What is a good site / channel / video course / blog about elementary repair of computers and peripherals?

Question

Do it yourself

Hello!
Please advise some resources for beginners, where in a simple and understandable way, on the shelves, it is told about elementary self-repair of computers and peripherals?
For example, I had a mouse, the wheel began to scroll - I unknowingly threw out the mouse. And you could just tighten the contacts.
Now the wire at the base of the mouse itself is moving away and the mouse stops working.
You have to solder and look for the problem.
It seems to be simple and interesting, but I do not understand it.
Also, for example, about charging cords, headphones, etc.
Thank you!

I think they will be interesting - itoinfo, compsmaster, etc. In general, what prevents in Google / search on YouTube to type how to fix the mouse wire?
