Determine a problem on a faulty keyboard and solve it. Video guide

In this video i show you how to find the problem on a faulty keyboard. The keyboard wasn't be able to write.

So after the power check(if the keyboard takes or not power), I realized that it wasn't take power.

What I had to do, was to change the keyboard cable. You should be familiar with a solder iron, solder paste, in order to change the keyboard cable.

See the easy made video guide. Thank you
