Your internal power supply has failed. The failure is caused by heat buildup in the monitor case, a common problem. The heat causes parts called capacitors to blow out and short the power supply so you get the flashing power light and no display. If you can solder then you should be able to do the repair yourself. Go to our web page at :
www.ccl-la.com/badcaps.htm and look at the pictures of what blown capacitors look like. Now open the back of your monitor and remove and replace all of the capacitors that look like the pictures and you should be back going again. he values you will need to purchase will be marked on the sides of the ones you take out but will be values like 220uf, 470uf, 1000uf and then they will have a voltage rating. You will need to get high temp caps marked 105c or they will just blow again in a month or two, parts from Radio Shack will not work. You can order the correct replacements from several places on the internet, just do a google search or we can supply them for you. When you install the new caps be sure to insert them with the polarity stripe on the side going the same direction as the stripe on the old capacitor. If you have any questions just email me. We also offer a repair service for $30 plus return shipping if you don't want to do the repair yourself.
I hope this helps, If so please rate our solution.
