    1. Your video card (or video output) on your computer is not working.
    2. The VGA cable from your computer to your monitor is faulty.
    3. The VGA cable is not plugged into the back of your computer.
    4. The computer is not turned on.

Your monitor is probably OK, it is the computer that probably has the issue.
On a great number of e-machines that I have worked on this is caused by the following:
1) Failed power supply unit. Swap with another of equal or greater power. Caused by failed capacitors in the power supply.
2) Failed capacitors on the motherboard. Look at all of the cylinder looking things on the mother board. If ANY of them have a bulged/raised top or are leaking fluids then you have bad caps( capacitors) and the motherboard is bad. Caps can be replaced by an experienced person. Caps should be perfectly flat. I have had several e-machines in the shop with this same problem.
3) Failed video card.
4) Failed processor.

What is most likely happening is that the computer is not passing the POST (Power-On-Self-Test) and therefore does not get to putting the video output to the monitor. When the monitor gets nothing from the computer it will display the message you are seeing. In a majority of e-machines that I have seen it is caused by bad caps on mobo and PSU.

If the machine is out of warranty then open the case and look at your motherboard (mobo), you may need a flashlight. If you could respond back and let us know if you have done this and if you have no bad caps, then what are you getting from the computer:
Fan turns on, CD lights briefly, Hard drive is spinning, etc. Also listen for beeps.

SOURCE: getting a no signal input

Several things xopunkyxox.

No Signal means there is no Video Signal coming from the computer. The monitor is working fine.

eMachines computers are budget computers. This means they sell for a low price, but also have low quality hardware components used inside the computer.

There are two top issues for computer failure. These really affect an eMachines computer.

1) Power Supply
The PSU (Power Supply Unit) used is a low quality unit to begin with, in an eMachines.

2) Dirty computer.
Dirt, dust, etc., can bring a computer down to it's knees.

The eMachines W3118 desktop computer uses an FIC K8MC51G motherboard.
(First International Computers, inc)

(The eMachines W3118 desktop computer is a North American model)

FIC K8MC51G Specifications:

http://support.gateway.com/s/MOTHERBD/FIC/105554/105554sp25.shtml

http://www.fic.com.tw/product/motherboard/AMD/K8MC51G.aspx

The eMachines W3118 motherboard has a Socket 754 processor socket.
Comes with an AMD Sempron 3100+ processor.
(1.8GHz)

AMD processors run HOT. Keep the Heatsink, and Fan on top of the processor, CLEAN.
The Thermal Compound (Thermal Paste or Thermal Grease) that is in-between the top of the Processor's case, and the bottom of the Heatsink, can dry out over time.
The heat developed by the Processor when operating does this.

A Power Supply (SMPS) has two cooling features.
1) The internal fan that you can see by looking at the back of the Power Supply, (Back of computer)
2) Heatsinks used inside the Power Supply.

Example of an internal view of an average SMPS,

http://en.wikipedia.org/wiki/Switched-mode_power_supply

Click on the photo to the top right. In-between the letters B and C, and also C and D, are aluminum Heatsinks.
What looks to be finned rectangles arranged in a vertical strip.

When the fan's blades, center hub, and surrounding cage, (Shroud) are clogged with 'gunk', the cooling capacity of the Fan drops tremendously.

Same thing with the fins of the Heatsinks.

[Construction of an average Heatsink is a plate of metal with tall, thin fins protruding from it.
The plate of metal absorbs heat from whatever object it is placed against, and the tall, thin fins absorb heat from the plate of metal.

The fins then radiate the heat away. With a fan used in conjunction with a Heatsink, the fan pushes air in-between the fins, and around the fins. The air flow helps carry heat away]

Heat = Wasted Energy
The overheated Power Supply strains to keep up with the call for power, but eventually fails.
(Hardware components inside the Power Supply fail)

I'm willing to bet it's Power Supply failure.
Test the three main voltages from the Power Supply. (3.3 Volts, {Orange}, 5 Volts {Red}, and 12 Volts, {Yellow)

The next thing to be an inherent problem with an eMachine desktop computer, are the Electrolytic Capacitors on the motherboard.
Low quality capacitors are used.
(Radial Aluminum Electrolytic Capacitor)

Visual identification of bad capacitors, (Electrolytic),

http://www.capacitorlab.com/visible-failures/index.htm

[NOTE*
Not all bad Electrolytic Capacitors show visual signs of failure. Sometimes the Electrolytic Paste inside the capacitor dries up. No bulging case, or leakage will be present ]

Summary:
1) Computer unplugged from power, Anti-Static Precautions observed, clean the inside of the computer out.
2) Replace the Power Supply.

Also remove the Ram Memory modules, ('Stick'), and clean the gold plated contact pins on the ram memory module, with a pencil eraser.

http://en.wikipedia.org/wiki/File:Generic_DDR_Memory_%28Xytram%29.jpg

(You can click on the photo to enlarge)

Your eMachines W3110 uses DDR Sdram ram memory.
184 contact pins. 92 on Each side.

[It is DDR Sdram that operates at either 333MegaHertz {333MHz}, or 400MegaHertz. {400MHz}. Also know as PC2700 or PC3200, respectively]

Handle the ram memory by the body. Refrain from touching the contact pins.
The body of the ram memory is coated with a see-through protective plastic, which shields it from Static.

The pencil eraser is rubbed going Down the contact pin. Start at the top, and go down. If you are using the eraser on the end of a pencil, and not a solid eraser, refrain from letting the metal band touch the contact pins.

After you have cleaned each contact pin it may look as though you have not done very much.
I assure you have. Doesn't take much 'corrosion' on a gold plated surface.

Use air to remove the eraser dust before reinstalling the ram memory.
You can use a can of compressed air for computers, or air pressure from your mouth will be sufficient.

Use compressed air to clean out the ram memory slot/s on the motherboard also.

For additional questions please post in a Comment.

Im trying to install a new video card on an emachine and i keep getting a no signal input on the monitor. thats what i started with.


Is the new video card compatible with your motherboard?If it is , can you try connecting your monitor VGA Cable from your video card properly?

And also if you are using a PCI Video Card you should try to install it to another slot if theres an instance that a PCI Slot doesnt work.

When I turn on my emachine, it reads:


It means your video card is not out putting to your monitor. If it clears up, it is normal. If it continues, check your video card and/or settings.

No input signal form a laptop to a projector


Hi jkoceng,

What type of interface cable are you using to connect to the projector? 15-pin VGA? S-video?

Generally on laptops if you look at the keyboard on the function keys (F1, F2, etc.) you'll see little icons such as adjustment of volume, brightness, etc. Look for one that looks like a monitor or screen. Usually this is on the F5 or F6 key. If the icon is blue, look for the corresponding key on the keyboard (Fn key, CTRL, Alt, etc.) and then hold that when connected to the projector while you press the appropriate function key. This should alleviate your problem.

Of course, you'll also want to be certain that you're using the correct input function on the projector.
