SOURCE: Acer AL1916W 19" problem

Hello mat78, Unfortunatelly the problem is hardware based. You will need to have the monitor repaired in a service center. Here's why: LCD/TFT monitors don't produce light themselves. They are composed by a matrix of transistors (TFT - thin film transistor) that have the property to reflect or allow some light (certain wavelenghts)to pass through them. They don't produce light by themselves. Instead there is a fluorescent tube (neon like) light inside the monitor and that's the light source used in order for you to see what's on the screen. A flourescent light is suposed to last pretty much, i don't think yours has a problem, you say it works for some seconds or so. Instead your problem is most probable with the inverter circuitry that powers on that light. It's a common problem among these types of monitors but in your situation i don't think it will be an expensive repair. In the case that the screen is dark (in a dark place you can't read or view anything on it) but if you apply light to it ( a flashlight or something) and you see something, then the problem is most likely to have occured with the invertor. Try to ask at a local service center for a repair, this shouldn't be an expensive procedure. Hope this helps.

SOURCE: kds model 780 monitor no signal, power button does not work

My monitor does the same thing at times and sometimes shows "No Signal" and at other times the screen will maintain the images but the backgound color switches to mustard yellow. In each of these cases I have been able to solve the problem by unplugging the power cord from the electical outlet for about three seconds and plugging it back in. I have a KDS model 780 LCD.
GOOD LUCK

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 have a acer.x223w when,it powers up the.screem stays black, n i get a blue blinking light on.the bottom


I disagree with ikkenom only due to the symptom of the flashing blue light. This would indicate to me that the monitor is not getting any display signal and is in sleep mode at least the is what happens on my Samsung monitor. Used to be that they use a two color led in the monitor, green when ON and getting display signal and amber or orange when in sleep mode. I would check the computer by trying a different monitor. If you have a second monitor, great, if not, maybe a friend will let you bring your computer over and try the computer with their monitor. Could also be a display adapter setting. Do you get any change when you first turn on your computer? i.e. Do you get the BIOS or manufacturer screen when first turned on? Also if you disconnect the monitor cable from the computer and power cycle the monitor, do you get a No Signal display for a few seconds before the monitor goes black and the blue light starts flashing?

Let me know what happens with the testing above or if you need further instructions to carry out testing.

Thanks, Jim

No Signal After Restoring PC to Factory Settings


It's not recognizing the TV as a monitor. Find out what resolution the TV runs, then set the PC to those using the other monitor.

CPU ON WITH NO SIGNAL TO MONITOR


Make sure your monitor has power and that the VGA cord or USB cord is properly connected. If your monitor has power (power light is on), disconnect the VGA or USB cord from it, but leave the power on. This will tell you if the monitor is working as it shold display a message like self check or no signal detected and then proceed to display a screen saver. If not then I'd suspect your monitor. If the monitor is ok, then try a different cable between your computer and the monitor. If that fails, then your video card may be defective.

Compaq WF1907 19" monitor backlights are on, but


Check the monitor on another computer to verify if using correct setting for this monitor will allow a clear image to be displayed.

In windows 7, the monitor should be detected and installed automatically.

What version of windows are you using?

Monitor: Compaq TFT5015 Displays vertical lines


Check that the signal cable from the computer is firmly connected and that there are no bent pins in either end. If the trouble continues, the problem is in the monitor itself. Given the low replacement cost, it's uneconomical to try repairing these.

Problem with the monitor


Hi,

The three boxes represent the built-in diagnostics of the monitor. The letters G is green, B is blue and R is for red, the 3 color guns of the picture tube of your monitor. The words "Self Test" indicates that it is in diagnostic mode since it has powered up, it is also then expecting a video signal from a source to be coming in; the display "Check Your PC And Signal Cable" indicates that it is not receiving any video signal from the source which is your PC or more specifically the PC's video card; and the display "Monitor Working" indicates that the diagnostic has determined that nothing is wrong with itself and therefore it has got to be your PC that is in question. The intermittent appearance of the boxes is when the diagnostics restarts itself and eventually finds the same problem.

To determine if it is the PC or the monitor, use another PC (even a laptop with matching VGA output) and try it with your Compaq monitor, see it it will work or alternately, try a different monitor to connect to your PC. The outcome will determine which is at fault.

If you have determined/verified that it is indeed the PC, you should focus on the video/graphics card. In some PC models/versions, the graphics/video is built-in to the motherboard and you should check the memory since this is shared. The only way is to replace either.

Hope that this be of some help/idea. Pls post back how things worked out or should you need additional information.

Good luck and kind regards.
