It may have failed power supply due to bad DC filter caps or bad backlight inverter circuits. Iwould look for bad caps first, then check to see if it has 12vdc feeding the inverter circuits.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

DELL 2208WFP LCD-Comes on normally, but almost immediately goes dark You can see something on the screen if you look closely. Turn it off and back on you see it then dark. any help?


Hello,

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

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.

Syncmaster 226bw goes black


If you can still faintly see data on your screen, it will be a faulty backlight in the panel most likely.

LCD panels have fluorescent tubes in them that provide the light needed to see the data. If one of these goes faulty, the circuit that drives it will turn off ALL the backlights, giving you a black screen.
Note: a faulty circuit that drives the backlights will often give the same apparent fault.
You will need to take the monitor in for repair.

When I press the power button LG displaying chars for 1 second


Had the same problem, turned out it was due to a faulty capacitor on the inverter board, 680uF 25V (105 celsius rated). Simple to fix once you have the unit dismantled and the correct replacement part. Two screws hold the shroud on, but you need to be careful with an (old) credit card levering it off.

Unit is now working fine.
