Hello, my computer LCD is bright and black. The power light is bright and black. What's the problem?

Answer:

Power lines and data lines no problem, it may be graphics card driver problems, update the driver to tryNo, just change the data line. It turns out to be VGA. Try it for DVINot yet. Maybe the monitor is broken

It's better to change a power line. Be careful of the short circuit.

Monitor power failure. Judging from the phenomenon, should be 300V or 12V filter capacitor drum, the capacity decreased, resulting in insufficient power output power. The process is: when the monitor starts, the power supply is insufficient, the backlight is extinguished, and after the backlight is extinguished, the voltage is restored to normal, and then re lighted.
