Usually when the power light flashes and the screen remains blank and unlit, your power board is in fact malfunctioning. This is not always the case, as the problem can sometimes reside in the input or inverter boards. I would first recommend that you feel comfortable with opening up your screen and looking at components. It can be a little overwhelming at first. BEFORE PROCEEDING, UNPLUG POWER TO MONITOR. If inclined to check, carefully open the casing around your screen. I have not worked on your particular model, but some are easier to open than others.
Once opened, you need to gain access to the circuit boards. Sometimes they are not protected by metal, other times they are completely encompassed. The flashing power light usually indicates that a capacitor(s) is(are) malfunctioning. To see if this is the issue, locate the power board (usually the one with larger-size components) and look for any capacitors having bubbled or raised tops and/or oozing a brownish liquid. If not on the power board, look elsewhere for the same symptom.
PLEASE BE CAREFUL!!! If you have recently had your monitor plugged in, the larger capacitors can still carry a charge. If you cross the leads of a capacitor while it carries a charge, it will discharge. It won't hurt any other components, but if you cross the leads with something that is in direct contact with yourself, you can get quite a jolt! There is usually a large voltage capacitor (normally just one) on the power board of these screens. I tested one with a multimeter after immediately unplugging it, and it still held a 166V charge! So please, do this with caution.
If a bad capacitor has been found, simply remove the old one and solder a new one in its place!

You have a monitor with a common problem. After a few years some LCD monitorswill blow a power supply. The problem is caused by parts calledcapacitors overheating in the confined space of he monitor. If you aregood at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htmYou can take the back cover off your monitor and look for the bad parts,replace any that look like the pictues and your monitor should workfine. The capacitors do need to be installed with the correct + and -connections, note the stripe on the old one and insert the new one thesame way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

Check the four transistors (c5707/5706) in the inverter section for shorts, board looks like this? http://www.lcdrepair.us/e152-e153fpb-inverter-power.html
