No video W5243 will not produce a video picture. The proven good monitor and cable simply say no signal and go black. Without vid I can't go any further in diagnostics. THe no vid condition just happened one day when the unit was powered up. Thanks

The DVI cable transports the display signal from the video card to the monitor.

I think what Ron is asking is if you used a different cable to connect the monitor to the computer. (I'm assuming you used an old 15 pin monitor cable or whatever those old cables were?)

Without getting into your BIOS:

So on your computer, you probably have an onboard video card (a video card built into the motherboard itself), and a dedicated video card (probably where you're seeing the DVI out).

It may be possible that you have the on board video card (with the traditional connection) disabled, when the dedicated video card is plugged in.

This isn't rocket science, so don't worry. Phillips head screwdriver is all you need.

Pull the side panel off your computer (assuming it's a tower... if not, it's the top panel). Once you have it off, you'll see that video card plugged into a slot on the motherboard, with 1 phillips head screw holding it in place (inside, near the back, where the DVI port is).

Pull the screw, and the video card should come out. From there, the BIOS should recognize your card is missing, and thus revert to using the onboard video card.

Connect the monitor to a different computer, to see if the monitor works at all.

Connect a different monitor to your computer, to see if your computer really is "sending" a video-signal through the "data" cable. If not, then either the data-cable or the video-card inside the computer is faulty.

Power off the monitor.
Unplug the video cable from the monitor.
Power on the monitor.
You should get some sort of display on the monitor saying "no signal" or something similar as you have already experienced - if so, good.
This means that your monitor should be OK.

Next, power off the monitor again.
Plugin the video cable back into the monitor, make sure you screw it in all the way.
Unplug the video cable from the back of your computer, inspect if for any damage.
Plug the video cable back into the computer, make sure you screw it in all the way.
Power the monitor on.

Any picture?
No? Make sure the computer is turned on and is not in any sleep or hibernation mode.

Still no picture?
Try the monitor with the same cable on another known working computer.

Still no picture (or you don't have another computer)?
Purchase a new video cable or swap video cables between monitors if you have another monitor.

Also make sure that the monitor cable is not crimped and it looks in good working order.

Make sure your monitor cable is secure on both sides. If you cannot secure it, see if you can straighten it and if a picture comes on.

If that does not produce a picture, can you connect the monitor to another machine? Does it produce a picture? If it does, we know that the problem is with the computer.

Can you put another monitor on the machine? If so, we have something with drivers/sync speeds. If not, we likely have a bad video card.

What connectors do you have at each end, ie output and input?
Is it S-Video at each end or are you converting, as I suspect, composite video out, yellow RCA plug, to S-Video in on monitor?
Converting composite to S-Video via a passive cable doesn't yield good results, as its simply feeding the composite to the two S-Video signal-components, Chroma and Luminance.
As the video output of a VCR has limited bandwidth, the signal out will never be perfectly clear, but if you can get hold of an active 'powered' booster / sharpener / crispener unit, it will help to clean up and amplify the signal, so improving clarity.
Another point:
A lot of generic Composite<>S-Video cables simply bridge or short out the C 'chroma' & Y 'luminance' pins.
A hack to improve the timing signals is to solder a 470pF ceramic capacitor across C and Y as shown in schematic.
This circuit show S-video input, but may work as out.

are you using the onboard? video... or a seperate vid card? if it was working and then suddenly quit? the onboard vid chip is out! cant replace that either try adding a seperate vid card and reboot

Hello!

I see many monitor with that trouble.
When you turn on comp., you can have a picture on monitor about 10-30 min. and that go in black screen, or If you change resolution again go in black screen.
You must repair monitor or bay another.

I had same problem. Try using another cable, VGA/Digital Video.
My problem was gone if I changed Digital Video to VGA analog.

The board that you may need.

there should be 3 sets of video rca jacks on tv or receiver they might have put them on the wrong rca jack in which they just need to be moved over
usually the 3rd set of rca jacks are component jacks not for tv or video but for low output signals say like cameras and only one set of rca's can be used at a time svg on one of them rca's will over power the vid's. so have no picture
