Dongdong: why does the touch screen don't shine after the boot?

Longlong: the touch screen is not bright, there are two possibilities. One is the fault of the touch screen itself. The two is that the power supply can not be supplied to the whole machine.

1. if it is the fault of the touch screen itself, then after the start of the machine, other functions may be in operation, such as hearing the sound of the fan, the breathing lamp will also light, and hear the "beep". If this is the case, the instrument needs to be returned to the factory for repair.

2. if the power supply is unable to supply power, there is no reaction after the machine opens (the breathing light is not bright, no "beep"). At this time, first check the power plug in the rear of the machine, whether the plug is plugged in, or whether the fuse in the socket has been fused. If the fuse is blown, the fuse should be replaced. There are two spare fuses in the original packing box.


            Operation steps            

Pull out the power line to ensure safety - to use a screwdriver to pry open the socket cover, to pry out the red plastic piece, to take out the fuse to see if the fuse is broken, or to use the multimeter to measure the resistance or not to break. If the fuse is broken, change the fuse, assemble the socket, and open the machine to see if the fault has been solved. If the fuse is good, the instrument needs to be repaired.

Remarks: when taking out the red plastic parts, mark them well and prevent them from being put into fashion.
