When the power supply of the led screen is insufficient, when the display is close to white (high power consumption), it will cause the screen to flicker. According to the power demand of the cabinet, prepare a suitable power supply. Step 4: Check whether the green light of the sending card flickers regularly. If it does not flicker, restart it. Check whether the green light flickers regularly before entering win98/2k/xp. If it flickers, go to the second step. Please check whether the DVI cable is connected properly. If the problem is not resolved because one of the sending card, graphics card and DV cable I is faulty, please replace it separately and repeat step 3. Step 5: Please follow the software instructions to set or reinstall and then set again, until the green light of the sending card flashes, otherwise repeat step 3.
