Hello,

This is a very common problem on many LCD monitors after a few years of use. If you can solder you should be able to repair the monitor yourself. The problem is caused by blown capacitors on the power board. Go to our web site at : www.ccl-la.com/badcaps.htm We have pictures of what to look for. Open your monitor and look at the power supply board for any blown capacitors, replace all that you find. The replacement parts can be ordered from several places on the internet or we can supply them for you. The replacement parts will need to be high temp and will be marked 105c. The values you need to get will be marked on the sides of the ones you take out but will be something like 220uf, 470uf, or 1000uf etc. and then a voltage rating. When you install the new ones be sure to insert them with the polarity stripe going the same direction as the old ones come out. If you don't want to do the repair yourself we do offer a repair service for $35 plus return shipping. If you have any questions just let us know

I hope this helps if so please rate our solution.

Why does screen go black after a few seconds

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.

To fix this black screen problem, change the inverter board (based on your monitor brand).

Is this a laptop?
This a common problem for monitors, especially on laptops. This cause by the inverter board. The inverter boosts voltage to light the screen. When goes bad they go bad they often work for a few seconds. If you look closely you can see the screen but the voltage is not there to get brightness.

My AOC screen goes black after about a few seconds after booting.

Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer or 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 order not to complicate issues.

Take care.

Hello,

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

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.

Samsung monitor picture clicks off after 2-5 seconds...

Yes, It sounds like the backlight inverter circuit is shutting down. No inverter power, no backlight. On some monitors the inverter circuit will shot circuit the power power supply which makes the power light flash on some it just kills the backlight. You can usually check with a flashlight. Hold the flashlight pointed at the screen and see if you can see any of the icons or background picture. If you can then it is the backlight circuit or backlight tubes, usually the circuit.

Monitor only stays on for 3 seconds

There is probably a bad capacitor within the monitor that will not allow the picture to "hold" in the on configuration. This will need to be replaced. You can send it back to Phillips, or 17" monitors are pretty cheap these days. I would suggest a Samsung or BenQ. They both carry 3yr warranties.

TV Picture Goes Black

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
