Start with the basics, so check the fuse in the plug, change wall sockets and if this doesn't help unplug the monitor and hold down the monitor's power button for 30 seconds (time it, it'll seem to take forever).
If non of this helps post back telling us if the power LED comes on, if the monitor comes on but gives you an error message and if pressing the menu button brings anything up on screen.
BTW Emachines T6420 is a model of desktop computer not a monitor, even if the monitor was supplied with the PC. The make/model should be marked on the label on the back of the monitor and would help us in helping you.

Lets start with the basics. Does the monitor have power, do you get a light on the monitor when you try to turn it on? If you do then do you get any lights on the computer when you try to turn it on? If the monitor has no lights on it check the power connections and if still no lights then try plugging it into a different outlet preferably directly into the wall. If still nothing then the monitor is bad. If the computer has no lights but the monitor does once again try plugging it in to a different outlet and if that does not work there is a problem with the computer most likely the power supply, CPU, or motherboard. If both have lights but you get no display on the monitor then check the connection between the monitor and the computer. if the connection is good (I would ***** in the screws on the sides of the connectors just to make sure there is a good connection) then there could be a problem with your video card.

The monitor will not get a connection. I need to know where the video card is located.


This is eMachines Support, T6420 desktop computer>Specifications, and downloads page for the User Guides,

http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=T%20Series&model=T6420

The eMachines T6420 does not come with a graphics card from the factory.
It comes with Integrated Graphics.

Integrated Graphics is also known as OnBoard Graphics.
On the motherBoard

The GPU is soldered to the motherboard.
(Graphics Processing Unit,

http://en.wikipedia.org/wiki/GPU

OR,
someone has installed a graphics card, into the PCI Express x16 slot on the motherboard.

You can determine real easily if your computer is using Integrated Graphics, or a graphics card.

If it is using Integrated Graphics, the monitor will be plugged into the I/O area, on the back of the computer, and into a VGA port,

http://en.wikipedia.org/wiki/VGA_connector

(I/O area;

I/O = Input/Output

The I/O area, is the area that has the rectangular metal shield, and Input/Output devices are plugged into this area.

Devices such as a Keyboard, Mouse, Printer, and so on )

HOWEVER, with the motherboard used in an eMachines T6420, the I/O area could also have a white DVI port.

http://en.wikipedia.org/wiki/Digital_Visual_Interface

This was an option offered. The DVI port still connects to the Integrated Graphics on the motherboard.

The eMachines T6420 uses an MSI MS-7207 motherboard.
(Micro Star International, Inc.)

http://www.tigerdirect.com/applications/searchtools/item-detailsInactive.asp?EdpNo=2665522

The above link is to,
1) Show the motherboard
2) Provides a link to the Motherboard Manual

Looking at the photo of the motherboard, you will see two long White slots.
Above these two slots you will see a longer White slot.

The bottom two white slots are PCI expansion slots.
The top longer slot is a PCI Express x16, expansion slot.

This is where a PCI Express graphics card would go.

I would like you to scroll to the bottom of the page, to the Product Resources heading.

Under it is a link to the Motherboard Manual, for the MSI MS-7207 motherboard.
Also known as K8NGM2-L

Left-click on the blue - MSI K8NGM2 Series Manual.

You will be looking at a blank white page, as the PDF file downloads in the background.
Took 34 seconds with a medium speed DSL connection, for me to download it.

NOW,
No Signal on the monitor, means the monitor is Not receiving a video signal.

1) Check the monitor cable if it is removable. Use it on another working computer to insure it is good.

2) If the monitor cable proves to be good, the next area to check would be the graphics.

If the computer is using Integrated Graphics, and no one has installed a graphics card, the test would be to install a graphics card, and plug the monitor into it.

Computer off, unplugged from power, Anti-Static precautions are observed before reaching inside the computer, and handling the graphics card.

I don't think the problem is the graphics. Could be wrong, but we'll see.
Let's carry the diagnosis past the graphics for now.

I think the problem could be due to a bad Power Supply.
Weak Voltage power rail.

Enough power to light lights, and spin fans (Perhaps), but not enough to turn the Processor on.
(Fans may be spinning, or may just spin a few times, and stop)

1) ALL the lights use Less than 1 Watt of power
2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use 51 to 125 Watts of power.

Continued in an additional Comment.

Change the order so that the CD boots first. Try to run Repair from the Windows CD. If unsuccessful, you'll need to reinstall Windows.

No you cant, the gateway GX7018E uses integrated graphics like the T6420. You will have to buy a cheap PCI or PCI-E graphics card to test it out.

Hi, i am workiing on an emachine T6420 for my brother and this thing starts up with the fans running and a black screen. my monitor that i connected to his computer shows a yellow standby light on the...


That's exactly what it sounds like. I would put in a new video card (or used one, if you have one) into one of the expansion slots and run it from there.

I would suggest to go into VGA mode just to make sure, but since your monitor never even gets off standby, I'd be 99% it's the onboard video.

Hope this helps!
