Hello mat78, Unfortunatelly the problem is hardware based. You will need to have the monitor repaired in a service center. Here's why: LCD/TFT monitors don't produce light themselves. They are composed by a matrix of transistors (TFT - thin film transistor) that have the property to reflect or allow some light (certain wavelenghts)to pass through them. They don't produce light by themselves. Instead there is a fluorescent tube (neon like) light inside the monitor and that's the light source used in order for you to see what's on the screen. A flourescent light is suposed to last pretty much, i don't think yours has a problem, you say it works for some seconds or so. Instead your problem is most probable with the inverter circuitry that powers on that light. It's a common problem among these types of monitors but in your situation i don't think it will be an expensive repair. In the case that the screen is dark (in a dark place you can't read or view anything on it) but if you apply light to it ( a flashlight or something) and you see something, then the problem is most likely to have occured with the invertor. Try to ask at a local service center for a repair, this shouldn't be an expensive procedure. Hope this helps.

SOURCE: monitor goes black

Sorry to have to tell you this, but this is common in LCD monitors. The reason that it is going black when it boots is for one of two reasons. You either have a bad power supply that powers your LCD or your LCD's backlight is blown. These can be repaired or you can purchase a new one. But if it goes black 9 times out of 10 is because the backlight is bad. These can be repaired!

can you test your monitor on another computer to verify the monitor is at fault? If the monitor is at fault its time for a new one, factory warranties on monitors are usually 1 year unless you purchased an extended warranty.Otherwise repair is usually more costly than buying a new one.

I have fixed many of the al1912 easy fix

the problem is always corrosion on the circuit board that has the buttons
disassemble the flat panel remove 3 screws that hold button board on
disconnect the tiny cable from the button board
use a tooth pick and clean inbetween the solder connections where the ribbin cable plugs into button board

Turn the monitor ON and continue to hold the power button for a few seconds.

Worked for me :)
