Dell Blinking Power Light

I have a Dell 17" LCD E173FP, that has a blinking power light on the power button. When I plug in the LCD, no other lights come on, and the power button starts blinking. The screen also stays black. Any Ideas anyone? Thx guys and gals.

    All three lights on my dell 17 inch lcd are blinking (1,2 and the Power LED). The power LED actually blinks in the amber color.

    Mine is a dell e172fpb. When you turn on the monitor the green light blinks and windows flashes quickly and the screen goes black. I have an extra monitor and when I switch monitors it works fine. Its obviously a monitor problem and not a video card problem.

    My monitor's green power light blink on and off. I see a brief flash of the screen, and then the monitor appears to blink on and off, black and blacker, no real image. I unplugged and replugged, and checked connections.

    I have 2 of these worthless monitors, of course Dell will not say or agree there are issues. the model # E196FPf. If it's out of warranty you can basiclly say your getting the big shaft. They will do absolutely nothing. It appears the made in China quality still sucks!



    what happen to made in America?

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.

There are 4 transistors that go bad due to various issues (one being a cold solder issue with the power inverters for the transistors. I had this fixed and replaced the transistors. They lasted about 10 months). The 4 No. 2SC5707 transistors must be desoldered and removed, new ones put in their place and resoldered. I took the parts (transistors) and the removed power/circuit board from the LCD to a tv repairman and he did the repairs (de and resoldering) for about $60.

I just fixed one of these, and it was one bad cap. Also I put a heat sink on the 4 transistors as they had no heat sink at all. I soldered
a small piece of tin to the back side of each one, and bent it over
out of the way.

When it have this kind of error is a problem of the powerboard.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.

But can be a problem with inverters... control the transistors - MOSFET on the powerboard.

Good luck!

Dell stuck in power safe mode

A blinking power light is not indicating power safe mode, it indicates a failure of the power supply board in the monitor. Here is a link to repair guides that show how to open and repair the power supply boards in the Dell E173 series of monitors;

My Dell monitor wont get out of the power saving mode. I unpluged and disconnected everything. Then pluged back. Still same problem.

It is more likely to be bad inverter cicuits due to shorted out transistors (four c5706/5707). The power light blinking?

My dell e173fp monitor has quit working. The power light continually blinks when power is applied, even without having to turn it on. An identical substitute monitor works fine on the computer system. ...

Is the power blinking amber? This is a DPMS power-save mode. With the computer disconnected and the monitor on, do you see the colored self-test block floating around? With the monitor on, computer connected, and you still have no image displayed, take a bright flashlight and examine the screen closely. If you can see a very dim display in the screen, the fluorescent tubes which light up the *background* and provide the vivid picture(sort of like a how an x-ray picture viewer works) are defective. The power light blinking may be the power supply sensing the non-functioning tubes or it could just be bad. If your display is under warranty, replace it. If not, trying to have the monitor repaired for this type of problem is almost as costly as a new one--and there won't be an active warranty on anything else that might fail. Hope I helped you.---Rick

Dell LCD Monor light keeps blinking green, screen is black cannot stop blinking unless unplugged from power source but upon plugging back in monitor starts blinking green again

Hello,
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.

Dell Blinking Power Light

Hi There,
I have worked on several of the Dell 17" and that is almost always the Capacitor problem.

The caps have died inside, and they can be replaced. If you have basic electronics skills, you can go in, order replacement caps, and unsolder and resolder. If you can't do it yourself, you can take it into a shop.

If you can get inside the frame of the monitor, and disassemble, you can find the caps by seeing a bulge on top, or even a rusty looking material on the top. Be VERY careful around the high voltage section if you do go inside.

Here is a link to the Cap plague that explains what happens in detail. But I repair these all the time with that symptom.

That sounds like the backlight inverter board. Check ebay for the board or a repair kit for it.
