Question about LG 47LC7DF 47 in. LCD HDTV
Replaced T-Con Board All worked initially Then no picture at all when cover is placed on Now will not work with both ribbons seated, only one or the other
The issue may be inside the display panel or very near it---try very gentle probe of cables with back off and set on----careful!

Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:

Just read the description of your problem and without being there with measuring tools;
The power supply estimate sounds like a fair evaluation of the problem in your model.
Good luck with the repair.

Testimonial: "sounds good thanks"
What about the sound? Do you still have sound when the image is flickering. God help the guy who replaced the T-con though. It sounds like a power supply or inverter issue, provided sound is not affected.

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!
