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.

SOURCE: Dell Blinking Power Light
Just wanted to say Thank You for the info on this site. I had the same problem as previously posted. When powered up, the monitor showed a fast flash of the desktop and then went black, with the power indicator flashing green. I read the posts, purchased the capacitors and the 4 - 2sc5707 transistors through ebay. I ordered them on the 6th and rec'd them today. I only had one bad capacitor and one transistor that checked bad, but I ordered 5 caps and 4 transistors. When ordering the caps be careful of the height of the caps. I found this to be a problem because I ordered the 50v, 105 degree Panasonic caps that didn't fit with the enclosure attached, so I used the 4 good caps removed previously and replaced the bad one with a 470uf, 50v. 85 degree cap from Rubycon I found among my spare parts. Installed the parts and the monitor is working properly (for the last two hours) so I'm happy for as long as the repair lasts. Thanks again for the info.

wjfarm48, Sure sounds like a power supply problem. How old is it? How many hours of use? Do you understand what a switch-mode-power-supply and an inverter supply is? If not, then here are your options. Check with Gateway to see if there is a swapout program. You box up and ship them your monitor+cash, and they return a REFURBISHED same model with new CCF tubes and inverter/SMPS. When you box up the monitor, follow this lead. "A 3 inch thick layer of breathable air shall be the only thing touching the lcd front panel" Next option is find some local TV/Monitor repair guy who can get parts and or replacement boards/CCFtubes from Gateway. Last but not least, is to repair yourself. Not Recomended.. But do a search on lcd monitor repair or Bad Capacitors In LCD Monitors or Repair of SMPS in LCD/FPD Monitors. Also check for videos on YouTUBE related to lcd monitor repair just for your own info. Here 's what you are dealing with. The light that makes your FPD bright white is generated by Cold Cathode Fluorescent Tubes (2) that require 600-1200vac at high frequency that is generated by an INVERTER which gets 12-24vdc from the SMPS. Almost the same technology is used in the new style screw-in curlie-que Compact Fluorescent light bulbs. Only they call the inverter a electronic ballast. Anyway, thats about all the info I have. Let me know how you make out in you quest to get your LCD up and running again. I'm louie12fix on fixya or lmistyrel@ aol.com BYE for now.

Your monitor has a bad power supply board. This happens often on LCD monitors because of the heat buildup in them. If you can solder them go to our web site at:
www.ccl-la.com/badcaps.htm We have a step by step dis-assembly and repair guide for your monitor. There are several versions of the E173FP some end in b , f, or c so be sure to check your monitor.
I hope this helps, if so please rate my solution.
