You've worked it out, just don't want to see the result. Your monitor has bitten the dust. This is fairly typical of capacitors in the monitor power supply failing.

They can be replaced so long as you're good with a soldering iron. You need to look for capacitors on the circuit board which look as though they bulging, especially at the top. Or yellow staining on the circuit board under the failed capacitors. If you can't spot them, then you need to measure them with a voltmeter.

Picture won't display after a few seconds


this is either the flourescent bulbs are going out or the power supply has bad capactors on it. You might open it up and look at the power supply board for capacitors with their ends that look like they are "erupting" on the ends.. this means they need to be replaced.

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.

I have an Acer AL1912 that when you plug in the ac, the green power light will blink for about a minute and a half then go solid. The backlight will come on and you can see a faint ghost of vertical lines...


If it is still in warranty call the manufacturer.
if not give more info elah4@zoominternet.net. May be somthing simple like a cable
shutdown computer unplug then disconnect the video cable on the computer from the monitor, plug monitor back in and turn it on, there should be a display that says no video source within a few seconds, if unit is working properly. shutdown and connect video again and then reboot computer. sometimes it just takes a compleat power disconect to reset things,

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.

No picture on my x5g-komodo7 monitor


A reddish picture is the classic symptom of worn out backlight bulbs.
Sensor circuits usually shut down the power to the bulbs in a second or so.
