    I am experiencing the same problem with this only difference; I get no display from my PC, however I can access and view the OSD without issue. If the inverter were the problem, would I be able to see the OSD?



    Thanks!

Replace your monitor, it's broken

Your backlight inverter is likely to be broken, can't hold the charges.

Part#: DAC-12C024MSS

Hi,

There could be a couple of possible reasons for your problem:
1. All LCD displays uses CCFLamp to illuminate and provide backlight to the panel. More often they burn out or thier connectors gets corroded or the circuitry that powers these lamps gets defective. Defect can either be component failure or loose/cold solder joints. At times it could be the capacitors that dries out or have developed blisters on the top portion.
2. There had been cases where it is the power supply of the monitor that is in problematic.
3. In some cases, it is not the monitor that has a problem, it may be the video card of and/or the PC itself. This could be confirmed by using another monitor to eliminate this possibility. At certain times, it may be due to the Screen Resolution settings of the PC or the Screen Refresh Rate.

Things you can try:
a. Boot your PC normally even if you cannot see anything. Shine a flashlight obliquely to the screen. If you can see semblance of your desktop no matter how dim, then you have just confirmed that it is the backlight/CCFLamp or its inverter that is the problem. this is repairable but would require that you be familiar with electronic components and circuitry, use of a DVM and a soldering iron;
b. Internal or external power supply for LCD display panels/monitors are likewise repairable. Again the same requirement if you are to proceed doing the repairs.
c. Adjusting the Screen resolution and Refresh Rate can be done in the PC by booting into Safe Mode and lowering the settings.

Should you not be comfortable on options 1 & 2, perhaps your best bet would be to seek the services of a qualified professional.

Hope this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

My screen only shows a picture for a few seconds


Try connecting a different monitor to your computer, to see if that monitor shows the same symptoms. If so, your computer, not your monitor, is the problem.

Try connecting your monitor to a different computer (desktop or laptop) to see if the problem "follows" the monitor.

VX900 19 in. Flat Panel LCD Monitor: when i turn it on the screen is black....


You may have backlight inverter failure, check the fuse as shown in my pictures, you can also have bad backlight assemblies also, but check the fuse on the inverter bd first, verify that you do have 12v at the fuse.
