Case:
There is no sound when you turn it down and stop
Solution:
First of all, we replace the circuit board, the fault is still, and then rely on the terminal to deal with the G P table. The fault is still the problem.After turning on the hard disk detection, there is no problem with the head and plates, so we use a simple replacement method to install the magnetic head of the bad disk on the good disk for a good disk.Yes, it is bad and then replaced the magnetic head data. Due to the few Samsung hard disks, many failures are tested by hardware replacement, so it takes a whole day.
