Newman MP4 has 2 LCD screens, each screen has an independent LCD interface circuit . There are relatively few electronic components on the LCD interface
circuit ,
and it is easier to detect.
For the LCD screen to work normally, in addition to the signals transmitted from the CPU and the decoding chip, the LCD boost circuit is also required
to provide power to the LCD screen. As shown in the figure, the LCD backlight boost circuit is shown. The MP4 machine's backlight boost circuit
is
composed of two small integrated circuits U4 and U6.
