Nice fix John. My parents had the same issue with theirs, was broken connections rather than the socket being damaged, just reflowing the socket worked a treat.

Tip for getting glue off things like batteries, put ipa on it, it softens it

Smashing repair john :-D
There is no way that socket will come off, solid as a rock.
i watch a bloke called Sorin, he repairs all sorts of electronics, he loves good flux and hot glue.
I've used hot glue to fix the broken laptop casing around power sockets, modern machines are so thin and brittle :-(

Hello John, I don't know how I missed this video - I check regularly. Oh well, better late than never. Great video my friend and the microscope camera was really awesome. Those ribbon cables are so delicate and easy to break. I hope you and your Mum are keeping well. Regards, Dave

Nice work John. It'll be a while before I'm at that level but I'll enjoy the journey :-)
Cheers, John

John - Would it have been useful to temporarily tack down one of the smaller pins at the beginning just to keep them aligned? I don't have a lot of experience with these connectors so it's possible that would put undue mechanical strain on the port...just wondering? Thanks for sharing, great job as usual!

I have a Samsung tablet I believe requires a new battery. I was considering throwing it out, but maybe I'll try and attempt a repair after watching this.

You mentioned that 400C was high for a soldering iron, but I have very poor results with my iron unless I have it set to 350C. What sort of temperature is a "normal" operating temperature, in your experience?
