Take your phone and plug it into a different working jack in the wall. If you get the display then you have a wiring issue and you will have to call a tech to repair. If display is not working you will need to buy a new phone. You can buy one at www.ivdsonline.com

L no display


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.

For a laptop:

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.



For a Desktop:



Try using another monitor on 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 not show on the display then you Video Card is bad.

On but no display


So the power is on but there is no display. Does it look like the laptop booted all the way? Does it look like the laptop is running but there is no display?

If the laptop is running, you hear the fans running, the hard drive running, etc. but the display is black, 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 beany 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.

The lg fratron ez. H713sh is flashing a green led and nothing is coming on e display, thought of connectng otha monitors bt didnt succeed.


If you get the same result with the other monitors, you may have to replace your VGA card.
First turn off the system.
Remove the VGA card from your computer.
Clean it and fix it again. This might fix the problem.
If you get the same result, replace your VGA card.

No display on Monitor. Its goes Black Right from the start.


If your computer boots correctly and there is no beeping or warning tones coming from it and you have tried several monitors I would say that your video card has died

if your computer supports it you can obtain a new one at your local best buy, walmart ect or you can order one very cheap at the following links

you may have a geeky neighbor or computer nerd like me have a quick look at it so you can see what slots are available and see what card your PC will support

link 1

link2

I have used both these places many many times and found them to be very reputable

I hope this helps good luck

Over Range


The display card resolution is set too high for the handling of the monitor, or the system board in the monitor is faulty.
