What to do if the LCD fails

Shenzhen Sanyuanjing Science and Technology Co., Ltd. will share the following troubleshooting methods for LCD screens!

1, the LCD flashes
Now that the display has bid farewell to the era of CRT, it has entered the era of liquid crystals. The characteristics of liquid crystal displays are no flicker and no radiation. However, sometimes the display surface will also appear flickering problems, and sometimes the face painting is also shaken badly. In general, there are two kinds of reasons. One is a soft fault, and the user can eliminate it. The second is a real hardware failure. You need to send the monitor to a service station.
2, poor display card VGA signal output
At present, many video card VGA parts are simplified and severe, and can only adapt to CRT monitors. After encountering the liquid crystal display, the original appearance is exposed, especially the integrated display card. The solution is to replace the display card. If the monitor card has DVI-I, use the adapter to use the DVI connector.

4, key failure
Measure the voltage of each button to the ground. If the voltage is too low or 0, check whether there is any short-circuit in the circuit between the button board and the CPU, whether the circuit breaker is open, whether the pull-up resistor has any wrong value, and whether there is any wrong value in the connection. , pay attention to whether the key itself is damaged.
