My emx-mcp61p-avl has power but no display no beep. video card is new and compatible with my motherboard. RAM is new also.


Just because the ram and video card is new does not mean they work. But since you say it has power, I'm assuming it boots up all the way except the screen is not displaying.

If this is a laptop try the steps below.

Shine a flashlight on the dark screen to see if you barely see the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.



If it is a desktop try the steps below.



Try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor shows the display, then your original monitor is bad. If the Borrowed monitor does and same as your original monitor and does not show a display then your video card has an issue.

Reasons of y signals not going to the monitor


Is the monitor showing a blank screen or is it showing the message NO SIGNAL??

If you have a Desktop try the steps below:
If it is showing the message NO SIGNAL, then the video card in the computer is bad, because when the monitor is bad, it will show nothing at all. To isolate the problem plug another monitor on the computer and see if it displays. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok, then your original Monitor is bad. If the Borrowed monitor displays the same as your original, then the video card in the computer is bad.

If it is a laptop try the steps below:

If it seems like it booted up, you hear fans running, hard drive spinning, lights, (except the display is black) then try the steps below.

Install a new graphics card and plug your monitor into that new video card. Do u get video output? If not, the problem is the system board.If u do, the problem was the graphics card.

When I hit power button on computer, power light doesn't come on...and the fan kicks on, but nothing else happens. nothing shows up on monitor except the test screen with 3 colors...the computer doesn't...


THis sounds like a power supply issue.. I had a similar issue with mine. my fan would kick on for about 2 seconds then shut off.
Hope that helps
