My monitor goes for 3 seconds black, every 1 minute

First thing, try to connect the monitor to another CPU and see if its gonna work. If it doesn't, then this might be a capacitor failure. One of the capacitors in your monitor that are responsible for holding up power for proper display is faulty. A faulty capacitor is either bulged(with a hump head) or burst. This causes the monitor to go off a few seconds after you switch it on because the capacitors can no longer hold power long enough for your display. One way to work this around is to take your monitor to a Computer Technician to open it up and probably replace the faulty capacitors

Having a LG Flatron L1718S. In the last week, when I start the monitor it shows about 1 second the image of the computer, the it turns black. Same appears when I disconnect it from the computer - a...

That means the monitor has a problem with the Capacitors. Capacitors inside your monitor can no longer hold up power long enough for your display. This is so because the capacitors might have been blown. This makes the monitor to go on for about 2 to 3 seconds then it goes off.

The solution is to change the capacitors from the board (the part that you connect he power cable). This must be done by a Computer Technician who will safely carry out the procedure. Open up the monitor, using a flat blade and try to separate the cover with the LCD, starting from the bottom, working your way through around. Before you do anything, check for any burged or any with a black smoked colour capacitors...If you find any, then it has to be replaced

My LG 23SL7D will not stay on, it temporarily will connect to PC then screen will go black.

If the screen keeps going black and you know thet your graphics card is ok (test monitor on another computer), then the issue is probably with the internal monitor power capacitors, which you will need to take to a TV repairman to have inspected

Monitor going black

HP's are known for bad capacitors in the power supply.
Replacing them is simple if you know how..not so simple if you don't.
Try your local TV repair centre. It should not cost alot to have the capacitors replaced.

Hope it helps =)

E153FP Monitor screen goes black light is green

The capacitors are probably bad. It is a common problem and easily fixed by taking it apart and replacing the capacitors. Try to find Rubycon Capacitors because they very rarely go bad. Do a search on google for bad caps. I have fixed about 30 monitors this way. Dell is a company well known for bad capacitors. It may not be your problem but replacing the capacitors should cost less than $10 if you do it yourself.
