Suggestions:
① check the power supply of some screens, whether the receiving card is working properly, whether the network of the receiving card is normal.
② If the power supply does not light up, replace the power supply first; if the receiving card does not work, replace the receiving card and resend the program.
③If still can not solve this problem, please contact sales or technical personnel
Note: the network does not pass the link between the receiving card to replace the network cable.
