What is the phenomenon that the capacitance on the LCD monitor is broken?

After the leakage of the capacitor drum on the internal power supply board of the LCD monitor, the power supply load capacity is poor and the power supply is insufficient.
Showing the phenomenon
1. Use a black screen for a while after the monitor is turned on.
2, the monitor boot screen screen flashes off, black screen.
Since there are many high voltages involved in the display, it is easy to cause electric shock accidents or enlarge the fault surface due to operation errors without repairing the circuit. Therefore, it is recommended to send a professional repair point to replace the damaged capacitor.
