<p><b>New page</b></p><div>Hi,<br />
Do you mean the LCD cannot light up?<br />
<br />
Answer:<br />
<br />
This screen need configuration to be work. GPIO18 should be connected to the 12th pin of ４０ＰＩＮ.<br />
<br />
And should add<br />
<br />
gpio=18=op,dh,pd<br />
<br />
in the config.txt.<br />
<br />
Sudo raspi-gpio set 18 op dh turn on the backlight<br />
Sudo raspi-gpio set 18 op dl turn off the backlight<br />
<br />
Best regards,<br />
