Monitor turns off after two seconds

I moved and went to hook my computer back up and the monitor comes on for about 2 seconds and then turns off. If you turn it off and back on again it comes on and repeats the same issue. I bought a new cable and the problem still exists. I packed it very carefully?

    Monitor comes on momentarily after startup then turns off and green light blinks. By powering the monitor on and off, eventually the monitor will stay on. Almost like a problem related to warm up. Power supply???

The solution was not a backlight problem. Backlights have different failure characteristics than was stated. The problem turned out to be several defective (open) electrolytic radial capacitors. Found by trouble shooting the pc boards with a good cap tester and replacing the defective caps. Works great....now!

Caution on Inverter advise...
If the inverter is bad, you will still see non-backlit video on the lcd screen if you look real carefully. It will be very faint, but you will see it, especially if the video being displayed has alot of contrast.

The job of the inverter is to provide starting power to illuminate the LCD's fl lamps and then maintain the selected intensity. The video is a separate issue and will always show on the LCD. So, if your monitor powers up and if you are positive that there is a video signal going in to the unit and you cannot see a faint image of it, do not bother with the inverter, it is not your problem, it is the LCD itself or the video circuitry (very expensive to repair. Trash unit and just get a new one)

Your inverter board is bad. They run anywhere from $30 - $80. They are very easy to replace. I have had this problem with three monitors and replacing the inverter board fixed the problem. Hard to say where you will find the part. Just do a search for 'inverter board' with your model # on any search engine.
Good Luck!

Monitor goes blank less than a second after turning on.


Sounds like either there is a bad connection from the computer to the monitor, or the monitor has a faulty power regulator, causing the monitor to overheat prematurely, and shut off.

Monitor problem


I have had similar problems. It would appear that the power supply is at fault, not the monitor.
