This may round ridiculous but we cant find where the power plug connects into the monitor ????

AC Adapter For eMachines E15T3r 568 LCD Monitor Charger Power Supply...
As you can see from the picture the power plug is a small round connector similar to an audio input. Power Connectors
look for a connector like the DC socket in the picture

THe round black one is for a power supply really big block one that need to be plugged in. Is your power light next to the volume button on.

If your monitor has built-in speakers, then you can connect the audio
output (stereo mini plug) from your computer to the monitor. Look
at the back of your PC, there is a light green Jack: that is the Audio
Output Jack (Consult your PC user's manual for verification)
Here is what your cable should look like:

If the 'plug' is round, the keyboard needs to be plugged into the round PS/2 port that is purple. Then reboot your computer. PS/2 devices were not intended to be plugged in when the power is on, thus the reboot or power off, power on. USB devices can be plugged in while the power is on, but may take a minute or two while your operating system loads the appropriate drivers for your device. -DellTech1

It sounds like the backlight circuits are not working, it can be due to bad power supply.
Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

probably your power supply. Is it a cord direct from plug in for is there a box between where you plug it in and then a small round end that goes into the monitor. This would be the good news. If it plugs in direct then that means the power sopply is in the monitor itself which means more expensive to fix

Hi,
It is powered with a 12v DC adapter:


The small round hole with the pin in the middle..

Hope this helps

Happy New Year!

The two vx900 s I have here have more of a rectangular plug for the power. Inside it is three large prongs and on the backside should be 3 wires. Two of which go to a smaller plug that connects to the power board.
The power cord is the same as found in many desktop computers.
If this is what you are referring to. Then the plug should be connected inside and it snaps into place onto the meatl part inside the monitor.
You may have to disassemble the unit to get it back together.
Sorry for delay in reply, I never was notified that you had replied.

For your monitor with built in speakers, there should be a cable usually the plug is green in color, coming from the monitor which needs to be plugged to the back of the computer for the speakers to work. If you don't see a cable, then there is a plug on the monitor where a cable would go.

Yes you can connect external speakers. They plug into the back of the computer. There are usually round ports on the back colored blue, pink, and green. Figure: http://www.ultimatepcrepair.com/files/bsound.jpg (sometimes there is more, depending on your computer) The speaker cable plugs into the Green color one.

If you need more help just comment.

This is a very difficult question to answer without knowing more info, but here goes:

Check the power cable, there should be only place to plug it into. This may be one of several styles depending on your model, usually a 3 prong female (just like your PC's power cable) connector, or a single pin female connector (looks male but has a hole in the center) will connect to the back of the monitor.

If you get power, but no image: VGA connections will use a large blue connector with 15 round pins, 3 rows of 5. DVI will be a large white connector with slotted pins, with varying amounts of pins depending on the type of cable (analog, digital, or both). HDMI will be a small connector that resembles a large USB connector. You may also be using a composite or component cable, which will be color coded to the ports on the monitor.

All styles of connectors will physically only connect to the corresponding port. Check all connections and make sure they are all secure and connected to the correct locations on the monitor. Doing this should resolve your issue.
