You should try your PC with another monitor to make sure it is not the video card problem.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

No Signal.
No signal coming from the computer.
The monitor is working, but there isn't any video signal coming from the computer.

1.Could be a bad video cable. The one from the monitor to the computer.
Do you have another computer available to test this monitor on? Use the video cable attached to it now.

Works?
You have a computer problem.

Doesn't work?
Use the video cable on the computer you're doing a test with.

Works?
You have a bad video cable.

Computer problem.

Does your computer have a graphics card, or is it Integrated Graphics that the monitor is plugged into?
(Integrated Graphics is also referred to as 'Onboard' graphics. ON the motherBoard)

With Integrated Graphics your monitor will be plugged into the I/O area on the back of the computer.
I/O = Input/Output

This area, is where the rectangular metal shield on the back of the computer is located. A mouse and keyboard are usually connected in this area.
Example of an I/O Shield,

http://ep.yimg.com/ca/I/directron_2079_111707086

A graphics card is a separate hardware component that is plugged into an expansion slot, and you will see it towards the bottom of the computer case. There are slots in the metal frame of the computer case, and you will see the outside edge of the graphics card located in one of these slots.

Example of a basic graphics card,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5271084&Sku=G458-9603

It could be a problem with the Integrated Graphics, (GPU soldered to motherboard), or an issue with the graphics card, if used.

The main problem I see when repairing are one of three issues, or a combination of two or more issues.
1.The inside of the computer is dirty, and the power supply.
2.The power supply is bad.
3.Electrolytic Capacitors have failed, or are failing on the motherboard.

1a.If the inside of the computer is dirty, so is the inside of the power supply. The power supply's fan draws air through the computer.

Dust/Dirt/Hair, and other foreign objects, are drawn in with the air from the cooling fan/s, and the power supply fan.
No matter how good a person is as a housekeeper, this foreign material is drawn in. It requires a regular cleaning of the inside of the computer, as well as the power supply.

The computer is turned off, and unplugged from power. Computer case open. A can of compressed air is then used to clean the computer. (Plastic straw attached. Do Not make the small processor fan spin too fast. It is only designed to spin so fast. Spinning it faster than it is designed for, can lead to premature failure of the fan's bearings)

2a.Power supply failure. This is a multifaceted problem.
When foreign material clogs the cooling components inside the computer, (Fan/s, and processor heatsink), plus the power supply, (Fan, and heatsinks inside), the power supply has to put out more power.

Heat = Wasted Energy.
The more heat due to cooling capacity drop, the more power is required. The power supply can only keep up so long, and components inside eventually fail.

Generally it's Electrolytic Capacitors as they are the weakest link. Electrolytic paste inside the capacitor develops a gas, and breaks the seal stature of the capacitor. This leads to Electrolytic paste oozing out, and capacitor failure to follow.

A power supply with failing, or failed capacitors has a weak voltage rail, or more than one voltage rail.
There are three voltages produced by a personal computer power supply.
A.3.3 Volts
B.5 Volts
C.12 Volts

With a bad power rail the power supply has enough power to light lights, and spin fans, (Usually), but not enough power to turn the processor on.
1.ALL the lights require less than 1 Watt.
2.EACH fan requires 2 to 3 Watts.
3.A typical processor requires 55 to 125 Watts. Depends on what processor it is.

(You may even hear the harddrive spinning. Enough power to make the harddrive motor turn, but with no processor, there is nothing to make the Operating System on the harddrive work. Operating System example: Windows XP)

3a.Bad Electrolytic Capacitors on the motherboard.

As mentioned, Electrolytic Capacitors have Electrolytic paste inside. The paste develops a gas, (Hydrogen Gas), and pushes against a rubber seal on the bottom of the capacitor. It can also push against the top of the capacitor, and break the capacitor metal case open.

(Usually there is an X or lK on top of the capacitor. This shape is stamped into the thin metal on top. It spreads open when there is too much pressure, alleviating the pressure that has built up. Paste oozes out of here also)

Electrolytic Capacitors that surround the Processor are Voltage Regulators. The Processor must have a clean, steady, supply of voltage. The Processor has a very small tolerance range.
Too little it doesn't turn on. Too much, and it won't stay on.

This details out the visual signs of Electrolytic Capacitor failure,

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

Electrolytic Capacitors do not always show visible signs of failure. The paste can dry up inside, and no external failure is present.

If you see capacitor failure on the motherboard, then you automatically know what is wrong.
If you do not see failure of capacitors, then you may want to try using a known, good, power supply for a test.

Would appreciate 'hearing' what the outcome is.

Everytime i start up computer a sigal appears saying "no video input"


I'm assuming after a few minutes, it does get a signal from your computer and all works? It does take about 30s +/- 90s for a computer to generate an output video signal so if your monitor comes on first, before the computer can send a video signal, then you'll see that message. You should see the same message if you shut down your PC and leave the monitor on.

Screen will not stay on, getting message no input signal


The message input signal means no signal is being feed to the monitor.
Check the cable use to connect the monitor to the video card.. fix and secure the connection.
If the computer is reading and you know its working, check the video card.
Turn off the CPU disconnect the video card from the motherboard and reconnect.
Try to open your CPU and see if it reacts with your monitor. If nothing happens replace your video card

  2. change the video cable
  3. do a monitor selftest
  • turn off the monitor
  • disconnect it from the power outlet
  • disconnect it from the computer
  • turn on the monitor without the video cable
if you see the monitor information (a box with RGB white colors, the monitor is working)

  • problem might be the cable, video input port of the monitor or the video output port of the computer

My samsung 940N acts like a florescent tube, tries to start and doesn't


Use the self test feature.. follow the steps..

1. Turn off both your computer and the monitor.
2. Unplug the video cable from the back of the computer.
3. Turn on the monitor.
If the monitor is functioning properly, you will see a box in the illustration below.
This box appears during normal operation if the video cable becomes disconnected or
damaged.
4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the
monitor.
If your monitor screen remains blank after using the previous procedure, check your video
controller and computer system; your monitor is functioning properly.

Warning

The Power supply inside the monitor can be hazardous and donot open the monitor while power on.

Donot work with the monitor when it is open and the power supply is on.

If there is something wrong with the input signal, a message appears on the screen or the
screen goes blank although the power indicator LED is still on. The message may indicate
that the monitor is out of scan range or that you need to check the signal cable.

WhenI turn my monitor on, a screen appears saying VGA input - no signal & DVI input - no siganl & then it goes to sleep


Do you have multiple Video cards installed in your computer?

Check the monitor on another computer to verify the Monitor works and so does the cable.

If Monitor works, cable works, and you have 1 video output from your computer, then your Video card is probably no good.

Dell m992 crt monitor


If it's getting no signal, make sure the monitor is set for the correct input. This would be either analog (if your cord has blue ends) or digital (if the connectors are white). Depending on wt yhat your monitor is, a button on the monitor will help you set that. If it's set for the correct input signal, then switch out a different cable to see if perchance you have a bad cable out of the box. If there is another PC or laptop setting around, plug your monitor into that to make sure it's good and maybe even plug THAT monitor into yours to make sure there is nothing wrong with your video card. Let me know what transpires. If this takes care of things, please help me out by rating it accordingly.
