1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.

Try a different power cable. If it uses a 'brick' type power supply, try a different one. If that doe not fix it, the monitor is bad (which is why it was given to you). Monitors are cheap, get a new one. Good Luck.

Hello,

It is the picture picture board on your monitor that is malfunctioning, since the power led or button is on, but blue shaded screen, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

Have you tried reseating the cables? if not try it first, then if it doesn't work you'll notice that after you unplug the cable that's connecting the lcd from where it's plugged in , (make sure the lcd is on) if you see the colors that means the lcd is working properly if not then there is something wrong with the monitor, but if the colors came up the lcd is working fine,. Try to check where you plug it in.

Sir,
You are suggested to check if you serial cable is in fine condition and it properly pluged into the Monitor and VGA. and do also try changing the serial cable .

try to replace the cables first. if it that doesnt help then replace the monitor.
