Glad this helped! Nice work!

That’s the power button. It just slides into place

Yes that would still be the antenna most likely.

The antenna on these seems to be built into the power button board if I remember right.

Unfortunately, I don't know of anywhere to get it. Sorry about that.

No, sorry. I don’t know of anywhere to buy them brand new.

The only good way to fix this is to get a new connector and solder it onto the board correctly. That’s the only good way that I know of to do it.

@pccheese Hey thank…I do make mine more to help others see how to get them apart & repair them so I’m glad to know that I’m getting there!

TR8 or TR9 work fine. I presonally use a TR8 because I've found it to fit looser and not get stuck in the screw hole. When I'm fixing a bunch of these at a time it makes it much faster if the bit doesn't stick in the screw.

Yes, it's connected to your motherboard. It will need to be replaced if it's not working.
