Several keys adjacent to the keyboard cannot be pressed

The keyboard is used all the time, and suddenly the next few keys cannot be pressed.

The possibility of damage or contamination at the same time is very small, possibly due to the circuit board partial line rupture caused. The keyboard back cover open, with universal table detection, found that the printed circuit board has a very fine fracture, resulting in a partial circuit breaker, resulting in a number of adjacent key damage. Can be welded with a soldering iron, reinstall the keyboard, the fault can be resolved.
