[Q] Kindle fire 1st gen unused TFT port? - Kindle Fire Q&A, Help & Troubleshooting

Hello XDA Developers! This is my first post, so if i am doing anything wrong, please inform me
I have had my kindle fire motherboard sitting on my desk for a while now, and I have noticed an unused port near the top. I just so happen to have had a 40 pin TFT LCD panel next to it, and noticed that the unused port is also 40 pins, and has the same layout. Anybody have any idea what this was for?

it's the secondary microphone, used for noise-canceling when making phone call or recording video. Most of the phone today has 1 main-microphone and 1 noise-canceling microphone. Some have more

Wire cord replacement

I have an 8.3 that has its wire cord broken. For reasons, I need the exact cord replacement. LG does not sell it. I can't find one while googling or maybe I just have weak google-fu. Can anyone point me where to buy it? Does anyone here do?
Photo below is a screencap from a site selling the tablet with this cord.

Display Issue on J6+

Hi Guys, it's been a while since i have started seeing that white patch on my phone's display. Sometimes it goes all the way up and covers about 3/4 of screen. But here's a thing, when i give a lil bit heat to display (with heatgun, blower or whatever) these lines and patches just disappear. Is this a hardware issue or something else? Please help
