My monitor goes black when it is connected to AC Adaptor.

Is the screen black from the moment you turn your PC on? Or do you see the BIOS splash screen and Windows loading, but when Windows starts it goes black?

The lamp on the power supply adapter should be on the minute it is plugged onto the AC outlet without the DC plug connected to the monitor, if it is not on then the AC adapter is bad, you can check the DC voltage with a digital meter. Post back so we can guide you further.

please check the resolution setting of your windows
if u canot go to windows please try to enter through safe mode
and go to device manager and go to display and right click on the adaptor and uninstall it and resart the windows it should be fine

• 1) TAKE OUT YOUR LAPTOP BATTERY
• 2) REMOVE YOUR AC ADAPTOR CORD, that's the wall power, remove it.
• 3) NOW HOLD DOWN THE POWER BUTTON FOR 30 SECONDS.

That will drain any static electricity that has built up on your laptop system board and many times fixes the problem of a black screen. After the 30 seconds re-connect your laptop to the wall power and hit the power button normally and see if the laptop comes back up.

Replace your battery.
Restart!

The monitor will have a label on it stating the input voltage and the socket config. The adaptor will have the output voltage etc. As long as the 2 match then no problem

if your monitor came with a disk try installing the drivers again you might still have the drivers for the previous monitor you had with your system if not try going to the manufacturers website and getting the drivers and install them

CANNOT COMPUTE!!!! NEED MORE DATA! Is your monitor the problem or the computer? Try connecting the monitor to another computer. You can also try connecting a laptop with an external video adaptor to the monitor to test it.

Traggio,

It's seemd you need a new AC Adapter. You can get a new Universal AC Adapter for your LCD monitor. Check out this website @ www.3rd-rocks.com

You will need to check the power adaptor for voltage , if that checks out then you will have to check the power circut in the monitor, look at the protection component and diodes in the power circut

Same problem here. Does anybody have an answer?
