The LCD display can turn on the power switch after a few seconds the computer screen display lights turn off the power after a few seconds to open and bright and close... Is not bad. The power adapter.... do not know how hastily to and thank you heroes!!I got a power adapter from the company and changed it. No, I didn't expect the adapter to be broken. 12V 4.16A
The monitor power switch may leak, or when you turn off, let the touch switch contact two times, the monitor is opened again!When the next shutdown, pay attention to observe, is not the monitor really automatically opened, and if so, the switch may exist leakage, change a just fine
According to my maintenance of liquid crystal, there are several situations: 1, generally high voltage protection, not very serious kind of high voltage protection, you can manage the chip through the protection of the foot grounding. 2, the power on the board of a capacitor explosive pulp or drum bag phenomenon, replaced on the OK. The bad performance of the 3, one of the high voltage coil power supply board, now the general case is directly to the general high pressure, the poor performance of the lamp light a few seconds can be the perfect solution, because the general pressure did not set up the general protection. 4, if a few seconds feel bright screen than the normal use of dark words, there may be a bad performance caused by the bright lamp seconds phenomenon, direct replacement of lamp can be solved, or the third point is that the change of general pressure can be solved. These are generally more familiar with the point, the circuit principle can go to get, otherwise there is an electric shock risk, because the power on the board is energized with high-voltage, without electricity, the case is without high pressure. General take outside repair one hundred yuan less than normal, ha ha, hope to say these can help you.
The high voltage board for LCD is faulty. Don't try again. Please repair it as soon as possible.
