FAQ:
Some users say that there is a bright light at the bottom of the screen when there is no music, and suspect this is a quality problem. In fact, this is not a quality problem, but caused by the user's poor music signal itself. It is usually due to the use of poor power supplies. Including the 12 power supply input of this machine, or digital audio equipment like bluetooth speaker, usb speaker, the frequency of this kind of equipment contains a lot of fundamental noise, and some low-end products can be heard directly from speaker. Judging whether it is external noise is actually very simple, just short-circuit the input terminal to ground, and there should be no display on the screen at this time.
