Hello everyone, I have problem that I didn't find solution for on Internet, so hopefully I will find someone with electronics background in here who can help me.

I have Logitech g100s Mouse and at start Left click was making me problems, so I tried to fix the spring inside microswitch, but once I opened the microswitch I broke the spring.

So ordered new micro switch, unsoldered old one and soldered new one (I had to learn to do this process from beginning ordered soldering iron, flux, tinol, multimeter), I thought my problem were solved now that I had new left click in micro switch in place, I put my mouse back together only to find out my mouse isn't working at all! Like it wont even move, work on any click or anything, and in windows it says my hardware cannot be recognized.


Newly attached left click, I didn't break the circuit or anything.

Only problem I could think of why it act like this is, that during my mouse disassemble I unplugged USB cable from the mouse board, and it pulled mouse board Pins up, from the mouse board. So I returned them in and put them in place all pins are same height.


Here you can see second PIN (from left to right) were more down than the others, but I fixed it by unsoldering it and moving it slightly above so it all stays in same height line.

Now the things that I don't fully understand are, that I have little break on one of the red lines shown in picture below;

I checked for continuity test with multimeter, there isn't any connection between these two pins where line breakage is.

I set apart another mouse which had 5 PINS too, and I check for continuity test between each of PINS and there were not any connection. But on my logitech mouse, I tested positive on continuity test between (PIN 1 and PIN 2) - Thick Black cable and skinny black cable.
Color of wires are: Thick black, skinny black, Red, White and Green.


I want to thank to everyone who reads this message, even if you cannot help me, I appreciate your time of every single one of you.
 
Hello. I always appreciate anyone who can fix things or at least attempts to do so.

Unfortunately too many products these days are being made to be unfixable and even damaged if a repair attempt is made.

Your description of "events" pretty much demonstrates the same.

Circuit boards are getting so flimsy and now have such fine traces that breaks can easily happen. The same holds for any chips and components - soldering obviously generates heat so any nearby components can get damaged. All low quality below any fixable, board level repair.

Even products from just a couple of years ago have stronger, more substantial circuit boards.

You have made a pretty good go of it but there is a point of dimishing returns.

You may succeed in a fix which would be good but in all likelihood some other component, solder connection, trace will fail. Won't take much as the mouse is overall a "moving part".

Probably time for a new mouse......
 
I will try to go to electronics repair store and try to ask someone who have experience with these to hear his opinion, if its dead well, at least I did my best to try repairing it.
