The problem is most likely it burned out back light. If your screen turns on but you can't ever see anything on it, it is the back light that is not working. You can possibly fix it depending on the exact model, however, it is usually cheaper just to buy a new one.

SOURCE: hi everyone , ive got a LG Flatron monitor model

Check out for bad caps in the power supply first.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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 LG and other monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Several things, it could just be turned down real low but most likely it is not getting a signal from the source. What color is the light on the bottom. If it is not green you have an input signal problem.

Monitor comes on and goes right to a black screen like the power was turned off but the power light is still green.


hi,
You have to check the back light of your lcd monitor. All lcd screen have a back light to illuminate the pixels. you can conform is the back light is faulty or not by watching the lcd screen nearby. Watch can you see any image (negative image) on the screen. you have to look very closely. if you see any image on the screen then the back light or the back light inverter is faulty.

You have to check the back light inverter board. Normally in lcd monitors you can see three circuit boards. power supply, mother board, and the inverter board. If available then try to replace the inverter board. There are high voltage transformers in this board. There is a chance for its winding get short. You will not get the transformer in open market. Try for the inverter board .
ok

Monitor keeps turning off but power says it's still on


You are OK with the power cord, more likely to be failure in the power supply/Inverter board, look for bad fuse and shorterd transistors, see Dell pictures here: http://s807.photobucket.com/home/budm/allalbums
Transistors should be checked out off circuits.
