SOURCE: Power Light Blinking & Black Screen
A blinking blue light indiactes that your power-inverter board is not
putting out what it should. It needs an overhaul which may be a simple
as changing out the capacitors on the boards.
It could go beyong that to transistors or even a bad bulb.
It will have to be opened up to do that.
A picture may show visual signs of damage. If you can take one and email it to me , I'll take a look.

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
Change two electrolyt capasitor 1000u/16V to your power supply.
SOURCE: I have an LG monitor, that doesn't power up. The
Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, falied 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 goes wrong: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further.

Try connecting to a different computer to insure it isnt the video board of the PC. If same results it is in the monitor. What I've seen a lot lately is capacitor problems especially on the power board. if you are willing to open the monitor then you should see two boards, one for power and backlight AC power (should have 4 plugs into it all the same). Look at the can shaped parts that have stamped in marks on top, usually looks like a K. If they are all perfectly flat then it's something else, maybe the other board that handles the video. If they are humped up (swollen on top) or have a residue (leaking) then you will need the capacitors replaced with the same microfarard (uF) value and voltage value positioned the same polarity as the old (dashes on one side means negative side). If it has 25V capacitors you can use 35V but not 16V. You can go up one series of voltage but not down. Capacitance in uF needs to be the same.
