YAY!! fixed it. I learned how to Solder too.
Thanks all for the Wonderful tips and guidance.
These are the things I bought from my local electronics store,
Elenco Soldering Tool Kit - ETL Approved ST12ETL - Micro Center eToolscity Helping Hands 267070 - Micro Center
I got help from my son to hold flash light and hold the tiny wires while I desolder and solder it back. He enjoyed working with me and fixing the camera.
Soldering I wouldn't say it's best but for now it's holding up.
I have to open and close the camera at least 3 times.
First time I opened, Desoldered, soldered, then put the body together without much screws to just test the camera.
Next with all the excitement I put in all the screws that I put on my camera drawing paper to find out I have one screw left that said inside camera.
So opened the camera again, but brilliant me, didn't map where that one screw would go, so wasted time in figuring out and watching Youtube videos. Finally found the spot and assembled everything together.
Testing all the camera buttons to see if everything works as it should, nope the left side focus lever while turning from AF-A to C got stuck at MF. Crap, I have to open the camera all over again.
While opening I got a whirrr shock from the camera, not pleasant lol. Fixed the lever and put everything together, working good so far.
For an experienced person it would have took max 30 min to open and fix it. I started at around 9 PM (after practicing soldering on an old computer exhaust fan wire) and finished by 3 AM (with that many times opening and closing the camera).
This morning it seems to work fine with the Fully charged OEM battery. First short exposure turned out spot on.
Going to further test this evening.
Was going to take a time lapse video but it was too late and I wasn't sure how well the operation will turn out.
Will post pics when I get a chance.
