A thin line of liquid crystal display screen
You can turn on the monitor, unplug a 30 foot screen from the rear of the screen, clean it, reinstall it, and test the machine. If you can solve the problem, it means the poor contact between the screen and the thread. If that's still the case, the death penalty for the display can basically be declared. The reason is that if the small vertical line is fixed is the most bad LCD cable. If not the majority of small vertical lines in cold condition is caused by the fault screen circuit. Screen line and circuit maintenance feasibility is not high, even if some places can maintain costs, but also can buy a similar type of good second-hand display.
Can be judged asVideo card problemPlease change the video card to another computerIf you remove the graphics card problemPlease take the monitor to the electrical appliance shop for maintenance
Obviously is the LCD screen drive, the wiring has bad contact. But this cable doesn't work well, so it needs special tools. Repair.
