What are the main causes of motherboards of smartphones damage?
As we know that motherboard is the heart of phone just like as a CPU of computer through which it runs. Motherboard repair and replacement on the other hand is usually very expensive. An electrical spike or surge is a short-lived burst of energy in an electric circuit. This can be the result of power hungry appliances, problems with wiring or problems with the power service outside the house. This Sudden change of voltage can cause damage to the delicate circuits in your motherboard.Another phrase for the same thing is "main board". Essentially, the motherboard is the main circuit board in a mobile phone: the part that contains the most important components, for example the memory and the central processing unit. The motherboard is the computer, so the usual symptom of a failed motherboard is a completely dead system. Fans, drives, and other peripherals may spin up if the motherboard is dead, but more often nothing at all happens when you turn on the power. No beeps, no lights, no fans, nothing.
