I had a similar problem with an LG monitor that I resolved by connecting the analogue cable as well as the digital cable from the pc. This problem must be caused by the monitor not receiving a digital signal.

Hi My screen developed exactly the same problem. It appears to be a hardwear problem associated with the screen it's self. continuity test is ok on the lead so I took it back to the shop under warranty and hey presto, the replacement works. I don't know what the problem is but there are a number of other folks on another thread with the same problem and their entries are dated May 09 too. Dave

There should be a menu button on the monitor to change it to digital. It should be labeled source. It should be on the front second from the right.

It can be as simple $5 worth of caps in the power supply.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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 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.
