LG washer doesn’t turn on when touch panel is attached

[playfullyvivid]

I have an LG WT7300CW 01 washing machine. At one point it began to turn on only when it wanted, and recently outright stopped turning on. I took it apart to take a look and deduced that when the front touch panel is attached, the thing would lock up and no longer work.

I figured the issue was the panel went bad so I ordered a used replacement from eBay. Hooking that one up did not solve the problem, and I’m no longer sure what the issue is. I would think the board is the issue, but when I interface with the board without the touch panel, everything works fine.

I took a video showing the issue. In the video, the touch panel is installed and the dial will not work. I quickly uninstall the panel and try to rotate the dial again, but now it works.

This suggests that attaching the touch panel breaks the circuit. I could see that being the issue with the old one, but then why is this also happening with the replacement. Maybe the seller sold me a bad one I suppose, but I wouldn’t know how to test that. Right now we’re using it without the touch panel but ideally would want it fully assembled again.

seems like something is touching the between the board and the UI

Maybe these two videos are the answer. I really don't know. 

In the video with the guy in the black shirt there is a link that skips to the actual fix. 

Hopefully that works
