Solutions to the problems of the red light of Amlogic processors

[Nshat]

I have many TV boxes that carry s905x processors such as x96, mxq and h96 when inserting the 5v port it gives a red flash and does not turn off on HDMI and when flashing it through a device without pressing the button of the REST it works on a device for the unit I hope that my explanation is clear according to the experience
