Its probably the power supply..they tend to go quick on emachines.!Replace the Power supply.

Did you forget to connect the 4 pin power plug to the display card or motherboard??????????

Everyone would,lol. Emachine doesn't like to give out info or may be that's why they're so cheap. Basically you throw them away when the board goes out.

Unfortunately eMachine manuals are not very thorough. Here is a link to the support page for your computer:

w2060 Support

At the bottom of the page is a support telephone number. Call and explain that you need the front panel pinout for your computer. That's what it sounds like you have disconnected. There is also a link for online chat if that is an option.

I did find this page eMachine Pinouts that may be of help to you. It does not give the colors of the wires, but look for the abbreviations on the connectors such as HDD, PWR, and PWR LED.

It sounds more like the computer isn't starting up. The "no signal" message is coming from the monitor itself to tell you it's on but there's nothing coming in to display. Normally no special drivers are required for the monitor, and you'd see at least the computer maker's splash screen and BIOS messages if the computer was starting up properly.

You'll need to determine what is keeping the computer from starting up. Make sure it's getting AC power and that the power light comes on when you press the front panel power button. You may need a power supply. If the computer comes on but doesn't boot you may have memory problems or trouble with the motherboard. But your monitor is working properly.

You can fix that by getting a new graphics card
I'm assuming you have a T3830 emachine.
here's the link to replace video card

Possible reasons are bad power switch, bad power supply, bad motherboard, bad memory , device card is not seated properly. Suggest replace power cord to see if still no power, also you may want to remove cover and make sure all your memory and device cards are seated corrrectly. If you get a amber light at the power button, bad motherboard is likely cause
