SOURCE: Monitor powers on for appx 1 second then goes dark. LED is on.

Hello,
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.

SOURCE: I have a Dell SE198WFP Flat Panel Monitor, screen goes black?

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.

SOURCE: I have a Dell monitor model #1901FP when my

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:

  • You power on the monitor, the green on/off switch illuminates and the display works for approx 1-2 seconds and then goes blank.
  • The green on/off switch stays illuminated but the screen remains blank
  • If you shine a torch into the LCD matrix you can see the display being rendered faintly
  • Switching the monitor off and then on again illuminates the display again for 1-2 seconds before going blank again
This is a backlight fault and is most likely to be caused by the failure of two of the four driver transistors used to light the lighting tubes in the LCD Matrix. This fault is easy to repair if you (or a friend) have a soldering iron and a voltmeter.

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.

DELL 2208WFP LCD-Comes on normally, but almost immediately goes dark You can see something on the screen if you look closely. Turn it off and back on you see it then dark. any help?


Hello,

I believe the power led button is still on while the screen goes dark, if yes, it means the picture board of your monitor is bad that is why it appears for a second and goes dark after that

Since the power led button is on, It means the picture board on your monitor is faulty that is why it appears for a second and goes dark.

The best thing for you to do now is to take the monitor to a local repairer or any service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself in other to complicate issues.

Take care.

Screens goes dark after 3 seconds


Your power supply probably has a blow electrolytic cap on it.

You need to pull the power supply board out and have someone replace the electrolytic caps on it. Believe me....if the one for the brightness is bad...they are all suspect!

Caps are cheap...but knowing how to open the monitor and do the soldering is the part that takes some skill and may be costly.

Good luck and be careful.
