I picked up this TV and wanted to know if this is a bad panel or bad tcon board. Click on the link to watch the video.

Panel seen this a few times before.
If you take it down to the panel. Your problem isn't the top ribbon connections it actually the ones on the side. They don't actually connect to anything but for some reason, probably heat related they can distort the picture.

I had a Samsung LN32C450D 1G doing something similar. My upper screen was faded and the bottom about the same width showing good picture. Tried a new T-CON and that didn't work...So I went with bad panel diagnosis.
However I am looking for a main board for a LG 47" if you are scrapping for parts.

What's the part number? I can check my bins when I get home tonight.

I concur, panel.

The little things hanging out the edge of the panel aren't useless - they're the gate drivers. They get their drive signal through the LCD glass itself and chain the signal to each IC. If they go bad you will see something like this usually only affecting 1/4 of the screen.

Thanks tom66. I guess this TV is scrapped for parts.

Cheers Tom, always wondered what they were for. Googled it before but didn't really get an answer.

Learn something new every day on here.

I'm seeing a trend with LG panels with this problem.
