The BenQ LCD screen flashes for a few seconds and then returns to normal, what s going on

The screen is splashing. Go to the pits and check it out.

Now the monitor is not expensive, let's change it, it's better than repairing.

My monitor also has this problem, but it has been returned to the factory for repair, and the manufacturer replied that the display switch is in poor contact.

Mr. Yue: Hello.

Can you tell me exactly which three little transistors and one resistive loss.

There are many reasons for the flickering of the monitor screen, among which it is caused by the failure of the monitor and graphics card, and the user can troubleshoot and solve it by following the steps below:

1) Check whether the graphics card driver is abnormal.

Try reinstalling or updating the graphics card driver to see if the monitor is still faulty 2) Check if the monitor is abnormal.

Press the button on the monitor (OSD menu), find the factory reset item, and click to take effect to confirm whether the fault exists. Confirm whether the contact of the monitor cable is intact, confirm that the cable is firmly connected, whether the cable is damaged, and replace the cable to confirm whether the monitor fault persists.

3) Check if the graphics card is abnormal.

After shutting down, try changing to another graphics card and rebooting it. If the fault disappears after the replacement, it proves that it is a problem with the graphics card hardware, and the graphics card needs to be repaired.

When it is not lit, pay attention to observe whether there is a faint image from all angles, if there is, it should be a problem with the backlight plate, just disassemble the monitor and replace the lamp.

There may be a problem with the screen.,,If it's troublesome.,Basically, there's no point in repairing.。。

The cable on the power strip is virtually connected.

What color is the indicator of the monitor when the screen is black? Green, yellow, off, flashing?

When you resume after a second or two, does the bezel flicker before the display lights up?

Is the computer working fine after restoring? Are there any signs before the black screen, and if so, what are the signs?

If it is a power supply problem with the monitor, there are two possibilities, 1, the power is off, the indicator light is off, and the front bezel of the monitor lights up when it is restored after a second or two. After the display is completely powered off, the crystal screen is not fully working when the backlight tube is lit at the time of the second power-on, so the bezel will flash.

2. The voltage is unstable or surged, the self-protection is extinguished, the indicator flashes green, and the front bezel flashes when the display lights up when it recovers after one or two seconds.

Display quality issues.

1.The lamp was damaged, and when it was restored after a second or two, there was no bezel flickering before the display lit up. The indicator light is green.

2.Other parts may be damaged, or the phenomenon may be different, which is unlikely.

Problems with graphics card or monitor cables, 1The indicator light turns from green to yellow, the display line is loose or the graphics card is hard faulty, 2Slow running before a black screen, a soft glitch on the graphics card, a driver issue, or a problem installing a game.
