon would be good.

Absolutely.
