When the monitor is not connected to a source then it displays that there is no connection like a normal situation. When i connect a pc the picture goes black and the backlite turns off. With another monitor it works fine.
Powersupply seems to work alright.
Please can you help

Re: Screen goes black and no backlite when connected
Please reduce the resolution/ Frequency of your Display Card in system and see whether you can see some thing. Else connect this monitor to another system with low resolution. Let me know your feedback.

Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.
I suggest you connect the VGA cable from the computer to another monitor or a laptop, just to make sure that your monitor's back light is faulty. If it does show on the other monitor or laptop, then the back light is really faulty. And i suggest that you get a computer technician to open it up for you if you can not do it yourself. Or you can get a sharp-flat object and open the monitor starting from the bottom of the monitor working your way round to the top. You will notice finger-like structures that hold down the monitor covers together. Make sure you do not break any of those. When you open it, check on the circuit board where you connect the power cable. Check for any bulged or leaking capacitors. Capacitors have a job to hold down the power from the source long enough for your display. For faulty capacitors, the monitor will either remain black with the orange light blinking, or it will display for at least between 2 to 8 seconds and then goes black. Buy the same type of capacitors and replace the damaged ones. Please not the polarity as you replace the capacitors.. Good luck
I switch on my PC, ensuring that all cables, leads
and power supplies are connected properly. The tower powers up no
problems at all. I switch the screen on, the green led lights up, the
screen is completely black. A blue box appears centrally on the screen
with the text 'power saving mode'. The green led light turns amber and
then the screen just goes black.
Please don't suggest going to control panel, as I can't get that far.
What do you mean your screen goes black. It is black to start isn't it? Does it come on at all?
If you meam you are getting a display, but it goes off, you need to check the power settings for your monitor, that are set by your PC. Click start, then control panel, then double click display. Then in the Dispay Properties window, click the Screensaver tab at the top middle.In the lower half of the page which opens, you can find power settings, and the rest is self explanatory. If this is not the answer to your problem, you need to give more detailed information.
One check you can do is to disconnect the signal cable from your monitor, and switch power on, and see what is displayed. You may well need a new monitor, but before running off to buy one, try to borrow one to connect to your pc, and also if possible, try to connect your monitor to another pc, or to a notebook/laptop.
sorenke, Monitor "switchmode-mode-power-supply" going into shutdown mode when detecting a FAULT CONDITION with some other circuit or with itself. Your monitor has same technology as any other backlit lcd display!! Read more of my responses to owners that have BLACK screen problems. Some have BLACK and BLANK screen problems Do you know flashlight test of SMPS status? How old is unit? How many Total "ON" hours unit have? Do you know what a bad electrolytic filter capacitor looks like? Have you been to YOUTUBE yet? 12fixlouie
check your vga cable that is connected on your cpu,for some lose connection,it must be fitted if you still don't get any display check your cpu.have some other monitor for isolation,if you dont have bring it on s repair center,your cpu has a problem.
Hi, I don't think the problem is with your monitor. Your monitor sounds like it's doing exactly what it's supposed to do. The monitor is supposed to turn off if there's no cable attached, which means there's no signal input. When the screen goes black, does the power light stay on and turn orange? or does it go off as well? I would recommend that you lower your screen resolution to 1280x1024 or lower in the Display Properties window, then remove your primary monitor, and connect the monitor to your desktop computer. You should see it light up when connected. The monitor auto-senses when there's a computer attached to the cable and when there's a signal. If it doesn't see a signal, it goes black to save power.
I have the same problem its defenitly a problem with the lcd monitor not with the graphics card nor the pc. I hooked up the digital and afterwards the vga connection both had the same result. 1 s perfect screen all visible but than black. pushing the on/off or standby button again shortly 1s the display works than it blanks. Did the same test while connected to a dvd player via the composite video... same problem . Since the previous posts are that old and without a solution I guess there is no hope in getting it fixed.
