What if the monitor doesn't light up?

Generally divided into two cases, one is the problem of the monitor, one is the host problem.

Display:

Separate out, put on the power to see if there is a reaction (power key will be bright, whether the screen back to appear no signal or what word) if there is no signal pop-up screen, there is light, the power button will be bright, that is to say that your monitor is no problem. There is a problem with the monitor anyway.

Host:

1, the host to connect the power is normal, for example, hear the sound of the fan, power button will be bright, if there is the operating system and other hardware problems. No, it's a power supply problem.

2, the mainframe chassis open, the memory strip out, wipe the dust, and then put back, if there is no response, that is the operating system, or other hardware problems, this need to get a professional repair shop to deal with.

3, if the problem is operating system, you can try to install the system, you can also get the repair shop to let others help you deal with.
