You have a classic capacitor problem. If you are ok with soldering you should be able to repair it. You can remove the back cover and look for the bad capacitors, replace any that are raised on top. I can send you pictures of what to look for if you need them.

SOURCE: monitor goes dark
If the power light turns yellow, there is no signal being received by the monitor from your computer's graphics card. The screen will shut off (go into idle mode), which is a low-power state, that saves energy. Check that the cable on the back of your computer is plugged into the right graphics card (many PCs come with more than one, these days). There may be one built into the computer's mainboard, and another one may be on a separate graphics card located somewhere else on the machine. Only one of these will work on startup. If one doesn't work, try the other.

The LCd panel may be damaged and will cause this problem.
Another thing is overheating of the GPU.
The LCD signal receiver can be goign on you.
The is also the possibility of a faulty inverter.
Only thing to do is service or replace. Test the unit on another computer, if you don't get the issue there then you know its a problem with the PC.

The solution I am about to describe refers to a backlight problem, which is most common in Dell 15,17 & 19" monitors. The symptoms are as you describe:
Inside the monitor there is an inverter board that acts as a power supply for the monitor and the logic necessary to control the backlights (illumination and brightness control). There are four lighting tubes, which are controlled by two lighting circuits (two lighting tubes per circuit). At the heart of the inverter board is a chip that monitors feedback from the two lighting circuits and closes the back-light circuit down if either of the lighting circuits fail, thus any component failure will exhibit the same symptoms.
The transistors which fail most often cost pence to replace (types C5706 or C5707). However, their failure in unlikely to be the cause of the problem. My first crack at fixing this fault, by replacing the transistors, resulted in them failing again within 24/48Hrs. The cause of the problem will be dry solder joints or loose connections on the high-voltage side of the circuit, usually on the backlight transformer in the effected circuit. If you re solder each of the connectors on the transformer you will save the transistors from blowing again - the transformer generates 1,400Volts for the lighting tubes and at this voltage, arcing across the a dry solder joint, will quickly destroy the transistors again.
No soldering iron? - A complete inverter board replacement is also reasonably cheap and easy repair. These are widely available.
Sorry of this is more detail than you expected but it may help others reading this article.

To me this sounds like your LCD screen is bad . I had this happen to me
On a samsung security system 19'' had it repaired works great now.
